API and MCP

Portfolixir exposes the supported local workflow through the JSON API under /api/v1. The MCP companion in mcp-server/ is intentionally thin: MCP tools call the JSON API only and do not access the database directly.

Authentication

API requests require a local bearer token:

Authorization: Bearer <PORTFOLIXIR_API_TOKEN>

Named tokens (E25). PORTFOLIXIR_API_TOKENS adds further tokens as name=token entries, comma-separated (scripts=<token>; a name is 1 to 32 characters of a-z, 0-9, _ and -). A write made with one is journaled with that name as actor_label (GET /api/v1/journal), and a merge applied with one records it on its merge record (GET /api/v1/merges), taken from the entry the presented token matched, never from the request. PORTFOLIXIR_API_TOKEN stays the default, journaled without a label, as before, unless PORTFOLIXIR_API_PRINCIPAL names it; the Compose deployment names it mcp that way, so the companion’s writes read mcp. Every entry is checked at boot like the one token, and a name or a token may appear only once. A name attributes a write; it does not narrow what the token may do: every token has the same full authority. Why, and the boundary for stored text below, is decided in ADR-0054.

The MCP companion uses PORTFOLIXIR_API_TOKEN to call Portfolixir at PORTFOLIXIR_API_BASE_URL, and it follows no redirect from there: a 3xx answer is refused as ApiRedirectError, naming the request and the variable, so a request’s body and the token are never resent to wherever the redirect points. Point PORTFOLIXIR_API_BASE_URL at the address the API answers on without a redirect. PORTFOLIXIR_MCP_TOKEN is required for HTTP transport so local HTTP clients can authenticate to the companion. It meets the API token’s policy: the companion refuses to start with a token shorter than 32 bytes or equal to a placeholder, naming the variable. A PORTFOLIXIR_MCP_PORT that is not a whole number from 1 to 65535, or a port the listener cannot take (another process holds it), stops the companion with exit status 1 and one line naming the variable and its value, or the address and the cause, such as EADDRINUSE. An empty or blank PORTFOLIXIR_MCP_HOST binds 127.0.0.1, as an unset one does, never every interface (#1137), and so does an empty pair of brackets ([]), which reads as the loopback default as an empty value does; an IPv6 address it binds is answered in brackets ([::1]:4001), the Host a client sends for the URL the companion prints. Repeated wrong tokens from one connecting address lock it for a growing interval, during which every further wrong token from it is answered 429 with Retry-After and extends the lock. The token is compared first: a correct token passes while its address is locked (#974), so behind the published port, where every client connects from the Docker bridge, a guesser or a stale client there does not lock the agent out. The API’s own bearer check behaves the same way while every token it is configured with meets the 32-byte floor; a server run from source that reads PORTFOLIXIR_API_TOKEN alone holds it to none, and with a shorter token it consults the lock first. Before anything else, the companion checks the Host header exactly, name and port: a request under a Host the listener does not answer to (the loopback names and its bound address with its port, and the names in PORTFOLIXIR_MCP_ALLOWED_HOSTS) is answered 403 before its origin or its token is looked at, and counts no failed attempt. The loopback names are 127.0.0.1, localhost and [::1], each with the listener’s port only. A name in PORTFOLIXIR_MCP_ALLOWED_HOSTS is answered with that port and without one, as a proxy on port 443 passes it; an entry that carries its own port is answered under that port alone, such as 127.0.0.1:14001 for a Compose mapping that publishes the companion on another host port than its own. The names, the bound host’s and those in PORTFOLIXIR_MCP_ALLOWED_HOSTS, are compared in lower case, as a browser sends them, so an entry written with capitals passes both the companion’s check and the MCP SDK’s. A browser request’s Origin is then compared whole, scheme, name and port (#956): it passes as http:// on a loopback name or the bound address with the listener’s port, or as http:// or https:// on a Host value from PORTFOLIXIR_MCP_ALLOWED_HOSTS. Any other origin, a page on another port of the same machine included, is answered 403 (origin not allowed) before its token is looked at. To admit a browser-based MCP client served from another origin, name that origin’s host and port in PORTFOLIXIR_MCP_ALLOWED_HOSTS: localhost:6274 admits a client served at http://localhost:6274. A client that is not a browser sends no Origin and passes this check. The token is checked before the request body is read. The errors the companion answers itself, an unknown path among them, take the API’s shape, {"errors": {"detail": "Bad Request"}}, with no stack trace or local path in it; the refusals of the MCP protocol itself on /mcp keep the protocol’s JSON-RPC error shape.

Data Rules

All responses use JSON envelopes with either data or errors. Financial decimals are serialized as strings, including quantities, prices, fees, taxes, quote closes, and monetary totals. Request payloads for those values should also send strings.

The errors the server answers itself, rather than an endpoint, use the same envelope with their own status: an unreadable body is 400, a body over the server’s size bound 413, an unknown route 404, an internal error 500, each as {"errors": {"detail": "Bad Request"}} with the status’s reason phrase.

DELETE /api/v1/securities/:id is the success exception: it returns 204 No Content with an empty body. Clients should not parse a JSON body for that successful delete response.

Ids. Every id is a positive integer that fits a PostgreSQL bigint (at most 9223372036854775807). A path id that is malformed, unknown or past that bound answers 404; an id past the bound in a query string or a JSON body (at any depth, as a number or a string) answers 422 naming the key, the same field error a malformed id gets. No id is ever answered with a 500. A security’s free-form attributes map and the text fields online_id and resource_id are not ids and are not checked.

The pages keep the same promise: an id-shaped query parameter past the bound (id, *_id, *_ids, view) is dropped by a redirect to the same page without it, and a path id past the bound (/securities/:id, /classifications/:id) redirects to the index whatever the query string carries — never a server error. Every other id-valued or integer page parameter is read by the same id rule and reads as absent when it cannot hold the value: /snapshots?snapshot= opens the newest snapshot, and /tax?year= (a year outside 1–9999) the default year. An event a page or one of its dialogs receives with a payload that is not an object, an id past the bound at any depth (the same rule the API answers with 422), a field of the wrong shape, or a name it does not know changes nothing: the page stays as it was.

Bounded integers. offset on the securities list accepts at most 1000000, and days on the research log’s unreviewed and expiring reads at most 3650 (ten years); a value above the bound, or one that is not a non-negative integer, answers 422 naming the parameter. limit keeps its capped-and-echoed contract, and so does the security events’ days. A year outside 1–9999 reads as a malformed year.

Dates. Every date a write stores — a booking’s date, a rule version’s valid_from and a retirement’s valid_until, a snapshot’s as_of, a research-log entry’s, an event’s, a tax profile’s, an ISIN change’s, a quote’s and a split’s dates — is an ISO 8601 calendar date (YYYY-MM-DD) from 1900-01-01 to 2999-12-31. A date outside that range, or sent in any other form (an object of parts, a date-time), answers 422 naming the field and stores nothing, so the date stored, answered and journaled is the date sent. A Portfolio Performance import names a row dated outside the range in its preview instead of booking it. A read’s date filter — from and to on the transactions, quotes and trades reads, as_of on the security metrics and policy-rule reads — meets the same rule: anything else answers 422 naming the parameter.

Ledger amounts. A booking’s money fields and prices (gross_amount, price, fees, taxes, security_amount, settlement_amount, settlement_fx_rate) keep 6 decimal places and its quantity 12 (ADR-0016). A finer value is rounded half up to that scale before it is checked, so the value stored, answered and journaled is the rounded one, and a positive amount that rounds to 0 answers 422. A value with more than 14 digits before the decimal point (a quantity more than 18) answers 422 naming the field instead of failing in the database.

Other stored amounts. The same rule holds for every other amount a write stores: a quote’s close (6 decimal places), an exchange rate (15), and the tax writes’ money fields (6) and rates (4) — a statement snapshot’s pots and withheld taxes, an allowance order’s amount_granted, a tax year’s allowances and rates, a profile’s church_tax_rate — and a bond’s coupon_rate and face_value (6). A finer value is rounded half up to its scale before it is checked, so a positive close that rounds to 0 answers 422 and is never stored as zero; a money value with more than 14 digits before the decimal point answers 422 naming the field.

Text. A name, an identifier or any other one-line text a write stores is at most as long as its column — 255 characters unless a narrower limit is stated (a bucket’s or view’s name 100, a plan’s or snapshot’s name 120), counted in Unicode code points, the unit the database counts — and carries no control character and no line break. Free text (a booking’s notes, a research-log entry, an event’s or a rule version’s note, a description) keeps tabs and line breaks but no other control character, a NUL included, and is at most 10000 characters long (a research-log entry’s body 20000, a category’s description 2000), counted in code points; the database refuses a longer value as well. No text, one-line or free, carries an invisible character (E25): a Unicode tag character (U+E0000–U+E007F), a bidirectional control (U+061C, U+200E, U+200F, U+202A–U+202E, U+2066–U+2069), another invisible format character (the soft hyphen U+00AD, U+180E, the zero-width space and joiners U+200B–U+200D, U+2060–U+2065, U+206A–U+206F, the byte-order mark U+FEFF, U+FFF9–U+FFFB, U+1BCA0–U+1BCA3, U+1D173–U+1D17A) or a run of two or more variation selectors (a single one, an emoji’s presentation, passes). A zero-width joiner U+200D passes where it joins two pictographs, as in an emoji built from several (a person at a laptop, a family, the rainbow flag): the character before it is a pictograph, or a VS16 right after one, and the character after it is one. The three subdivision flags (England, Scotland, Wales) are built from tag characters and stay refused, and so does the zero-width non-joiner U+200C, which some scripts’ words (Persian, several Indic scripts) carry. They render as nothing but reach an agent intact, so the error names them by code point: must not contain invisible characters (U+200B); retype the text without them. A security’s name is the one exception: its format characters are dropped as it is stored, as before, and only a run of variation selectors is refused. Anything else answers 422 naming the field, never a server error. A Portfolio Performance import names a row whose names or note break the same rule in its preview. A security’s free-form attributes map meets the rule at any depth: every key is one-line text of at most 255 characters, and every text value, in a nested object or list too, is free text; otherwise the write answers 422 on attributes. The map as stored, merged with the attributes already there, is at most 65536 bytes as compact JSON; a write that would pass that answers 422 on attributes and stores nothing. An update that changes nothing writes no row and leaves no journal entry. A search provider’s property that breaks the rule is dropped before it reaches the attributes. A read’s text filter — the securities query, the journal’s resource_type and resource_id, the tax reads’ holder, institution and jurisdiction — is one-line text of at most 255 characters; anything else, a list included, answers 422 naming the parameter.

Wrapped bodies. A write whose attributes travel under one key — {"transaction": {…}}, {"view": {…}}, {"rule": {…}} and their siblings — answers 422 naming that key when its value is not a JSON object (a string, a number, a list).

Delta reads (FR-38). The two recurring-sync reads — GET /api/v1/transactions and GET /api/v1/securities — accept ?since=<ISO8601> (a datetime with offset, a naive UTC datetime, or a plain date meaning start of that day, UTC) and then return only the rows created or updated strictly after that instant, judged by updated_at. The response echoes since, carries as_of — use it as the next since — and a delta_note stating the semantics. as_of lies one second before the read instant, or before the start of the oldest transaction that has written and is still open, whichever is earlier: a row is stamped when its transaction writes it, not when that transaction commits, so a cursor at the read instant would skip a row a long write (an import) commits after the read. The next read may therefore re-deliver a row, but never skips one. Deletions are not represented in a delta read; a caller that must detect deletions performs a full read. An invalid since is a 422. Delta reads are pull-only: push delivery (webhooks to a user-configured endpoint) is a separate, still-gated decision (B3.7) and deliberately not part of this surface.

Which reads carry since (issue #830, Sprint 14 D-5). since is a row-delta parameter, so it fits reads that answer a collection of rows with a change stamp, and only those. The family splits three ways:

Carries it — the row collections a scheduled run polls: GET /api/v1/transactions, GET /api/v1/securities, GET /api/v1/securities/:security_id/notes (by inserted_at: the research log is append-only, so an entry never changes after it is written; the derived thesis_state still covers the whole log), GET /api/v1/securities/:security_id/events (by updated_at, so a rescheduled date returns as its changed row), and GET /api/v1/portfolios/:portfolio_id/targets and /position_targets (a target row counts as changed when it or its plan changed after the cut — activating another plan version swaps the steering rows without editing any of them; the position read’s effective_targets roll-up always covers the whole plan, and min_drift applies after the cut). Their MCP twins take the same since string: portfolixir.transactions.list, portfolixir.securities.list, portfolixir.notes.list, portfolixir.events.list, portfolixir.targets.list and portfolixir.targets.list_positions. The configuration collections (portfolios, cash and securities accounts, buckets, views, classifications, plans, tax parameters, profiles and allowance orders, snapshots) do not carry it: they are small and operator-edited, and several carry per-row figures derived from other tables (a cash balance, a statement’s staleness) that move without the row’s updated_at moving.
Derived projections do not carry it — and need a different mechanism: valuation, allocation, performance, benchmark, income and risk have no rows and therefore no updated_at. “Has the valuation changed since I last read it” is a question about the version of its basis, which the instance already tracks internally (ADR-0039) but does not expose; answering it is a conditional-read mechanism (an ETag or a basis token) that has not been built.
Time-derived queues must not carry it: /notes/unreviewed, /notes/expiring, /notes/uncorroborated, /events/upcoming, /events/stale and /events/unconfirmed. Their membership changes because time passes, with no row changing — a position becomes unreviewed overnight, a date enters the horizon. A cut on updated_at would silently drop exactly the rows a poller needs, so these reads ignore since like any parameter they do not define (full answer, no delta envelope), and their MCP tools do not accept it.

The human view of the same cut (issue #731) lives on /transactions?since= and /securities?since= as the Changed since chips: same parameter name, same accepted forms, same strictly-after-updated_at cut, so a link an agent hands over opens exactly the slice it read. The one divergence is deliberate: where the API rejects an invalid since with a 422, the pages degrade to the unfiltered list — a stale bookmark must never silently narrow what the operator sees.

Securities

The data_quality predicates are the same rule the dashboard counts and the securities page links to (issue #705): they are defined once in Portfolixir.Catalog.DataQuality, so a count of N always addresses a list of N, and an agent asking “which securities have a stale quote” gets exactly the set a person sees. Combine them with query, holding_status and the other narrowings; an unknown value is a 422 naming data_quality, never a silent full list.

GET /api/v1/securities lists securities. Rows default to a slim projection — the fixed whitelist id, name, ticker_symbol, isin, wkn, currency_code, asset_class — so routine listings stay small; projection=full returns the complete record (notes, feed config, attributes, timestamps). An optional fields= (issue #732, extending FR-37, comma-separated) selects a sparse fieldset resolved against the full projection’s field list; a present fields= supersedes projection=, because a sparse fieldset is itself a projection, chosen field by field. An unknown name is a 422, never a silent fallback. Optional query params: query, sort, direction, holding_status (all, held, or not_held), logo_status (missing or present — the bare logo condition; missing excludes rows explicitly set to no logo and includes a stored logo whose file is gone, whatever its lock, issue #933; present is a stored logo whose file is not), data_quality (stale_quote — no quote newer than 7 days, including securities never priced at all; missing_quote — no quote at all, the narrower set inside it; missing_logo — no stored logo and not set to no logo, or a stored logo whose file is gone (file_missing on the logo read), the set the “securities without a logo” overview shows; missing_fx — issue #717: priced, but with no stored rate from its currency to the EUR hub, so storing the rate empties the set. A benchmark and a retired security are in none of the first three, which leave them out in the query, before limit/offset: retiring a sold-out or delisted security takes it out of all three, and reactivating it puts it back in those it matches. missing_fx keeps both; two_scales — issue #1068: every bond the two-scales guard names, in either direction, catalog-wide, the set the Overview’s data-quality line counts; see bond.two_scales below for the rule and which securities count as bonds. It keeps a benchmark and a retired security too, since their figures are as wrong as before; implausible_quote — issue #1101: every held security for which a buy, a sell or a priced inbound delivery has a stored quote, on the booking’s date or the latest within 7 days before it, below half or above twice the booking’s price per unit in the security’s currency (a booking in another currency at its security_amount ÷ quantity), read on the booking’s split basis (ADR-0028 §2), so a recorded split is not named and an unrecorded one is; a booking at a price of 0, or with no quote in the window, is not compared, and a security two_scales names is not counted again. It is the set the Overview’s data-quality line counts, and keeps a held benchmark or retired security. Under it the envelope adds findings, one per listed security — security_id, kind (buy, sell or inbound_delivery), date, price, currency_code, quote_date, close (on the booking’s split basis), ratio (close ÷ price, rounded half up at scale 6) and bookings_outside, the latest booking outside the band being the one named — and computation_basis, which states input_series, reference, window, gaps, threshold and assumptions), projection (slim/full), and limit/offset for pagination (both non-negative integers). Use these to page large catalogs instead of fetching the whole table at once. A data_quality set is filtered before limit/offset page it, so only its last page is short (issue #1113). The human view of these narrowings is the one-tap filter-chip row on the securities page (issue #717): its chips ride the same URL state (holding=, dq=, filter[]=asset_class:is_nil, plus cur[]= and class[]= for the currency and effective-class families), so a pre-filtered link and an API read describe the same set. is_benchmark=true narrows the read to the securities flagged as benchmarks (ADR-0046: the reference series of the benchmark comparison), is_benchmark=false leaves them out; the flag is a field of the full projection and of fields=, and POST/PATCH accept it. is_retired=true narrows the read to the retired securities (issue #1103), so a security retired out of the hygiene sets is found again and restored with PATCH {"security": {"is_retired": false}}; is_retired=false leaves them out. Both flags take true or false (blank counts as absent, anything else is a 422 naming the flag) and narrow together with the other parameters: beside a data_quality set that leaves such securities out, is_retired=true or is_benchmark=true matches nothing. Held (holding_status=held, and every other held filter: the research log’s unreviewed positions and the events’ held_only) means one thing: a non-zero net quantity across all depots, moved by buy, sell, inbound_delivery and outbound_delivery — a depot transferred in is held the moment it arrives; a security_transfer between own depots nets to zero.
POST /api/v1/securities creates a security with a security object. asset_class is a stable string code: equity, etf, fund, government_bond, bond, crypto, commodity, index, other, plus the certificate/leverage codes warrant, knock_out, factor_certificate, discount_certificate, bonus_certificate, express_certificate, reverse_convertible. Leave it empty to let the class be inferred from the name/ISIN/ticker on read. To keep a position out of the allocation steering basis (the 100%) and the drift table while leaving it in the valuation totals and performance — e.g. a Bitcoin held as a store of value — tag it with a bucket and exclude that bucket from a view, then read allocation under that view.
GET /api/v1/securities/:id returns one security, including its identifier_aliases — the former ISINs recorded via the ISIN-change endpoint below (each with id, former_isin, changed_on, note) — and its thesis_state, the current thesis derived from the research log (see below). Listings carry thesis_state as null; only the detail read computes it. A security a merge took away answers 404 with errors.merged_into {"kind": "security", "id": …}, the security its history lives on now — followed through every later merge to the live one — and a detail naming both (ADR-0050 §12); an id no merge names answers the plain 404, and so does one whose chain ends at a row deleted since (a survivor may be deleted once it holds nothing), without merged_into and with a detail naming that row. Every route under /api/v1/securities/:security_id/ answers a merged-away id the same way — the quotes, trades, metrics, notes, events and logo reads, their writes, the ISIN change and the delete of an identifier alias.
PATCH /api/v1/securities/:id updates a security with a security object. The boolean treat_quotes_as_raw (default false) is the ADR-0028 escape hatch for providers that never back-adjust their history after a stock split: with the flag set, the security’s provider-synced quote rows are treated as raw (as-traded), so the split-adjustment factors apply to them too. The boolean is_retired retires a sold-out or delisted security, and false restores it: a retired security leaves the stale_quote, missing_quote and missing_logo sets, and its stale quote stops counting as a price measurement in performance, which can restate its TTWROR history (#610). Like every security update, it is journaled under the calling token. A security’s currency_code freezes once it has a transaction or a quote (ADR-0050 §11): a change then answers 422 with errors.currency_code counting them, for example ["is frozen once referenced (120 quotes, 3 transactions)"], and nothing is written. Resending the stored currency is no change, and the other fields stay editable.
DELETE /api/v1/securities/:id deletes a security when nothing references it. A policy rule that reads it answers 409 Conflict with errors.policy_rules. Bookings, quote history, research notes, security events or policy-rule versions answer 409 Conflict with errors.referenced_by (the referencing tables, counted, for example {"transactions": 3, "security_quotes": 120}), errors.remedy and errors.remedy_route: merge for a duplicate, whose route is the merge preview GET /api/v1/securities/:id/merge_preview?target_id= completed with the id of the security to keep, or retire when research notes or rule versions reference it, because a merge cannot carry them (the route is PATCH /api/v1/securities/:id with is_retired: true). Before an unreferenced security is deleted, its category assignments, position targets, position bucket overrides and ISIN aliases are removed, each journaled; no database cascade removes them (ADR-0050 §11). A security that is already gone answers 404. A delete that loses a race to a concurrent write, with nothing referencing the row afterwards, answers 409 Conflict with errors.detail alone and deletes nothing: read the row again and retry (#954).
GET /api/v1/securities/search searches configured online security providers. Query params: query; optional type with security or crypto. Every field of a hit comes from the provider and is checked for its type and bounded in size: a field of the wrong type or over its bound is absent, a hit without a usable name is dropped, a market keeps only bounded fields and scalar properties, and raw carries only type and market_cap_rank, never the provider’s whole entry. The attributes a hit writes to a security are bounded the same way, and a name or quote-feed URL longer than 255 characters is a 422 on any security write.

ISIN changes (identifier aliases)

When a corporate action gives an existing security a new ISIN, record the change instead of editing the ISIN in place: the former ISIN becomes a journaled alias, and the import’s ISIN matching consults current ISINs first, then the aliases — so re-imports of old exports (former ISIN) and new exports (new ISIN) both keep matching the same security instead of duplicating it (ADR-0029). A plain rename needs no ISIN change — it is just a name edit.

POST /api/v1/securities/:security_id/isin-change records the change with an isin_change object: required new_isin (normalized to trimmed uppercase), optional changed_on (ISO date, defaults to today) and note. Returns the updated security including its identifier_aliases. A new_isin that is not twelve characters of the ISIN shape (two letters, nine letters or digits and a check digit) or whose check digit does not agree answers 422 on new_isin, and a note over 255 characters 422 on note. Guarded with 422 and a named conflict when new_isin equals the current ISIN, is live on another security, or is recorded as another security’s former ISIN; recording a change back to one of the same security’s own former ISINs consumes that alias (a revert). Every security-ISIN write path — create, update, and the import’s create path — symmetrically rejects an ISIN that exists as an alias, naming the aliased security. A conflict names the other security by its id (security #12), never by its stored name (see “A record named in a sentence” below).
An identifier changed on an existing security through PATCH /api/v1/securities/:id meets the same catalog rules, or answers 422 naming the field: an isin of the ISIN shape with a check digit that agrees, a wkn of six letters or digits, a ticker_symbol of printable ASCII only. A lookalike (a letter from another script, an invisible character, a wrong check digit) never replaces the identifier the exports carry. Resending the stored value is no change, and a new security keeps what it is created with. A security’s name is stored without Unicode format characters (zero-width spaces and joiners, bidirectional controls).
DELETE /api/v1/securities/:security_id/identifier_aliases/:id deletes one recorded alias (journaled) when an ISIN change was recorded by mistake; returns 204 No Content, or 404 when the alias does not belong to the security.

Example ISIN-change payload:

{
  "isin_change": {
    "new_isin": "IE000XZSV718",
    "changed_on": "2026-07-01",
    "note": "merger rename"
  }
}

Merging a duplicate security (ADR-0050 §9)

A second copy of one instrument — an export carrying a newer ISIN imported before the change was recorded, a security created by hand that the next import created again — is repaired by merging the duplicate (the source) into the security you keep (the target). The operator’s dialog on the securities page (the row menu’s Merge into…) reads this preview and confirms with the same plan_digest, so both see the same plan.

GET /api/v1/securities/:id/merge_preview?target_id= previews merging the security into target_id — a read that writes nothing (portfolixir.securities.merge_preview). Both must trade in the same currency, be both or neither a benchmark, and the target must not be retired while the source is live; while the source has quotes, both must treat their synced quotes alike (treat_quotes_as_raw). A source with research notes or read by a policy rule is refused, because a note can neither move nor vanish and a rule version keeps its subject (research_notes, policy_rules with errors.policy_rules); where merging the other way would pass, the detail says so. Each position the source holds in a depot must keep its view membership (position_buckets_mismatch). A split of the source the target carries in the same portfolio on the same day with the same ratio collapses; another ratio is refused (split_ratio_mismatch), and so is a split one side lacks while that side has a booking or a quote before it (split_event_mismatch) or a split that would rescale bookings it did not scale before (split_linearity), or a split the merge would move that still carries an import hash from a re-type before the import-hash kind check (legacy_hashed_split, with errors.splits; change its kind back or delete it — one the merge collapses is deleted with its hash retired). A source ISIN that fails its check digit is refused (invalid_source_isin): the merge would write it onto the target, which the catalog refuses for a stored security, so correct or clear it on the source first. Finally, every identity of both securities must still find the target after the merge (identity_unresolvable, with errors.unresolvable): the identity as stored, the identity the Portfolio Performance import recorded when it created the security (its name, ISIN, WKN, ticker and currency — a file resolves on what it carries, not on identifiers added since), each former ISIN, and, for every security merged into either of the two before (and into those, down the chain), its identity as stored and as imported (merged_stored, merged_imported, under the merged-away security’s id): a survivor merged away in turn must still lead every earlier import to the history. A name-only security that was given a ticker after its import and whose name differs from the target’s is such a case; so is a name that another live security also carries. Each refusal is a 409 Conflict with errors.code, errors.detail and errors.guards; an unknown source answers 404, a source already merged 409 already_merged with errors.merged_into, a missing target_id 422. The 200 carries:
- plan_digest, the digest the merge takes;
- source and target, each with its name, currency, isin, wkn, ticker_symbol, feed, asset_class, flags, transaction_count and split_events; guards; reverse, whether merging the other way would pass;
- key_equal_pairs and choice_required, as for an account merge, and splits (collapsed, moved) with split_events before and after;
- position_buckets: per depot the source holds or carries an override in, both effective bucket sets, both overrides and the action;
- quotes: source_count, moved_count (the source’s quotes on dates the target has none, which move keeping their source), collision_count (dates both have: the target’s quote wins, the source’s close goes into the merge record) and manual_collisions, each colliding source quote typed by hand, with date, source_close, target_close and target_source;
- configuration: category_assignments (per classification of the source, move where the target has none in it, otherwise drop — the target’s wins — with both categories) and position_targets (every position target of the source in an active, draft or archived plan, with its plan, plan_status, category and target_weight, and move, or drop with the reason collides — the target has a row in that plan — or stale — the row would no longer sit under the target’s category);
- events: the events that move, and possible_duplicates, a source and a target event of the same kind on the same day (both kept);
- identifiers: choice_required (both carry an ISIN), then after_by_identity_choice with keep_target_isin and adopt_source_isin — or after when there is no choice — each the target’s isin, wkn, ticker_symbol, feed, name, asset_class and former_isins after the merge; adopted, what the target takes from the source (a WKN, ticker or feed it lacks, an ISIN only the source carries); differences, every source value that follows the target instead (name, asset class, logo, a WKN, ticker or feed the target has already, and a WKN or ticker the catalog’s rules refuse on a change, which is never adopted and lists the target’s null); aliases_reassigned, the source’s former ISINs;
- outcome_by_collapse_key_equal with "false" and "true": the target’s transaction_count after, moved_transaction_ids, deleted (collapsed_duplicate or collapsed_split), positions (per depot the source holds: source, target and after, each quantity, cost_basis, avg_cost and realized_result), rounding_differences, cash_accounts and flow_changes, with positions_basis as for a depot merge; reimport_note says what the merge does to the next import.
Every quantity, close, weight and decimal is a string. The digest covers both securities, every booking of either, their quotes, category assignments, position targets, events and former ISINs with their updated_at, the identities the imports recorded, every figure and the guards; the choices are not part of it, so one pair has one digest, and a quote the sync stores between the preview and the merge is a changed plan.
POST /api/v1/securities/:id/merge with {"target_id": …, "plan_digest": …, "collapse_key_equal": …, "identity_choice": …, "isin_changed_on": …} merges under the token (portfolixir.securities.merge). collapse_key_equal is required when the preview lists key_equal_pairs, and identity_choice when both securities carry an ISIN — each a 422 without it, and never preselected: ask the operator. keep_target_isin keeps the target’s ISIN and records the source’s as a former ISIN of the target; adopt_source_isin gives the target the source’s ISIN and records the target’s old one as its former ISIN (the repair of ADR-0029 §3’s wrong-order duplicate, together with collapse_key_equal: true). isin_changed_on (YYYY-MM-DD, optional) is that former ISIN’s changed_on; the merge date otherwise. An unknown identity_choice or an isin_changed_on that is no date answers 422. It answers 201 Created with the merge record (kind security, portfolio_id null; its manifest lists every booking moved or deleted, every quote moved and every quote dropped with its close and the target’s close that won, the assignments, position targets and events moved or dropped, the former ISINs reassigned and created, the identifiers adopted and the differences, and the choices — collapse_key_equal only where the preview listed key_equal_pairs, identity_choice and isin_changed_on only where the merge made that choice, both securities carrying an ISIN, and null otherwise, whatever the request sent) and already_applied: false. In one transaction, one audit-journal entry per row: with true the source’s paired bookings are deleted and their content hashes retired; a split the target carries on the same day in the same portfolio is deleted; every other booking moves onto the target; the quantity of every depot is checked on every day against the fold of both securities’ bookings (409 identity_check_failed otherwise); the bucket plan is written; the quotes are gap-filled — not journaled, the merge record is their record — and both securities’ derived values are invalidated; the assignments, position targets and events move or are dropped as the preview listed; the source’s former ISINs go to the target, its ISIN is written by the choice, its WKN, ticker and feed where the target lacks them; the source is deleted; and the identities are checked again on the catalog as the merge left it (409 identity_unresolvable with errors.unresolvable rolls it back otherwise). After it, a Portfolio Performance import naming the source by any of its identifiers books onto the target, and a re-import of an export already applied creates nothing. A changed plan answers 409 plan_changed with the fresh preview in errors.preview; a retry of a completed merge of the same pair answers 200 with the original record and already_applied: true; a source merged into another security 409 already_merged. There is no unmerge.

Research log (ADR-0044)

What the operator or the agent knows about a security is recorded as append-only dated entries — the security research log — and the current thesis state is derived from them, never maintained beside them. Entries are never updated and never deleted: a refuted finding is withdrawn by appending a retraction that supersedes it, and both stay readable, so the next run sees the retraction first instead of re-investigating a settled premise. There is deliberately no PATCH and no DELETE for an entry.

Each entry carries kind (thesis, evidence, invalidation_check, event_result, risk, retraction, decision), body, source_url (an http(s) URL of at most 255 characters; other schemes and longer links are a 422), source_quality (primary, secondary_multi, awareness, unverified — set, not guessed), as_of (the statement’s cut-off date, distinct from inserted_at: an entry written today about last quarter carries last quarter’s date), author (operator, agent, local_model; the API defaults to agent), machine_generated (an extracted entry is a proposal until confirmed and must carry its source_url), supersedes_id (the earlier entry of the same security this one replaces; required for a retraction), valid_until (a dated block such as a lockup or a self-imposed buying block), and — on thesis entries only — conviction (low, medium, high), invalidation_condition and time_stop. Every entry in a response also carries superseded_by_ids and a superseded flag, so a superseded entry is shown as superseded rather than hidden. All closed sets are validated; an unknown value is a 422 naming the field, and no atom is ever created from input.

GET /api/v1/securities/:security_id/notes — the log, newest first (by as_of, then write time), with the derived thesis_state and a log_note stating the append-only contract. limit keeps the newest entries (default 1000, max 10000); thesis_state always derives from the whole log, and the answer echoes the applied limit.
POST /api/v1/securities/:security_id/notes — appends one entry from a note object (201); journaled under the API-token actor. An as_of after today (the instance’s calendar day) answers 422 on as_of (“must not be in the future”): the log is append-only, so a mistyped future year could never be taken back. valid_until and time_stop may lie in the future. body holds at most 20000 characters and invalidation_condition at most 10000 (Unicode code points); a longer value answers 422 naming the field, and the database refuses it as well.
GET /api/v1/notes/unreviewed?days=N — held securities (net quantity non-zero across all depots) whose newest entry is older than N days (default 90) or that have none; rows carry last_entry_as_of and days_since_last_entry (null when never reviewed). An entry counts as a review on its as_of, but no later than the day after it was written, so an entry stored with a future as_of before the refusal existed cannot keep its position off this read; the thesis state’s last_reviewed_at follows the same rule, and the entry itself keeps its as_of. limit keeps the most overdue positions (default 1000, max 10000).
GET /api/v1/notes/uncorroborated — entries whose source_quality is not primary, newest first; superseded entries are skipped unless include_superseded=true; optional security_id. limit keeps the newest entries (default 1000, max 10000).
GET /api/v1/notes/expiring?days=N — entries whose valid_until falls within the next N days (default 30), soonest first, with days_until_expiry; lifted (superseded) blocks are skipped; optional security_id. limit keeps the soonest-expiring entries (default 1000, max 10000).

The thesis state (thesis_state on the security detail and on the log read) is the B4.1 projection: status (none, intact, retracted), the current thesis text, conviction, invalidation_condition, time_stop, as_of, last_reviewed_at and last_reviewed_by (the newest thesis or invalidation_check entry), derived_from_entry_id (the thesis entry it reads from) and retracted_by_entry_id (the retraction whose body carries the reason), plus a basis sentence stating the derivation. The newest thesis no other thesis supersedes is the current one; a retraction superseding it sets retracted.

Example append payload:

{
  "note": {
    "kind": "retraction",
    "body": "Checked the 10-Q on 2026-08-02: no supplier dispute disclosed. Withdrawn.",
    "source_url": "https://example.invalid/sec/10-q",
    "source_quality": "primary",
    "as_of": "2026-08-02",
    "supersedes_id": 41
  }
}

The human view is the Research tab of the security detail pane on /securities/:id: the thesis state on top, the entries newest first with kind and source quality visible, superseded entries marked as such, retractions legible, and a form that appends an entry as the operator.

Security events (ADR-0048)

A security event is a dated statement that something will happen, or has happened, to a security: an earnings report, an ex-dividend or payment date, a lockup expiry, an index review, a shareholder meeting, a regulatory decision, a guidance update.

It is not a corporate action. A split changes a position and is therefore a ledger event (ADR-0028); an earnings date changes nothing until a price moves, and a price move is already a quote. security_events is its own table and the ledger projection never sees one. When the calendar fact becomes a booking — the dividend is actually paid — the booking goes through the ledger as it always did and the event is marked confirmed: the event is never converted into a transaction and the transaction does not consume it.

The catalog, not the holdings. Events key on security_id and nothing else — no portfolio, no depot, no view — and the catalog-wide reads cover every security by default. held_only=true narrows them and is never the default. This is the requirement rather than a query detail: a calendar derived from the position list cannot hold a date for a security not yet owned, which is exactly the security whose dates matter most.

A date is qualified by how well it is known. timing is one of exact (a source that sets it), estimated (expected rather than announced), window (between date and date_end, inclusive — date_end is required here and allowed nowhere else) and month (the month of date is known, the day is not). “Earnings expected late February” is not a date, and storing it as one makes a guess indistinguishable from a filing.

Mutable and journaled, deliberately not append-only. A research entry is an argument whose history is its meaning; an event is a fact about the world, and a rescheduled call does not make the old date a second fact — it makes it wrong. So a correction is a PATCH on the same row, and the change history lives in the append-only audit journal.

The reads:

GET /api/v1/securities/:security_id/events — one security’s events, soonest first, with limit (default 1000, max 10000).
GET /api/v1/events/upcoming?days=N — everything due within N days (default 30) across the whole catalog, soonest first. A window or month event is due when any day it could fall on is inside the horizon — the conservative direction, because the failure being prevented is a missed date rather than an early warning. Optional kind, held_only, limit; the answer echoes days, as_of, held_only and its scope. days is bounded the way limit is: a value above ten years is capped and echoed capped.
GET /api/v1/events/unconfirmed — events whose whole span is in the past and whose confirmed flag is still false: the “did it actually happen?” queue, which is what keeps the calendar from quietly rotting. Optional security_id, kind, held_only, limit; there is deliberately no days here, because an unconfirmed past date belongs in the queue however old it is.
GET /api/v1/events/stale?days=N — events whose checked_at (the day the fact was last re-read against its source) is older than N days (default 90), or that were never checked at all, which are listed with days_since_checked null. Deliberately a different read from the one above: a confirmed future date nobody has re-read in three months is a different risk from a past date nobody resolved. An event whose stored checked_at lies after tomorrow (written before the refusal below existed) is listed too, with a negative days_since_checked.

The writes:

POST /api/v1/securities/:security_id/events — records one event (201). security_id comes from the path, never the body; machine_generated is reserved and is ignored in the body.
PATCH /api/v1/security_events/:id — corrects or confirms one in place. The security it belongs to cannot be changed.
On both writes a checked_at later than tomorrow (the instance’s calendar day plus one day of zone slack) answers 422 on checked_at and writes nothing: it is the day the source was re-read, and a future one would hide the event from the stale read. An event’s note holds at most 10000 characters (Unicode code points); a longer one answers 422 on note.
DELETE /api/v1/security_events/:id — removes one (204), journaled with the row recorded, for a duplicate or a date that never existed. To record that a date passed, mark it confirmed instead.

source_quality reuses the research log’s vocabulary exactly (primary, secondary_multi, awareness, unverified) — one scale for “how well do we know this” across both knowledge families. An event carries no money: there is no financial decimal on the object at all.

What this surface is not. Nothing fetches a calendar — entry is manual or through the agent’s own write. The due-date read is a pull: there is no alerting and no push delivery. No rule reads these rows, and whether events predicted anything is not evaluated here.

Derived metrics (ADR-0047)

Scope-ladder level (a): one security’s price metrics, derived on read from the quote history it already holds. Nothing is stored and nothing is fetched.

GET /api/v1/securities/:security_id/metrics — sma_50 and sma_200 with the latest close’s distance_pct to each; volatility and max_drawdown over the windows 30d, 90d and 365d; momentum over 3m, 6m and 12m; distance_to_extremes, the 52-week high and low with their dates and the distance to each. The drawdown carries peak_date, trough_date and recovery_date (null while the series is still below the peak). Optional as_of (ISO date, default today) bounds the series: closes dated after it are not read. An unknown security is a 404; a malformed as_of a 422.

Three properties are worth knowing before comparing two securities.

The series is the security’s own. Metrics read the stored closes in the ADR-0028 §2 display basis (split-adjusted at read time; the stored rows are never mutated) and in the security’s own currency — deliberately not converted to the base currency, because a price metric is a statement about the instrument and a conversion would fold the FX path into it.

A gap produces no observation, never a zero. Returns are taken between consecutive stored closes; a day with no close is not carried forward and then differenced, because that manufactures a calm 0 % day and drags the standard deviation toward zero. Every metric therefore carries its observations count and the window it was measured over, and the payload carries computation_basis (input_series, window, reference, gaps, assumptions) once.

Below its minimum a metric refuses. value is null with insufficient_data: true and the observation count it had, at 200 — a gap marker, not an error: 20 return observations for a volatility, n closes for an n-day moving average, 2 closes for a drawdown, and a close on or before the window’s start for the momentum and the 52-week extremes. A volatility whose square root lies beyond what the one float step can carry — a magnitude only implausible stored closes reach — is null without insufficient_data: undefined, not short of data, and never an error.

Every metric says what it needed (ADR-0047 §6 as amended 2026-09-19): required carries the minimum observations on every metric, whether it computed or refused — n for sma_n, 20 for volatility, 2 for max_drawdown and momentum, 1 for distance_to_extremes — so a reader comparing two payloads finds the threshold without knowing which state they are in. For the momentum and the extremes the integer is the count floor only; the coverage rule (a close at each end of the window) stays in computation_basis.gaps. A refused sma_n renders window: null: its span is an output of the newest n closes, and below n there is none.

Volatility is the population standard deviation of the window’s simple daily returns, annualized by √252; distances, momentum and volatility are ratios rather than percentages (0.05 is +5 %), rounded at scale 6.

This surface reports; it does not evaluate. There is no signal, no recommendation, no rating, no score and no action in the payload — an SMA-50 above an SMA-200 is two numbers and a distance. A rule over a metric is FR-43 and is gated; backtesting one is out of scope. A meta-test walks the rendered key set so the boundary holds mechanically.

Bonds: master data and the bond reading (ADR-0052)

A bond’s master data is six nullable fields of the security, settable with POST /api/v1/securities and PATCH /api/v1/securities/:id and answered by every security payload (and selectable with fields=):

coupon_rate — the coupon in percent of face per year, a Decimal string from 0 to 100 ("2.5", not "0.025");
coupon_frequency — annual or semi_annual;
maturity_date and issue_date — ISO dates, the maturity after the issue date;
face_value — the denomination, a Decimal string above 0;
face_value_currency_code — the denomination’s currency, an ISO 4217 code from the set currency_code takes.

coupon_rate and face_value keep 6 decimal places, under the rule every stored amount follows (Other stored amounts above): a finer value is rounded half up before it is checked, so "3.1234567" is stored and answered as "3.123457". Send them as strings, as every decimal; a JSON number is cast the way every decimal field casts one.

null clears a field, nothing is required, an impossible value is a 422 naming its field with nothing written, and the fields are kept when the asset class changes. They are read while the effective asset class is bond or government_bond, and — since issue #1068 — while the security has no asset class, stored or inferred (its asset_class is null and the name and logo rules infer none), carries a maturity_date or a coupon_rate, and has a name the inference does not read as a structured product’s: the name inference recognises government-bond names and, since issue #1127, the explicit bond words (Anleihe, Schuldverschreibung, Pfandbrief, Notes, Obligation), so that master data is what marks a corporate bond named without one and without a class as a bond. A security with any other class, stored or inferred, is no bond, whatever master data it carries; a bond whose name carries its issuer’s legal form and no bond word is stored as equity on create, as is one with a bond word stored before issue #1127, and needs its asset_class set to bond. The MCP tools portfolixir.securities.create and portfolixir.securities.update take them (the update also null).

GET /api/v1/securities/:id of such a security carries bond, computed on read and never stored (scope-ladder level (a)); it is null for any other security and on listings and write responses:

as_of and quantity (the units held across every depot);
nominal_held — amount, quantity × 100, in currency_code (the face value’s, else the security’s): a Portfolio Performance export books a percent-quoted bond’s quantity as a hundredth of its face amount, so a quote is both percent of face and the price per unit;
remaining_term — days from as_of to the maturity, years (days ÷ 365, rounded half up at scale 6), whole_years and whole_months, matured on and after the maturity date;
current_yield — coupon ÷ price, and yield_to_maturity — the linear approximation (coupon + (100 − price) ÷ remaining years) ÷ price, without compounding; each a ratio rounded half up at scale 6 (0.025707 is 2.5707 %), sent without trailing zeros like every decimal ("0.03685", "0"), with the price it used (value, date, source: quote for the latest stored quote, trade for the last own trade price while there is none);
two_scales — null, or the finding that the bond is priced on two scales: its direction, its latest_quote, the count of unit_scale_bookings and the last_unit_scale_booking, and the rule.
- direction: "forward" — a latest quote 20 to 500 times a booked price per unit (a buy’s or a priced inbound delivery’s): quotes near 100 beside bookings near 1. Every money figure of such a bond is a hundred times too high, and the TTWROR does not show it.
- direction: "reverse" (issue #1068) — a latest quote 1/500 to 1/20 of a booked price per unit, both ends included, and itself at most 5: quotes near 1 beside bookings near 100. The stored quotes are not percent of face, and the bond counts a hundred times too low in every total.
The two booking keys keep their names in both directions and hold the bookings inside the band; where a bond has bookings in both bands, the forward finding is reported. The rule states both bands and which securities are read as bonds. Nothing is converted, in either direction.

Every metric carries its own computation_basis (input_series, window, reference, gaps, assumptions). A figure without its input is null with insufficient_data: true and the inputs it lacks in missing (coupon_rate, maturity_date, price); a matured bond’s yields are null with matured: true. A yield whose price is the last own trade price at at most 5 — the two-scales band’s mirror, 100 ÷ 20, the price per unit of a booking that recorded the nominal as the quantity — is null with price_on_unit_scale: true, neither insufficient_data nor matured: such a price is not percent of face, so coupon ÷ price would be no yield. A stored quote is a percent price at any level and is always used; price_on_unit_scale is false on every other yield. Accrued interest, fees and taxes are excluded; the reading reports, it does not evaluate.

Logos

Each security can carry a logo, resolved automatically (CoinGecko for crypto, Wikipedia and then companieslogo.com for equities/ETFs/funds, the issuer’s logo for a structured or leverage product) or set manually. A manual logo, or an explicit “no logo”, locks the security so background discovery never overwrites the choice.

GET /api/v1/securities/:security_id/logo returns the logo status: { "data": { "security_id", "path", "source", "has_logo", "locked", "file_missing" } }. source is one of coingecko, wikipedia, companieslogo, or manual, and null while there is no logo. file_missing (issue #933) is true when the instance’s startup check found no file in the logo directory for the stored path; has_logo is then false, while path, source and locked read as stored. A discovered logo so marked is looked up again; a manual one stays locked and waits to be set again, and logo_status=missing and data_quality=missing_logo list both. Storing or removing a logo clears the mark, and so does the next start once the file is back.
PUT /api/v1/securities/:security_id/logo sets a manual logo from an image URL ({ "logo": { "url": "https://…" } } or { "url": "https://…" }). The image is downloaded once, validated (png/jpg/jpeg/webp, max 256 KiB) and stored locally; the security is locked to the manual choice. A missing URL returns 422 with errors.url; an image that cannot be fetched or fails the check returns 422 with errors.logo, a fixed message that names no address and no status.
DELETE /api/v1/securities/:security_id/logo removes the logo and records an explicit “no logo” decision (the row falls back to its initials/flag), also locking it against discovery.
POST /api/v1/securities/:security_id/logo/discover re-runs automatic discovery (“search again”). The response includes a result of updated, no_source, or failed. Locked securities are left untouched and answer no_source.

Quotes

GET /api/v1/securities/:security_id/quotes lists quote history for one security. Optional query params: from and to, formatted as ISO dates. Invalid date filters return 422 Unprocessable Entity with field errors. Each row is self-describing about stock splits (ADR-0028): close is the stored value (never mutated), adjusted_close the split-adjusted display value, basis the row’s storage basis (raw for as-traded manual rows, provider_mirror for back-adjusted sync rows) and adjusted whether a split factor applied. Chart or value with adjusted_close; audit against close. A security whose provider never back-adjusts can be flagged with treat_quotes_as_raw (see Securities), which forces the raw basis for its synced rows. limit keeps the newest rows of the window, still ascending (default 20000, max 50000; zero, negative or non-numeric is a 422).
PUT /api/v1/securities/:security_id/quotes upserts manual quote rows. Every row is stored with source manual, whatever source it names: a close written over the API is a manual close, and the provider sources are the quote sync’s to state. A manual close wins over provider data, so the write replaces a stored row of any source for its dates, and the sync leaves a manual row alone until it is released (below). The write is journaled under the token (resource_type=security_quotes, filed under the security’s id, operation upsert) with the stored rows it replaced — their closes and sources — as the before-image. The answer is {"upserted": n, "replaced": [dates]}: upserted counts the rows now stored as given, and replaced lists the ISO dates whose stored row the write changed (a new date is not listed). A write that changes nothing leaves no journal entry. Every quote row, manual or synced, is bounded: a close that is positive once rounded to its 6 decimal places, with at most 14 digits before the decimal point, on a date no later than tomorrow (the instance’s calendar day plus one day for time zones). A row outside the bound answers 422 naming the field, and a sync drops such a provider point instead of failing the run. The latest-quote reads (the valuation price, the catalog’s latest price and the stale-quote check) never use a stored row dated past the bound. One batch names each date once and carries only quote objects: a repeated date answers 422 with errors.date naming it, a row that is not an object 422 on quotes, and nothing is written.
POST /api/v1/securities/:security_id/quotes/release releases the security’s manual quotes dated from through to (both required, inclusive, in the body or the query) back to provider data: the manual rows in the range are removed, journaled under the token (operation delete) with the released rows as the before-image, and the answer is {"security_id", "from", "to", "released": [dates]}. Provider rows in the range stay, and a range without manual rows changes nothing and writes no entry. The next quote sync stores the provider’s close for a released date; a security without a provider keeps no quote for it. A missing or invalid date answers 422 naming it, to before from 422 on to, an unknown security 404. The operator releases from the security’s Quotes tab (Release…, Sprint 17), through the same write.
GET /api/v1/securities/:security_id/quotes/manual reads the security’s manual quotes over its whole stored history — the read a release stands on (Sprint 17, portfolixir.quotes.manual): count, first and last (the first and last manual date, null without one), stored_count (every stored quote, of any source), stretches — each a run of manual quotes with no quote of another source between them, {"from", "to", "count"}, ascending, the newest limit of them (the list family’s: default 100, capped at 1000, echoed in meta.limit) — stretch_count (all of them), and sync_adapter: whether the quote sync can fetch the security — an adapter for its provider that can ask for it (Yahoo needs a ticker), the checks the sync makes before it fetches anything. Where it is false a released date keeps no quote; where it is true a fetch can still fail. from and/or to (inclusive; an absent bound is open) add range {"from", "to", "count"}: the manual quotes a release of exactly that range would remove. to before from answers 422 on to, an invalid date 422 naming it, an unknown security 404.
POST /api/v1/securities/:security_id/sync_quotes triggers quote sync for one security. The response includes status (ok, skipped, or error); skipped and error responses may include a reason such as missing_ticker or no_provider_adapter, and persist_failed when the fetched quotes could not be stored. A history of any length is stored in one sync, and in the scheduled sync one security that fails is that security’s error while the others are still synced. One sync of a security runs at a time: while one runs, from any path, a second answers 409 Conflict and calls no provider. A newly created security’s quote history is fetched in the background on one queue, one security at a time, whether it came from the API, the page or an import.

Example quote upsert payload:

{
  "quotes": [
    {
      "date": "2026-05-15",
      "close": "123.45"
    }
  ]
}

Example quote upsert response, the first date having replaced a synced row:

{
  "data": {
    "upserted": 2,
    "replaced": ["2026-05-15"]
  }
}

Example quote sync response:

{
  "data": {
    "status": "skipped",
    "reason": "missing_ticker"
  }
}

Portfolios and Accounts

Portfolio writes are deprecated (ADR-0024) — compatibility only; use buckets/views for grouping. Portfolios were demoted to internal compatibility records: the UI groups exclusively through buckets and views, and depots/cash accounts no longer need a portfolio_id (a deterministic internal default is bound automatically). POST /api/v1/portfolios and PATCH /api/v1/portfolios/:portfolio_id keep working but answer with a Deprecation: true response header. Sunset note: after two releases without external portfolio writes, a follow-up story merges the records into buckets and views (the ADR’s exit criterion) — plan migrations to POST /api/v1/buckets and POST /api/v1/views now. Every record written here stays visible in the UI’s read-only “Portfolio records (compatibility)” admin list, so nothing becomes invisible.

GET /api/v1/portfolios lists portfolios (compatibility records).
POST /api/v1/portfolios creates a portfolio with a portfolio object. Deprecated — answers with Deprecation: true; prefer buckets/views.
GET /api/v1/cash_accounts lists cash accounts. Each carries a balance (decimal string, in the account’s own currency) derived on read from the ledger: amounts are stored as positive magnitudes and the transaction type implies the direction (deposits, dividends, interest, tax refunds and sells add cash; removals, fees, taxes and buys remove it; a cash transfer debits its account and credits the counter account). A balance_adjustment snapshot (see below) anchors the balance to a stated absolute amount as of its date, after which only later bookings adjust it.
POST /api/v1/cash_accounts/:id/balance records an absolute balance snapshot for one account (ADR-0009): the current balance as of a date, instead of mirroring every booking. Body {"date": "2026-06-01", "amount": "4250.00"} (notes optional); amount is a decimal string and may be negative (an overdraft). It stores a balance_adjustment transaction and returns it. The balance then anchors to that amount and only bookings dated strictly after the snapshot change it, so moving money between own accounts needs no transfer entry. Unknown accounts return 404 Not Found.
POST /api/v1/cash_accounts creates a cash account with a cash_account object. portfolio_id is optional (ADR-0024): when omitted, the account is bound to the deterministic internal default portfolio; an explicit id keeps winning for compatibility clients. The optional liquidity_role (default free_cash) classifies the account: free_cash is genuine deployable cash; credit_line is an overdraft/Lombard facility whose negative balance is a liability and whose unused headroom is never liquidity (it never enters deployable cash, even with a positive balance — type beats sign); reserve is a visible-but- excluded bucket (e.g. a business account). Only free_cash accounts with a non-negative balance contribute to the valuation’s deployable cash and its cash_quote. An unknown value is rejected with 422 Unprocessable Entity. A name another cash account in the portfolio carries as its name or as one of its former names answers 422 with errors.name, because an import naming it already books to that account (ADR-0050 §4).
Every cash-account and securities-account payload carries former_names (ADR-0050 §4), a list of strings: the names the account was known by. The Portfolio Performance import resolves a file’s account name by the live name first, then by the former names, so a row that names a former name books onto this account. Two accounts of one kind in a portfolio never share a live or former name; names two accounts already shared before this rule resolve to neither, and the import waits for the operator to pick one. A name is stored without leading or trailing spaces, as the import reads it, so a name that differs from another account’s only by them is that name.
GET /api/v1/cash_accounts/:id returns one cash account. An account a merge took away answers 404 with errors.merged_into {"kind": "cash_account", "id": …}, the account its history lives on now, followed through every later merge (ADR-0050 §12).
PATCH /api/v1/cash_accounts/:id updates a cash account (name, currency_code, notes, liquidity_role); portfolio_id cannot be changed. The currency_code freezes once a transaction references the account through either leg or a securities account links to it (ADR-0050 §11): a change then answers 422 with errors.currency_code counting the references, for example ["is frozen once referenced (1 securities account, 12 transactions)"], and nothing is written, so booked history is never re-denominated. A rename keeps the previous name in former_names, and renaming back to a former name consumes it. While another cash account in the portfolio still carries the previous name as its live name, the previous name is not kept: an import naming it books to that other account (merge or rename that account to change this). A new name another cash account carries as its live or former name answers 422 with errors.name.
DELETE /api/v1/cash_accounts/:id/former_names?name= removes one former name, journaled, and answers the account (portfolixir.cash_accounts.remove_former_name). An import that still names ‘' will then create a new account. A name the account does not carry answers `404`, a missing `name` `422`. A name stored before invisible characters were refused may be given in the spelling the MCP companion lists it in, each such character written `[U+XXXX]`; a stored name of those very letters is matched first (E25).
DELETE /api/v1/cash_accounts/:id deletes a cash account that no transaction references through either leg and no securities account links to. Otherwise it returns 409 Conflict with errors.referenced_by (for example {"transactions": 12, "securities_accounts": 1}), errors.remedy merge and errors.remedy_route, the merge preview GET /api/v1/cash_accounts/:id/merge_preview?target_id= completed with the id of the account to keep: a merge moves the history, a delete never discards it. An unreferenced account’s bucket links are removed first, journaled (ADR-0050 §11). A delete that loses a race to a concurrent write, with nothing referencing the row afterwards, answers 409 Conflict with errors.detail alone and deletes nothing: read the row again and retry (#954).
GET /api/v1/cash_accounts/:id/merge_preview?target_id= previews merging the account (the source) into target_id (the target, the account that stays) — a read that writes nothing (ADR-0050 §7, §10; portfolixir.cash_accounts.merge_preview). Both accounts must share the portfolio, the currency, the liquidity role and the bucket set; otherwise it answers 409 Conflict with errors.code (same_account, not_live, portfolio_mismatch, currency_mismatch, liquidity_role_mismatch, buckets_mismatch, legacy_hashed_anchor for a balance anchor that still carries an import hash from before the import-hash kind check and would have to be restated or moved, or unstorable_anchor for an anchor whose restated amount would need more than the amount column’s 6 decimal places — the other account’s balance carries the fraction of a trade booked without its amount; record that amount, then preview again), errors.detail and errors.guards; for the last two errors.anchors names each anchor (id, date, cash_account_id), and for unstorable_anchor errors.bookings names the trades booked without their amount. An unknown source answers 404, a source already merged 409 already_merged with errors.merged_into, a missing target_id 422. The 200 carries:
- plan_digest, the digest the merge takes;
- source and target, each with its balance (the fold of every booking, as GET /api/v1/cash_accounts reports it), transaction_count, bucket_ids and former_names; guards; linked_depots (the source’s, which move to the target);
- internal_transfers: the transfers between the two, which the merge deletes — both legs become one account;
- key_equal_pairs: a source booking whose day, kind and amounts equal a target booking’s, paired one to one, lowest id first, and choice_required when there is one;
- former_names: the names the target gains (appended), those another account already carries (not_kept, with held_by), and the target’s list after;
- outcome_by_collapse_key_equal with "false" (keep both bookings of a pair) and "true" (delete the source’s): the target’s balance and transaction_count after, moved_transaction_ids, deleted (each with its reason: internal_transfer, collapsed_duplicate or folded_anchor), restated_anchors (every balance anchor that stands on the target afterwards, as stated + other_balance = after: the other account’s balance at the end of that day, from its bookings before the merge; on a day both accounts carry anchors the target’s last one holds both and the others are deleted), flow_changes (the external flows a collapse removes — kind removed — and those it moves into a later balance anchor of the account its booking stood on — kind absorbed, the source’s own or, for a collapsed transfer, the third account’s —, each with cash_account_id, the anchor’s or booking’s transaction_id, date, change and collapsed_transaction_id), other_accounts and positions (what a collapsed transfer or trade changes elsewhere);
- balance_basis, the computation basis of the balances and the restated anchors: a balance is the fold of every booking of the account, as GET /api/v1/cash_accounts reports it; a restated anchor is its stated amount plus the other account’s balance at the end of that day, from that account’s bookings before the merge;
- reimport_note, what the merge does to the next Portfolio Performance import: the source’s names lead there (except one another account still carries, former_names.not_kept), and a re-import of an export already applied creates nothing.
Every decimal is a string. The digest covers both accounts, every booking either references with its updated_at, every figure and the guards; the choice is not part of it, so one pair has one digest.
POST /api/v1/cash_accounts/:id/merge with {"target_id": …, "plan_digest": …, "collapse_key_equal": …} merges under the token (portfolixir.cash_accounts.merge). collapse_key_equal is required when the preview lists key_equal_pairs — 422 without it, naming how many — and is never preselected: ask the operator. It answers 201 Created with the merge record (id, kind, source_id, target_id, portfolio_id, source_snapshot, manifest — every booking moved, restated or deleted, the depots re-pointed, the bucket links removed, the names appended, the choice, null where the preview listed no key_equal_pairs —, plan_digest, actor_type, actor_label, inserted_at) and already_applied: false. In one transaction, one audit-journal entry per row: the transfers between the two and, with true, the source’s paired bookings are deleted and their content hashes retired; every balance anchor is restated as the preview said; every other booking of the source and its linked depots move onto the target; the merged balance is checked against the sum of both accounts on every day either has a booking and today (409 identity_check_failed rolls the merge back otherwise — a check for a defect, never an expected answer); the source’s bucket links are removed and the source is deleted; its name and former names become former names of the target, except a name another cash account still carries as its live or former name, which is not kept (former_names.not_kept in the preview) and keeps leading an import to that account. A booking, a figure or a guard that changed since the preview answers 409 with errors.code plan_changed and the fresh preview in errors.preview, and writes nothing. A retry of a completed merge of the same pair answers 200 with the original record and already_applied: true, journaling nothing; a source already merged into another account answers 409 already_merged with errors.merged_into. A missing plan_digest or target_id, or a collapse_key_equal that is not a boolean, answers 422. There is no unmerge: the record and the journal’s before-images reconstruct what a merge did. The operator merges from the row menu on Accounts & depots (Merge into…), which shows this preview and applies it with its digest.
GET /api/v1/securities_accounts lists depots/securities accounts.
POST /api/v1/securities_accounts creates a depot/securities account with a securities_account object. portfolio_id is optional (ADR-0024): when omitted, the depot is bound to the deterministic internal default portfolio. A name another depot in the portfolio carries as its name or as one of its former names answers 422 with errors.name (ADR-0050 §4).
GET /api/v1/securities_accounts/:id returns one securities account. A depot a merge took away answers 404 with errors.merged_into {"kind": "securities_account", "id": …}, followed through every later merge (ADR-0050 §12).
PATCH /api/v1/securities_accounts/:id updates a securities account (name, notes, cash_account_id); portfolio_id cannot be changed. A rename keeps the previous name in former_names under the same rules as a cash account’s: renaming back consumes it, a previous name another depot still carries as its live name is not kept, and a name another depot carries as its live or former name answers 422 with errors.name.
DELETE /api/v1/securities_accounts/:id/former_names?name= removes one former name of a depot, journaled, and answers the depot (portfolixir.securities_accounts.remove_former_name). An import that still names ‘' will then create a new depot. The name is matched as for a cash account, the `[U+XXXX]` spelling included.
DELETE /api/v1/securities_accounts/:id deletes a securities account that no transaction references through either leg. Otherwise it returns 409 Conflict with errors.referenced_by, errors.remedy merge and errors.remedy_route, the merge preview GET /api/v1/securities_accounts/:id/merge_preview?target_id=. An unreferenced depot’s default buckets and position overrides are removed first, journaled: one entry for the default set, one per position. A delete that loses a race to a concurrent write, with nothing referencing the row afterwards, answers 409 Conflict with errors.detail alone and deletes nothing: read the row again and retry (#954).
GET /api/v1/securities_accounts/:id/merge_preview?target_id= previews merging the depot (the source) into target_id (the target, the depot that stays) — a read that writes nothing (ADR-0050 §7, §10; portfolixir.securities_accounts.merge_preview). Both depots must share the portfolio and the default bucket set, and every position must keep its view membership: for each security the source holds, where the target holds it too the two effective bucket sets must be equal; where the target does not, the source’s set is carried over. Otherwise it answers 409 Conflict with errors.code (same_account, not_live, portfolio_mismatch, buckets_mismatch, or position_buckets_mismatch, whose errors.detail names each position and both bucket sets — or an override to carry that holds more than one scope bucket, which the target’s position cannot take), errors.detail and errors.guards. An unknown source answers 404, a source already merged 409 already_merged with errors.merged_into, a missing target_id 422. The 200 carries:
- plan_digest, the digest the merge takes;
- source and target, each with its cash_account_id, bucket_ids (the default set), former_names and transaction_count; guards;
- internal_transfers: the security transfers between the two, which the merge deletes — both legs become one depot;
- key_equal_pairs: a source booking whose day, kind, security, cash account and amounts equal a target booking’s, paired one to one, lowest id first, each naming both depot legs (securities_account_id, counter_securities_account_id), and choice_required when there is one;
- position_buckets: per security the source holds or carries an override for, both effective bucket sets, both overrides (null for a position that inherits its depot’s default set, [] for a deliberately empty one) and the action: carry (the source’s override moves to the target), drop_redundant (the target already shows the position in the same buckets), drop_unheld (the source holds no booking of it), clear_target (the target’s override for a security it does not hold is cleared, so the moved bookings keep the default set) or none;
- former_names: appended, not_kept and the target’s list after;
- outcome_by_collapse_key_equal with "false" and "true": the target’s transaction_count after, moved_transaction_ids, deleted (each with its reason: internal_transfer or collapsed_duplicate), positions (every security the source holds, each with source, target and after, each quantity, cost_basis, avg_cost and realized_result; target is null where the target holds no booking of it), rounding_differences, cash_accounts (each cash account a collapsed booking changes, with balance_before and balance_after) and flow_changes (each flow a collapsed booking moves into a later balance anchor of its cash account, kind absorbed, with cash_account_id, the anchor’s transaction_id, date, change and collapsed_transaction_id, as in a cash merge’s preview) and other_depots (each third depot a collapsed transfer names, per security, with securities_account_name, security_name, quantity_before and quantity_after: removing a transfer from it changes its holding too);
- positions_basis, the computation basis of those figures: the quantity is the position fold with each split scaling the position once, rounded at volume scale 6 (ADR-0028 §3); cost_basis and avg_cost are the moving-average cost GET /api/v1/portfolios/:id/holdings states, in the security’s currency, fees and taxes not included — after the merge both depots’ lots combine, so the cost is restated, and a sale the target made between two buys now consumes the combined average; realized_result is, over the position’s sales, each sale’s quantity times its price in the security’s currency less the cost it removed at the running average, and null where that price or cost is not derivable; rounding_differences lists, per position and split date, each split of an affected security where the combined position rounded once differs, at the end of the split’s day, from the two positions rounded apart, with both quantities and their difference — expected and never a refusal, and held to no bound per split: where splits compound, a difference one split leaves is scaled by the next (ADR-0050, amendment of 2026-10-08);
- reimport_note, what the merge does to the next Portfolio Performance import, as for a cash merge.
Every quantity and decimal is a string. The digest covers both depots, every booking either names and the portfolio’s splits of their securities with their updated_at, every figure (the bucket plan among them) and the guards; the choice is not part of it, so one pair has one digest.
POST /api/v1/securities_accounts/:id/merge with {"target_id": …, "plan_digest": …, "collapse_key_equal": …} merges under the token (portfolixir.securities_accounts.merge). collapse_key_equal is required when the preview lists key_equal_pairs — 422 without it, naming how many — and is never preselected: ask the operator. It answers 201 Created with the merge record (as for a cash account; its manifest lists every booking moved or deleted, the overrides carried, dropped and cleared, the default buckets removed, the names appended, the rounding differences and the choice, null where the preview listed no key_equal_pairs) and already_applied: false. In one transaction, one audit-journal entry per row: the transfers between the two and, with true, the source’s paired bookings are deleted and their content hashes retired; every other booking of the source moves onto the target on whichever depot leg names the source, keeping its cash account — the target keeps its own linked cash account, the source’s stays as an account of its own; the target’s quantity of every security is checked against both depots’ bookings on every day either has a booking, every split date and today (409 identity_check_failed rolls the merge back otherwise — a check for a defect, never an expected answer); the bucket plan is written, one journal entry per position; the source’s default buckets are removed and the source is deleted; its name and former names become former names of the target, except a name another depot still carries (former_names.not_kept). A changed plan answers 409 plan_changed with the fresh preview in errors.preview; a retry of a completed merge of the same pair answers 200 with the original record and already_applied: true; a source merged into another depot 409 already_merged; a missing plan_digest or target_id, or a collapse_key_equal that is not a boolean, 422. There is no unmerge. The operator merges from the depot row’s menu on Accounts & depots (Merge into…), through the same preview.
GET /api/v1/merges lists the merge records, newest first (inserted_at, then id) — the audit read of a destructive write (ADR-0050 §12; portfolixir.merges.list). Each record carries id, kind (cash_account, securities_account or security), source {id, name} (the name the merge recorded, since the source no longer exists), target {id, name, merged_into} (merged_into is null while the target lives, otherwise the id a later merge moved it into, followed to the live end), portfolio_id (null for a security), actor_type, actor_label (for an API token, the name of the token entry that applied the merge, as the journal’s), inserted_at and manifest_summary: the record’s manifest with every list replaced by its count — bookings moved, restated and deleted, names appended, quotes moved and dropped —, beside transactions.deleted (still every booking the merge removed) transactions.deleted_by_reason, the same rows counted per reason (internal_transfer, collapsed_duplicate, folded_anchor, collapsed_split; only the reasons present, {} when none), and the operator’s choices as given — collapse_key_equal only where the merge had key-equal pairs, a security merge’s identity_choice and isin_changed_on only where it made that choice (a record written by an earlier version may hold them as sent). meta carries order, count and limit. limit is the list family’s: default 100, capped at 1000, and zero, a negative or a non-number answers 422. The operator reads the same records, with the same counts, in Merges at the end of Accounts & depots (Sprint 17; the survivor’s “merged from” date links its entry).

Example account payloads:

{
  "portfolio": {
    "name": "Household Portfolio",
    "base_currency_code": "EUR"
  }

  "cash_account": {

Transactions and Holdings

GET /api/v1/transactions lists transactions. Optional filters: from/to (ISO dates, inclusive), portfolio_id, security_id, securities_account_id. Invalid filters return 422 Unprocessable Entity with the offending field. An optional fields= (FR-37, comma-separated) selects a sparse fieldset: each row then carries exactly the requested fields. The names are validated against the serializer’s own field list — an unknown name is a 422, never a silent fallback. The human view of fields= (issue #732) is the column picker on the transaction history and on the holdings panel: the same projections, chosen column by column on the page — and the securities list, whose picker predates FR-37, gained the reverse half as its own fields= (see Securities). An optional running_balance_for=<cash_account_id> adds a running_balance to each row — the balance of that cash account after the booking, as a Decimal string in the account’s own currency — plus a top-level running_balance_basis naming the account, its currency and the fold. Two properties the number depends on: the fold always covers that account’s whole history, so a narrowed read (a from, a filter) still reports true balances rather than a partial sum; and a row that does not move the account carries null rather than repeating the previous figure, which would read as “nothing happened here”. An unknown or non-numeric account id is a 422 naming running_balance_for. This is the API and MCP counterpart of the balance column on the Transactions page. limit keeps the newest rows (default 10000, max 50000; zero, negative or non-numeric is a 422).
POST /api/v1/transactions creates a transaction of any bookable kind with a transaction object (per-kind required fields are validated server-side). The bookable type values are buy, sell, dividend, interest, deposit, removal, fee, tax, tax_refund, cash_transfer, inbound_delivery, outbound_delivery and security_transfer (balance_adjustment is written through the dedicated balance-snapshot endpoint, split through the split routes below). Booking semantics worth knowing before the first write: a dividend’s gross_amount is the NET cash credited to the account — withheld taxes ride in taxes, and the income report reconstructs gross as net plus withheld tax. An inbound delivery recorded without a price enters the cost basis at zero — supply the acquisition price when it is known; an outbound delivery removes cost at the position’s running average, so its price is informational only. When reconciling a difference, prefer booking the missing transaction of the correct kind — balance snapshots and unpriced inbound deliveries are last resorts that make numbers look right while distorting cost basis. Amounts are positive magnitudes — the kind implies the direction; only balance_adjustment may carry a negative (absolute) amount. A tax refund — for example the tax credited back when a sale realises a loss — is therefore never a negative taxes value on the sell: book the sell with the taxes actually withheld (or 0), plus a separate tax_refund transaction whose positive gross_amount is the cash credited to the account (cash_account_id and gross_amount are its required fields; the changeset rejects a negative taxes with exactly this guidance). A security settled through a different-currency cash account (for example a USD security bought through a EUR account) is booked in the security’s own currency and carries the cross-currency settlement fields security_amount (trade amount in the security currency), settlement_amount (the trade amount in the account currency, before fees and taxes, which are recorded in the account currency as well) and settlement_fx_rate (account-currency units per one unit of the security currency). When the rate is omitted but both amounts are supplied it is derived as settlement_amount / security_amount (the broker’s actual rate); a currency mismatch with no rate and no amounts to derive one is rejected. Cost basis stays in the security currency so per-position P&L is FX-honest. All three are Decimal strings and null for same-currency bookings. The cash and the settlement must agree (#395): a cross-currency buy’s gross_amount (the cash paid, fees and taxes included) must equal settlement_amount + fees + taxes, a sell’s (the cash received) settlement_amount - fees - taxes, within 0.01 compared at full precision; otherwise the write answers 422 with a gross_amount error naming the implied amount. Without a gross_amount the ledger books quantity × price (plus fees and taxes on a buy, less them on a sale) as the cash, so that is what is compared: a trade priced in the security’s currency and sent without its cash amount answers 422 on gross_amount naming both the amount it would book and the one the settlement implies — send the cash the broker settled. The check runs on create and on a PATCH that changes gross_amount, settlement_amount, fees, taxes or type, or, on a booking without a gross_amount, its quantity or price — a PATCH of the notes or the date of an older booking is never refused by it.
GET /api/v1/transactions/:id returns one transaction.
PATCH /api/v1/transactions/:id updates a transaction (e.g. to fix a mis-imported booking); the per-kind validation still applies. An imported row keeps its content hash, and a balance anchor or a split never carries one (ADR-0050 §1), so changing an imported row’s type to balance_adjustment or split answers 422 on errors.type. A stored split row changes only its notes (E25 S6): a change of its date, security_id, portfolio_id, type or ratio answers 422 naming the field, because a split is booked through POST /api/v1/splits, whose checks a generic update would pass by. A wrong split is deleted whole (DELETE /api/v1/splits/:transaction_id, below) and booked again.
DELETE /api/v1/transactions/:id deletes a transaction. Because trades and holdings are derived, correcting or removing the transaction fixes them too. An imported booking’s content hash goes with it, so a re-import of the same file books it again (only a merge retires a hash, ADR-0050 §3). On a split row it removes that row alone; the split’s other rows keep the event.
POST /api/v1/splits/preview previews a stock split booking (ADR-0028) without writing anything. The request carries security_id, the effective date (ISO, not in the future) and the ratio as a pair of positive integers ratio_numerator/ratio_denominator (10:1 forward, 1:10 reverse; normalized to lowest terms, so 10:5 previews and books as 2:1). The response shows, per portfolio holding the security, the quantity immediately before and after the effective date and the resulting current position (all Decimal strings; the ratio parts stay integers), plus warnings: effective_date_before_history means the effective date predates the security’s earliest recorded transaction — the stored quantities may already be post-split (Portfolio Performance’s split wizard rewrites history destructively), so booking would double-adjust. Check the preview before booking. The preview also renders the stored closes around the effective date (quotes_around) and a quote_basis_check (misclassification guard, ADR-0028 §2): a visible jump indicates a raw series, continuity an already-adjusted one; when that contradicts the per-row source classification the preview warns with quote_basis_contradiction (for synced series that never back-adjust, set the security’s treat_quotes_as_raw flag instead of booking blindly), and with too few closes on either side it reports insufficient_quotes_to_verify_basis instead of implying a clean check.
POST /api/v1/splits books the split: one call fans the event out across all portfolios holding a position in the security at the effective date — one journaled split row per portfolio, inserted atomically — and returns the created transactions (201, regular transaction shape). A portfolio with zero position at the effective date gets no row. A second same-day split for the same security is rejected with 422 on date, naming the existing event, its transaction and its portfolio by their ids (a retried timeout cannot compound the multiplicative event); a future-dated effective date and a security nobody held at the effective date are rejected with 422 too. The security’s splits, each counted by its own magnitude (2:1 and 1:2 both count 2), may multiply to at most 10^12 with the new one included; a ratio past that answers 422 on ratio from preview and booking alike, and nothing is written (E25 S4). The generic POST /api/v1/transactions endpoint rejects the split kind — these two routes are the only way a split is booked.
DELETE /api/v1/splits/:transaction_id deletes a split the way it was booked, as one fact (Sprint 18 U1, #912): from any of its rows, every split row sharing that row’s security, date and normalized ratio — one per portfolio — in one transaction, each row journaled with its before-image. It answers 200 with data.transactions, the removed rows in the regular transaction shape, ordered by portfolio. Afterwards no portfolio carries the event: holdings count without it, the quote reads no longer adjust for it, and POST /api/v1/splits books the corrected ratio on the same day. An unknown or already deleted row answers 404; a booking of another kind answers 422 on transaction_id naming DELETE /api/v1/transactions/:id; a failure on any row deletes nothing. The security’s other splits stay.
GET /api/v1/portfolios/:portfolio_id/holdings lists derived holdings for a portfolio, one row per (depot, security). Each row carries quantity, a moving-average avg_cost and cost_basis (price-based, so fees and taxes are not folded into the unit cost), the latest_price, market_value, and unrealized_pnl_abs/unrealized_pnl_pct against that price, plus security_name and currency_code. Those figures are in the security’s own currency — enforced by the cost pair the ledger fold carries (ADR-0033), no longer an assumption; a holding whose security has no quote returns null price, market value and P&L. Each row additionally carries the ADR-0033 base-currency P&L decomposition: base_cost (the settlement-leg amount actually paid, with its base_currency), price_return_abs/price_return_pct (the security’s own price move, converted at today’s rate), currency_return_abs/currency_return_pct (the FX effect on the amount originally invested) and total_return_base_abs/total_return_base_pct — with total = price + currency holding Decimal-exactly. A row whose decomposition is not derivable reports decomposed: false with an undecomposed_reason ("missing_native_cost" — no security-currency leg in the recorded booking, in which case cost_basis/avg_cost/P&L are null too; "missing_base_cost" — the settlement leg is not in the base currency; "missing_fx" — no stored current rate; "no_price"), never a guessed number. The response is self-describing (FR-13): it carries currency_basis: "security_currency" plus a currency_basis_note naming which field is in which currency, and an as_of date. Since issue #1142 a holding whose cost_basis is "0" (shares delivered in at no cost, such as a spin-off, or bought at a price of 0) keeps its unrealized_pnl_abs and reads unrealized_pnl_pct null, never "0": a return on no cost is undefined, and 0 would read as flat. The envelope’s computation_basis.unrealized_pnl_pct states the rule. In the same way a holding whose base_cost is "0" reads price_return_pct, currency_return_pct and total_return_base_pct null beside its three amounts, and computation_basis.decomposition_pct states the rule. Holdings are derived on read with no stored snapshot, so as_of is the read date. Unknown portfolios return 404 Not Found. Optional filters: security_id, securities_account_id. An optional fields= (FR-37, comma-separated) selects a sparse fieldset per row, validated against the serializer’s own field list; an unknown name is a 422.
GET /api/v1/realized_gains (issue #724) returns the Cash-flow Realized-gains roll-up: FIFO-matched realized P&L across all securities and portfolios, grouped by each sale’s close date into an annual year → month matrix in the base currency. The FX basis is D-1 (signed 2026-08-20): each sale converts through the EUR hub at the rate stored on its own close date; a sale with no stored rate for that day is excluded from every converted total and named in excluded (count + securities) — never converted at a neighbouring date’s rate, never silently dropped. The payload carries computation_basis (series, window, reference, gaps) and a conversion_note; the human view is /cashflow?tab=realized. limit bounds the annual matrix to its newest years (default 100, max 1000); computation_basis.window names the cut when years were dropped, and the answer echoes the applied limit.

Since issue #807 the payload also carries trades — the closed round-trips themselves, newest close first, each with security_id, security_name, open_date, close_date, holding_period_days, quantity, basis, proceeds, realized_pnl_abs and realized_pnl_pct in the trade’s own currency and realized_base in the base currency — and summary: realized_total, hit_rate (the share of closed trades whose result is strictly positive; a break-even trade counts as a miss) and average_holding_period_days. The three figures are derived from the same converted set as the matrix and the list, so an excluded sale is in none of the three; with no closed trades hit_rate and average_holding_period_days are null rather than 0, because the average of nothing is not zero. limit cuts only the matrix’s years — the figures and the list always read the full history, and computation_basis.summary states all of this in the payload.

Since issue #984 every trade also carries annualized_return: the round-trip’s money-weighted return per year, as a fraction ("0.304701" is 30.47 % a year). It is the XIRR solver of ADR-0034 §2 (Act/365) over the trade’s own flows — each consumed lot’s buy on its open date for its prorated cost (quantity × buy price plus its buy fees and taxes prorated by the quantity taken), and the sell’s proceeds on the close date — in the trade’s own currency, so it annualizes realized_pnl_pct, not realized_base; rounded to 6 places, and a loss stays above −1. It is null with annualized_return_reason no_cost_basis when the trade’s basis is "0" (since issue #1142; this reason comes first, because with no cost there is nothing to annualize however long the trade was held), null with holding_period_under_365_days when the trade’s holding_period_days is below 365 (ADR-0034 §2 does not annualize a window under a year: 5 % in 14 days would read as about 257 % a year), and null with the solver’s reason (no_sign_change, a total loss among them; no_root; amount_out_of_range) when no rate solves the flows. Dividends and interest received while the trade was open are not included. computation_basis.annualized_return states the rule.

Since issue #1142 a trade whose basis is "0" — a buy booked at a price of 0 with no fees or taxes, a bonus or free share — reads realized_pnl_pct null, never "0": its realized_pnl_abs and realized_base still state the result, but a return on no cost is undefined, and 0 would read as a flat trade. computation_basis.realized_pnl_pct states the rule.

Since issue #984 the payload also names the sells the FIFO matcher could not pair with a buy, in unmatched_sells: a count and, newest first, each sell’s security_id, security_name, date and the quantity no lot covered. Shares that arrived by an inbound delivery open no lot, so their sale is no closed trade, and a sell larger than the shares bought closes what it can and leaves the rest here. Neither is in the figures, the list or the matrix; computation_basis.unmatched_sells says so. The security’s own trades read below lists the same sells as orphan_sells.

Since issue #1108 (the ADR-0015 amendment of 2026-10-07) a trade’s fees and taxes are read in its cash account’s currency, the currency of the cash leg they are part of: a cross-currency trade booked in the security’s currency converts them into it at its own stored settlement_fx_rate (fee ÷ rate, account units per one security unit), never at a hub rate, before they enter basis and proceeds. So basis, proceeds, realized_pnl_abs and realized_pnl_pct are in the trade’s currency_code, and realized_base is the cash the round trip moved when the broker’s rate and the hub’s agree: 10 bought at 100 USD for 800.00 EUR with 6.00 EUR in fees and taxes and sold at 120 USD for 960.00 EUR with 3.00 EUR in fees read basis "1007.5", proceeds "1196.25", realized_pnl_abs "188.75" and realized_base "151". A trade booked in its account’s currency (a Portfolio Performance import’s form), in a third currency or without a stored rate adds them as recorded. A closed trade that closes a lot booked in another currency than its sell adds the amounts as booked, unconverted, in two currencies under one currency_code: issue #1198, an open decision. computation_basis.fees_and_taxes states the rule and names that case.
GET /api/v1/external_flows (issue #725) returns the Deposits & withdrawals roll-up: the booked external cash flows (deposit and removal) across all portfolios, per year and month with deposits, withdrawals and a net. Deliberately narrower than the performance walk’s invested_capital, which additionally counts securities delivered in/out at market value and balance-snapshot residuals — the difference is stated in computation_basis.excludes. FX basis as in the sibling facet: EUR hub at the rate stored on each flow’s own booking date, unconvertible flows excluded and named by their cash account. Each flow is read in its cash account’s currency, never the booking’s: a deposit booked in another currency with a stored settlement rate (ADR-0015) is the cash the account was credited, and computation_basis.currency states the rule (issue #1107). The human view is /cashflow?tab=flows. limit bounds the annual matrix to its newest years (default 100, max 1000); computation_basis.window names the cut when years were dropped, and the answer echoes the applied limit.
GET /api/v1/costs (issue #726) returns the Costs roll-up: fees and taxes across all portfolios at overview level only, per year and month with yearly fee, tax and combined totals. The series sums the fee and tax legs riding any transaction plus the standalone fee/tax bookings, with tax_refund netted against taxes; gross amounts are never summed — a buy’s gross includes its legs while a sell’s is net of them, so a gross sum would describe something else. The legs-not-gross rule is stated in computation_basis.series. FX basis as in the sibling facets: EUR hub at the rate stored on each booking’s own date, unconvertible costs excluded and named by their currency. Since issue #1107 each cost is read in its cash account’s currency, the currency of the cash leg it is part of, as the performance walk reads trade costs: a cross-currency trade’s fees and taxes are converted from the account’s currency, never from the security’s, and an unconvertible one is named by the cash account’s currency; a booking without a cash account is read in its own. computation_basis.currency states the rule. The human view is /cashflow?tab=costs. limit bounds the annual matrix to its newest years (default 100, max 1000); computation_basis.window names the cut when years were dropped, and the answer echoes the applied limit.
GET /api/v1/holdings/by_security returns the global per-security valuation across all portfolios: one holdings row per currently held security with its security_id (an integer), total quantity, and current market_value converted to the EUR hub, plus a valued flag. valued is false (and market_value is null) when the security has neither a quote nor a trade price, or no exchange-rate path to EUR, so a missing quote or rate never silently distorts a value. Each row also carries the resolved native latest_price with price_currency and price_source, and an unvalued_reason that says why a row is unvalued: "no_price" (nothing resolves at all) or "missing_fx" (the price is known but no stored rate path reaches EUR); null when valued. Rows are sorted by security_id. The response is self-describing: a top-level currency of "EUR", an as_of read date (the report is derived on read, so as_of is today’s date, not a stored snapshot), and a note describing the hub conversion. This is the cross-portfolio, base-currency counterpart to the per-portfolio holdings list (which stays in each security’s own currency with no FX); for one portfolio’s totals and weights use the valuation endpoint instead.
GET /api/v1/holdings/negative returns the negative-holdings data-quality report: every (depot, security) position whose derived quantity is below zero — import debris from unmodeled corporate actions — as rows (with depot_name, security_name, isin, portfolio_id and the negative quantity as a Decimal string) plus totals with each listed security’s total quantity across all depots, so transfer debris (negative in one depot, positive in another) is distinguishable from a truly negative total. Self-describing with an as_of read date and a note. Nothing is repaired automatically; fix the security’s transaction history.
POST /api/v1/holdings/reconcile compares a user-supplied external position list (a broker statement or depot overview, parsed client-side into rows) against the ledger-derived holdings — strictly read-only: the list arrives only in the request body, is never persisted or logged, and no data is fetched from anywhere (ADR-0029 §6, FR-35). Each row is {identifier, quantity} with optional currency and an optional pinning security_id; quantity must be a canonical dot-decimal string (anything else — comma decimals, thousands separators, exponents — is a 422 naming the row; locale parsing is the client’s job), and an empty rows list is a 422. Identifiers match through the same stable-identity ladder the import uses: an ISIN-shaped string (format and check digit) matches via the ISIN tier only (current ISINs first, then recorded former ISINs — matched_via: "former_isin"); any other string is tried against WKN, ticker+currency and name+currency with the exactly-one rule applied across the union of those tiers — a string matching one security’s WKN and another’s ticker lands under ambiguous with the candidate securities, never a silent pick, and a currency-less row cannot match by ticker or name (unmatched with reason currency_required). The response is self-describing (basis with as_of, scope, and a delta note) and reports: matched rows (one per security — rows resolving to the same security are aggregated with their external quantities summed and the contributing rows listed), ordered by the lowest input row index each match aggregates so a finding maps back to the submitted line, each embedding the security’s identity only (id, name, ticker_symbol, isin, wkn, currency_code), with the matched_via tier (isin, former_isin, wkn, ticker, name, or pinned), ledger_quantity, external_quantity and delta (external - ledger) as exact Decimal strings — ticker/name matches carry weak_match: true and the caveat “confirm the security before booking” —, ambiguous and unmatched rows, and missing_from_list (held ledger positions the external list does not cover). The embedded guidance is part of the contract: resolve a difference by booking the missing transaction of the correct kind; balance snapshots and unpriced deliveries are last resorts that distort cost basis. Optional scope: portfolio_id or view (a view id; mutually exclusive — both at once is a 422), default the whole instance; an unknown portfolio or view is a 404.
GET /api/v1/portfolios/:portfolio_id/valuation returns a live valuation of a portfolio: each held position priced from its latest quote close, a total_value, and each valued position’s weight (its share of the total). Each position’s market value is converted into the portfolio base_currency (top-level field) from stored exchange rates; per-position security_currency shows the native currency. A security without any quote is priced at the latest own trade price (price_source: "trade", counted in the top-level trade_priced_count); a quoted position carries price_source: "quote". Every position carries price_date, the date its price is from, and the top-level stale_priced_count counts the quoted positions whose quote is older than the data-quality staleness threshold (the same ?dq=stale_quote day count) — the remedy is the security’s is_retired flag, which the performance walk keys on, or a quote sync; a retired holding is therefore not counted, its stale close is expected. The top-level newest_quote_date is the newest stored quote date across the quoted, non-retired positions (null when none is quote-priced) — the freshness fact the Overview’s key-figure strip shows; the view valuation carries both fields as well. A position with neither price or no exchange-rate path to the base currency is returned with valued: false, price_source: null and null market value and weight, so a missing price or rate never distorts the total. Unknown portfolios return 404 Not Found. Weights are raw shares (market_value / total_value) emitted at full Decimal precision; because they are normalized ratios they need not sum to exactly 1 (round for display). Market values and total_value are exact. The valuation also carries cash: cash_balances lists each cash account (balance in its own currency, plus base_value/valued after converting to the base currency, its liquidity_role, and a deployable flag), total_cash is the base-currency sum of the valued cash accounts (so a drawn credit line’s negative balance still reduces it), and total_with_cash is total_value + total_cash. cash_quote is the deployable-cash share of the portfolio: deployable cash is the sum of free_cash accounts with a non-negative balance (deployable: true), and the quote is computed as if the other accounts did not exist (counting_cash / (total_value + counting_cash), 0 when there is nothing to value yet) — so a reserve account or a credit line stays listed and inside total_cash without ever reporting fake liquidity. The response also emits counting_cash (Decimal string) — the deployable cash that enters the quote — so a consumer can reconstruct cash_quote itself. An account whose currency has no rate path to the base is reported valued: false and excluded from total_cash, mirroring how unpriceable positions are handled. unvalued_cash_count (#1081) counts such accounts that hold a non-zero balance — the money total_cash and total_with_cash leave out; an empty one is listed with valued: false and not counted — in every form of the read, with or without include_positions, so the roll-up-only read states the gap too; the valuation_note states the rule. The response is self-describing (FR-13): it carries an as_of date (the read date — the valuation is computed live with no stored snapshot) and a valuation_note stating that totals are in base_currency via the EUR hub and that the per-position price_source and valued fields indicate price staleness. An optional include_positions=false (FR-37) returns the roll-up only — totals, cash balances and cash quote without the per-position rows; the response states which shape was returned via positions_included.
GET /api/v1/portfolios/:portfolio_id/performance returns the portfolio’s true time-weighted rate of return (TTWROR), computed the Portfolio Performance way: the portfolio is valued daily (quotes on or before each day, converted at that day’s rates, plus cash), external flows — deposits, removals, deliveries, and balance-snapshot jumps — are neutralised, and daily returns chain geometrically (see ADR-0010). Optional query params: period (ytd, 1y, 3y, 5y, max — default max; an unknown period returns 422 Unprocessable Entity), year=YYYY for one calendar year, from=/to= (ISO dates, both required, from <= to) for a custom range — both clamped honestly to the available history, with a backwards or malformed range returning 422 — and series=true to include the daily points (date, value, flow, cumulative_ttwror). The response carries ttwror, start_date/end_date, start_value/end_value, net_external_flows as Decimal strings, and suspect_dates — dates of bookings older than 1970 (import typos) whose effects were applied on the first plausible day. Alongside ttwror the response also carries the money-weighted return irr — the single annualised rate that discounts the period’s dated external flows and terminal value back to zero (NPV(r) = Σ cf/(1+r)^(days/365) = 0), the figure Portfolio Performance shows next to TTWROR. It is a Decimal string, or null when no rate exists (fewer than two flows, all flows the same sign, or the solver does not converge) or when an amount lies outside the range the solver’s one float step carries, which only implausible stored data reaches; the read never fails on such an amount, and computation_basis.gaps names these cases (E25 S4). Securities without quotes are priced at the latest own trade price (see the valuation endpoint). Unknown portfolios return 404 Not Found. Since the daily walk may be served from a durable derived value (ADR-0039), the response is never silent about freshness: as_of (ISO-8601 datetime) is the instant the walk was computed — possibly older than the request when the underlying data has not changed since — and stale (boolean) marks a superseded value served while a fresh one computes; a stored value is invalidated by every write that can affect it, so stale: false means current against the ledger. The response also states the metric’s computation basis (computation_basis): the input series, the effective window, the reference series (null — TTWROR/IRR have none) and the treatment of gaps. A cash account in a foreign currency counts zero on every day it holds money while its currency has no rate path to the base currency, and the day the first rate arrives its whole balance enters the end value without being a flow: unvalued_cash_accounts names each such account of the scope that counted zero on a window day or on the day before the window, whose close is the start value (#1055, ADR-0051 §10) — cash_account_id, name, currency_code, balance (its native balance on its last such day, a Decimal string in that currency, never converted), unvalued_days (its days, the day before the window (the start value) included), unvalued_reason (no_rate), unvalued_through_end (true when it still counted zero on the window’s last day) and first_rate_date (the ISO date the currency’s first rate path arrived when that falls inside the window and the account held money at zero on the day before, else null) — sorted by name, [] when every balance was valued; computation_basis.gaps names the field.
GET /api/v1/portfolios/:portfolio_id/performance/benchmark returns the benchmark comparison (ADR-0046, FR-9): the portfolio’s own external flows replayed into a benchmark, the read that answers “was the effort worth it”. benchmark= is required — rate:<decimal> for a fixed effective annual rate compounding daily from a base of 1 (Act/365; rate:0.02 is 2 % p.a., the savings-account baseline and, in v1, how inflation is expressed; accepted between -0.999999 and 10, the IRR solver’s own domain) or security:<id> for a catalog security flagged is_benchmark (list them with GET /api/v1/securities?is_benchmark=true; any other security answers 422, {"errors": {"benchmark": ["is not a benchmark security"]}}). A security a merge took away is refused the same way; when the survivor at the live end of its merge chain is itself a flagged benchmark, the body adds merged_into {"kind": "security", "id": …} naming it, as the merged-away reads do, and a retry with that id compares (#959). A survivor that is not flagged, a chain that ends at a row deleted since, and an id no merge names answer without it. The view and the view-less comparison below answer the same. period, year, from/to, view= and series=true behave like the performance read. The response carries benchmark (kind, then annual_rate or security_id/name/ currency_code), requested_window and window — the days the comparison actually covers, window.rebase_day naming the close the benchmark is rebased to (the close before the window, or the window’s first day when it opens with no value): a flow dated before the benchmark’s first priced day (a close and a rate path to the base currency; a stored close of 0 is not a price) is not replayed on its own day — it enters through the window’s opening value and is listed in excluded_flows (date, flow) — and both sides are chained over the covered window — then the two comparisons Portfolio Performance shows. bought_once is flow-neutral: benchmark_return, the benchmark rebased at rebase_day, next to portfolio_ttwror over the same window; with series=true it also carries the daily cumulative_return points for a chart overlay. savings_plan is flow-matched: invested_capital, portfolio_end_value and benchmark_end_value — the window’s opening value and every external flow invested into the benchmark at that day’s price (a fixed rate: at par) — end_value_delta (real minus synthetic, the figure that answers the question), portfolio_irr and benchmark_irr (ADR-0034’s XIRR on identical dated flows), portfolio_mwr and benchmark_mwr (the non-annualized period rates a window shorter than a year reads instead) and benchmark_units. All financial values are Decimal strings; as_of/stale carry the walk’s freshness (ADR-0039) and computation_basis states the input series, the window, the reference, the treatment of gaps and the assumptions — the synthetic portfolio is frictionless (frictionless: true: no fees, no taxes), which biases the comparison against the real portfolio. The basis names a benchmark security as security <id> (<currency>), never by its stored name, which travels only as data in benchmark.name (E25). A missing or malformed benchmark is 422; a portfolio with nothing to walk, or a benchmark without a quote in the window, answers null figures with window.start_date: null and every flow named in excluded_flows. A cash account whose balance counted zero before its currency’s first rate — the jump that rate brings sits in portfolio_ttwror and end_value_delta — is named in unvalued_cash_accounts, the performance read’s entries for the covered window ([] without one; #1055). Nothing is persisted: the comparison is derived on read and memoised like the walk it depends on.
GET /api/v1/portfolios/:portfolio_id/performance/contribution returns the contribution analysis (FR-41, ADR-0051): which position made how much of the period’s money result, the “+x EUR in the period” figure beside the TTWROR. period, year, from/to and view= behave like the performance read, and so do its errors (a malformed view or period 422, an unknown portfolio or view 404). Each row of positions carries security_id, name, isin, start_value, end_value, net_flows, income, costs and contribution — `end_value − start_value − net_flows
- income − costs, in the base currency with the currency move included — plusheld_at_start, held_at_end, unvalued_days and unvalued_reason(no_price, no_rate or null). costsare the fees and taxes of the position's own trades, converted from each trade's cash account currency, the currency they are recorded in (#1051); a trade with no rate for its price currency flows in at its cash leg less those costs. A position bought and sold inside the window is listed although it is held at neither end. A day on which a held position has no price or no rate path counts zero, as in the walk, and the position stays in the sum, named with its days. A foreign-currency cash balance held before its currency's first rate counts zero the same way, and the first rate brings its whole value intocash_currency_effect:unvalued_cash_accountsnames the account, exactly as the performance read of the same scope and window does, with its nativebalance, itsunvalued_days(the day before the window included),unvalued_through_end and the first_rate_date(#1055). The rows are sorted by contribution, largest first, with no share, rank or label.remainderholds what no position does, each line summed from its own bookings and never a plug:interest(every interest booking, bond coupons included),standalone_fees_and_taxes(fee, tax and tax-refund bookings no trade carries) andcash_currency_effect(the revaluation of foreign-currency cash, a trade's settlement difference between its cash leg and price × quantity plus costs, and what a cash transfer between currencies leaves).totals carries result (end_value − start_value − net_external_flowsof the performance read over the same window),positions and remainder, and positions + remainder = result, exact in Decimal while the conversion quotients terminate and to 34 significant digits otherwise. The response carriesportfolio_id,view_id (null unscoped; a view also echoes view: {id, name}),period, base_currency, start_date/end_date, as_of/staleandcomputation_basis with assumptions; all financial values are Decimal strings. A window holding no walked day — a future year, a range before the history — answersstart_date: null, no positions and “0”` lines and totals, as the performance read answers it. Nothing is persisted.
GET /api/v1/portfolios/:portfolio_id/income returns the retrospective income report: the dividends and interest already booked in the ledger, aggregated three ways (no forecast — the dividend calendar is a separate feature). annual is a list of years (newest first), each with months (a map keyed by month number "1"–"12", each carrying dividends and interest), and per-year dividends_total, interest_total and total. positions is the per-position table: security_id, security_name, security_currency (the original booking currency), gross, tax (the withheld tax, from the dividend’s TAX units stored on the transaction), net (gross - tax), payment_count and last_payment. transactions is the per-transaction detail for a year drilldown (kind, date, year, security_id/security_name, currency, the native native_gross/ native_tax/native_net, the base-currency gross/tax/net, and converted). A dividend’s gross is its net cash (gross_amount) plus the withheld tax; interest carries no withholding. All amounts are Decimal strings in the portfolio’s base_currency, converted via the EUR hub at each booking date’s stored rate (the same mechanics as the valuation endpoint), with the original currency retained; unconverted_count counts bookings with no rate path (converted at parity), and conversion_note states the basis. A booking’s cash and withheld tax are read in its cash account’s currency, the currency it was credited in (the ADR-0015 amendment of 2026-10-07): a dividend of a USD security credited to a EUR account is converted from euros, and its transactions row’s currency names EUR, the currency its native_* amounts are in, while its positions row keeps the booking currency in security_currency. Unknown portfolios return 404 Not Found. Since ADR-0020 a target plan belongs to a view: the target read/write endpoints accept an optional view (a view id). Omitting it (or sending null) addresses the portfolio-wide Gesamt plan — the behaviour before views existed. A view carries its own plan, so the same classification can hold a different plan per view without the plans summing across each other. A malformed view returns 422 Unprocessable Entity ({"view": ["is invalid"]}) and an unknown view id returns 404 Not Found, the same structured contract the analytics endpoints use.
GET /api/v1/portfolios/:portfolio_id/targets lists a portfolio’s stored target weights (the target side of the allocation). Optional classification_id scopes the list to one tree; optional view selects the plan (omitted = Gesamt). Unknown portfolios return 404 Not Found.
PUT /api/v1/portfolios/:portfolio_id/targets upserts target weights for one classification. The body is {"classification_id": id, "targets": [{"category_id": id, "target_weight": "0.25"}]} and may carry an optional "view": id to write that view’s plan (omitted = Gesamt). Each target_weight is a string fraction in [0, 1] with at most 6 decimal places (four in percent); a finer weight answers 422 on target_weight, and the database refuses it too unless the instance already held a finer weight when it was upgraded (the upgrade then logs how many). Duplicating a plan, or saving it in the SOLL editor, rounds such a stored weight half up to 6 decimal places. A weight refused for its precision or for lying outside [0, 1] also names its row, as the plan editor puts the refused row first: errors.row is {"category_id": id, "security_id": id}, with security_id null for a category row, beside errors.target_weight (issue #1143). Targets need not sum to 1. Only the supplied categories are changed. A category from another tree returns 422 Unprocessable Entity, and an unknown classification returns 404 Not Found. A batch names each category row once and carries at most one row per category and one per security assigned in the classification, and never more than 10000 rows; a repeated category row or a larger batch answers 422 (errors.detail naming the category, or errors.targets stating the bound) and writes nothing. Position-level SOLL (ADR-0030): a target entry that also carries a "security_id" sets a weight on that individual position under the category (the security must sit under it, else 422); a category entry (no security_id) and its position entries are stored side by side. A present security_id must be a positive integer or null (null = category row) — anything else (a non-numeric string, a float) returns 422 instead of being coerced into a category write. A plan carries at most one position row per security: filing a security under a second category, or naming the same (category, security) twice in one batch, returns 422. The database holds the rule as well, so a write that loses a race to file the security under another category answers the same 422 and stores nothing. Each serialized target carries security_id (null for a category row). A plan version (issue #1133): an optional "plan_id": id writes that plan version — a draft from POST /api/v1/plans/:id/duplicate, or the active plan — instead of the view’s active plan, so a draft’s category and position targets are edited over the API as in the SOLL editor, and activated when ready; the reads keep following the active plan. The plan must be one of this portfolio’s, of this classification and, when view is given, of that view, and it must not be archived: an archived version steers nothing and is reused by activating it or duplicating it into a draft. A malformed id, an unknown plan or another portfolio’s, another classification’s, another view’s and an archived one each answer 422 on plan_id (is invalid, is not a plan of this portfolio, is a plan of another classification, is a plan of another view, is archived: activate it, or duplicate it into a draft) and write nothing.
DELETE /api/v1/portfolios/:portfolio_id/targets/:category_id removes a portfolio’s category target for one category and returns {deleted} (the number of rows removed). Position rows for the category are left in place. Optional view selects the plan (omitted = Gesamt); optional plan_id addresses a plan version as on the PUT, with the same 422s.
GET /api/v1/portfolios/:portfolio_id/position_targets lists a portfolio’s position-level SOLL targets (ADR-0030): {"position_targets": [...], "effective_targets": [...]}. Each position_targets row is a target on a security under a category (with security_id and security_name); each effective_targets entry is a category’s roll-up — explicit (the category-row weight or null), position_sum (the sum of the position rows filed directly under it — descendants’ rows roll up to their own category), effective (the resolved steering weight — the position sum wins) and conflict (true when explicit and position sum disagree, surfacing the mismatch). Each position row also carries stale (true when its security no longer sits under the stored category — reclassified or unassigned; the row still counts where it was filed, re-filing is the remedy) and each roll-up has_stale. Weights are Decimal strings. Optional classification_id / view scope as above. Read ergonomics (FR-37, issue #740): min_drift= — the allocation read’s threshold, same spelling (a non-negative Decimal string on |drift_weight|) — returns only the position rows whose drift meets it, where drift_weight is the security’s actual weight in the steering basis minus its position target exactly as the allocation computes it (one predicate, two surfaces). Kept rows carry drift_weight; rows without a drift are filtered out; the response states the applied min_drift, position_targets_total (the pre-filter count) and a drift_basis sentence. Without min_drift the rows carry no drift_weight and the shape is unchanged. An invalid threshold is a 422.
DELETE /api/v1/portfolios/:portfolio_id/position_targets/:category_id/:security_id removes one position target and returns {deleted}. The category row and the category’s other positions are untouched. Optional view selects the plan; optional plan_id addresses a plan version as on the PUT.
GET /api/v1/portfolios/:portfolio_id/plans lists a portfolio’s SOLL plan versions (ADR-0027): active first, then drafts and archived plans, each with name, status (active / draft / archived), its scope (view_id, classification_id) and cash_target_weight as a Decimal string. Optional classification_id scopes to one tree; a value that is not an id is ignored, and every plan is listed. Only the active plan of a scope steers the allocation.
POST /api/v1/plans/:id/duplicate copies a plan version (category and position targets, and cash target) into a new draft of the same scope and returns it with 201 Created. Optional body {"name": "Plan 2027"} names the copy (default: "<source name> (copy)").
POST /api/v1/plans/:id/activate makes a draft or archived version the active plan of its scope, archiving the previously active plan in the same transaction. Activating the already-active plan is a no-op.
PATCH /api/v1/plans/:id renames a plan version ({"name": "..."}).
DELETE /api/v1/plans/:id deletes one plan version (any status) including its category and position targets. Deleting the active plan leaves the scope without a plan (the allocation falls back to actual-only). Each target is journaled as its own target delete before the plan’s target_plan delete.
GET /api/v1/snapshots lists depot snapshot markers (ADR-0027): each is a name, a scope (view_id, null = everything) and an as_of date. A snapshot copies no financial data — the holdings it represents derive from the transaction ledger on demand. limit keeps the newest snapshots (default 1000, max 10000); the answer echoes the applied limit.
POST /api/v1/snapshots creates a marker ({"name": "...", "as_of": "2026-02-15", "view_id": 3}; view_id optional). A future as_of or a duplicate name within the scope returns 422 Unprocessable Entity.
DELETE /api/v1/snapshots/:id deletes one marker; no transactions or holdings are affected.

Recorded tax statements (ADR-0031)

These pots are recorded, not derived — and the reason is not a missing FIFO. Portfolixir matches lots FIFO already (GET /api/v1/securities/:id/trades), and that gives a gross gain. A gross gain is not a tax pot: Teilfreistellung, Vorabpauschale, chronological allowance consumption and certified prior-year carry-forward are not in the transaction data at all, and the pots are kept per tax-reporting institution, which Portfolixir does not model. A derived pot would be wrong, and invisibly so — so these endpoints transcribe a broker statement, they never compute one from holdings. Every money value is a positive magnitude Decimal string: a loss pot is the volume of loss available for offsetting, not the negative number the statement prints, and a negative input is rejected rather than silently flipped. Nothing here is tax advice, and the recorded statement remains the authority. (A tax actually credited back to a cash account — for example after a loss sale — is a ledger event, not a pot: book it as a separate tax_refund transaction as described under “Transactions and Holdings” above.)

GET /api/v1/tax/parameters lists the year-scoped statutory parameters (optional jurisdiction, currently only DE): capital_gains_tax_rate, solidarity_surcharge_rate and the saver_allowance_single / saver_allowance_joint ceilings. Rates are Decimal string fractions ("0.25", never "25"). Seeded 2009–2026; a year with no row is simply absent — the API never substitutes a neighbouring year’s ceiling.
PUT /api/v1/tax/parameters inserts or replaces one year’s parameters ({"parameters": {"tax_year": 2027, ...}}).
GET /api/v1/tax/profiles lists a holder’s effective-dated tax profiles (required holder; a missing one returns 422 Unprocessable Entity), newest valid_from first. The profile in force for a date is the row with the greatest valid_from at or before it — never an exact match. Church-tax liability defaults to not liable with rate 0.
POST /api/v1/tax/profiles records a profile from a date ({"profile": {"holder": "...", "valid_from": "2024-01-01"}}). A non-zero church_tax_rate on a not-liable profile is rejected.
PATCH /api/v1/tax/profiles/:id corrects one profile row. To record a change in the situation, create a new row with a later valid_from — editing rewrites history, adding does not.
DELETE /api/v1/tax/profiles/:id deletes one profile row. Snapshots already recorded keep their frozen church-tax rate and are unaffected.
GET /api/v1/tax/allowance_orders lists the Freistellungsaufträge the taxpayer instructed (optional holder, institution, tax_year; free-text filters fold case, so comdirect and Comdirect are one institution). Every holder and institution the tax endpoints write or filter on is normalised one way — composed to NFC, invisible format characters removed, every run of Unicode spaces one space, a value that is only such characters a 422 — and matched by the database’s own case fold on both sides, the fold of the unique indexes (E25 S6).
PUT /api/v1/tax/allowance_orders records or replaces the instructed amount for one (holder, institution, tax_year) ({"allowance_order": {...}}).
DELETE /api/v1/tax/allowance_orders/:id deletes one configured order.
GET /api/v1/tax/statement_snapshots lists recorded statements (optional holder, institution, tax_year), newest as_of first. Each row carries the eleven recorded figures plus allowance_remaining, tax_free_trim_budget, expected_capital_gains_tax, the as_of they rest on, a stale flag, and the advisory findings. Each row also carries the activity-aware staleness assessment (#667): staleness as a function of activity, not only of the calendar. It states its own computation basis — age_days against age_threshold_days (90), activity_since_count (the ledger transactions of activity_kinds — sell, dividend, interest, tax, tax_refund — dated strictly after as_of), the two component warnings and the combined warning, plus a basis note recording that bookings are not attributed to an institution or tax year. warning is the signal to act on; the bare stale flag flips the day after any as_of and is kept for compatibility.
POST /api/v1/tax/statement_snapshots records a statement ({"statement_snapshot": {"institution": "...", "holder": "...", "tax_year": 2025, "as_of": "2025-12-31", ...}}). as_of must not lie in the future. Omit church_tax_rate to take the holder’s profile in force at as_of; the resolved rate is then frozen on the row, so a later profile edit never rewrites a recorded transcription. Re-recording the same (institution, holder, tax_year, as_of) is a 422, not a silent duplicate. A recorded statement’s source is manual, set by the system: a source in the body of a create or a correction is ignored.
GET /api/v1/tax/trim_budget rolls the latest statement per institution up to one holder and year (required holder and tax_year); institutions are grouped by the database’s case fold, so a later statement under another case spelling of one bank replaces the earlier one. It reports which institutions it covers, the as_of of its oldest component, the summed allowance_granted and allowance_used the fill level on the Tax page is read from (beside allowance_remaining), and complete: false with missing_institutions when a configured allowance order has no recorded statement for the year — the total is then a partial picture and says so. The response carries the same staleness assessment, computed against the roll-up’s (oldest) as_of.
GET /api/v1/tax/statement_snapshots/:id reads one recorded statement.
PATCH /api/v1/tax/statement_snapshots/:id corrects one recorded statement in place — the re-issued-statement case.
DELETE /api/v1/tax/statement_snapshots/:id deletes one recorded statement.

Consistency findings are advisory and computed at read time. A finding names the recorded and the expected number and the gap; it never proposes a corrected value and never blocks a write. Two rules are hard instead, and come back as 422 changeset errors: allowance used above allowance granted, and church tax withheld at a zero church-tax rate.

GET /api/v1/portfolios/:portfolio_id/snapshots/:id/comparison answers “would I have done better keeping what I had?”: the snapshot’s frozen holdings valued buy-and-hold over the stored quote history (daily, EUR-hub FX) against the scope’s real TTWROR since the as-of date. The response carries as_of_value, current_value, snapshot_return, real_ttwror, a daily series (snapshot_value, snapshot_indexed, real_indexed), a gaps.unvalued_securities list of securities excluded for missing quotes or FX at the as-of date, and a self-describing basis (gross, price-return only in v1; it carries the window, the base_currency, and costs_removed / costs_kept naming which cost kinds left the return). All financial values are Decimal strings.

The two sides are not on one basis, and the payload says so (#708, ADR-0027 amendment): the frozen side pays nothing ever, while the real TTWROR is net of the fees and taxes actually booked. The response therefore also carries real_ttwror_before_costs (the same walk with the window’s trade fees and taxes reclassified as external flows — standalone fee/tax bookings and dividend withholding deliberately stay inside the return, because the frozen holder would have paid those too), transaction_costs (their total in the base currency) and cost_recovery with state one of recovered, partly_recovered (ahead before costs, not yet after; outstanding states the gap), not_recovered (behind even before costs, so the costs are not the reason) or not_comparable (the frozen side has no value at the as-of date — an all-cash snapshot, for example — so there is nothing to be ahead of; the costs still report). Read the three together: real_ttwror_before_costs alone flatters.
GET /api/v1/portfolios/:portfolio_id/category-results?classification_id=<id> — per-category result (ADR-0041 slice one, #712): invested (the sum of the members’ base-currency cost), current_value, result_abs and result_pct per category, plus the member positions that produced it and the excluded rows it could not cover.

Read the basis before the numbers. The payload states it in one line (basis: "current_composition", with a basis_note spelling it out): this is a figure about the positions filed under each category today, so there is no period, no membership variant and no as-of — and it is not a time-weighted return series.

result_pct is Σ result ÷ Σ invested, never a mean of the members’ percentages: averaging lets a tiny position at +300 % dominate a category that is flat in money. A member whose result is not derivable — no usable price, or no base-currency decomposition (ADR-0033) — is excluded from both sides of the sum and listed under excluded with its reason; it is never counted as zero, which would quietly understate the category. covered_count and member_count state how much of the category the figure covers. A category with nothing invested reports result_pct: null rather than "0", because having nothing to measure is a different claim from being flat. MCP: portfolixir.portfolios.category_results.

The view scope (#901) comes in the performance family’s two forms (ADR-0051 §6). ?view=<id> narrows the portfolio read to the portfolio’s positions matching that view and echoes it as view: {id, name}; a malformed view is a 422, an unknown one a 404. The view read below spans every portfolio, and GET /api/v1/category-results every portfolio with no view (#1091). Every answer states the scope it was computed over: scope (portfolio, view or all), portfolio_id, view_id, base_currency (the currency of every money figure: the portfolio’s on the portfolio read, EUR on the view read and on the every-portfolio read, scope: "all"), and a closing sentence of basis_note that names it. The MCP tool takes the same scope: portfolio_id, which view narrows, view alone for the view across every portfolio, or neither for every portfolio.

Every form names what it leaves out once (#1091): excluded_members lists each excluded member a single time across the tree, however many levels it rolls into, sorted by name without regard to case (ties by security_id), with security_id, security_name, category_id (the category it is filed under), reason and native_costs — [{amount, currency}], the cost in the currency it was paid in, amounts as Decimal strings, when only that currency keeps it out of a EUR sum, and [] otherwise. A security held in a EUR and a non-EUR portfolio is left out whole and carries one entry per currency, the result’s currency first, then the others by code. Every basis_note names the list; the per-category excluded rows are unchanged.
GET /api/v1/portfolios/:portfolio_id/allocation returns the target/actual breakdown for one classification (required classification_id query param; a missing one returns 422 Unprocessable Entity). For each category it reports parent_id and depth (the categories form a tree), color, own_market_value (positions assigned directly to it), market_value (its whole subtree rolled up), actual_weight (the rolled-up share of total_value), target_weight, drift_weight (actual_weight - target_weight: positive = overweight, negative = underweight; ADR-0023), and drift_value (the drift restated in the base currency — how much to sell (positive) or buy (negative) to reach the target). Each row also carries child_target_sum (Decimal string): the advisory sum of its direct children’s targets, or null when no direct child carries a target — a target-consistency hint the UI can flag against the row’s own target_weight. A position assigned to a child counts toward that child and every ancestor, so a parent category with a target is compared against its subtree rather than showing 0%; the rows come back in tree order (parent before its children). Because parents aggregate their children, the per-category actual_weight values intentionally do not sum to 1 across levels — only the leaves plus unassigned do. Each category (and unassigned) also carries positions: the per-security breakdown of its own (directly assigned) value — security_id, security_name, quantity, market_value, weight, plus the display-only rebalancing hints (ADR-0023): drift_value (the position’s proportional share of the category drift) and rebalance_quantity (indicative units to sell (positive) or buy (negative) at the valuation’s implied base-currency unit price; no fee/tax modelling, never an order). Both hints are null without a plan, for unassigned positions without their own position SOLL, and for a position valued at 0 without its own SOLL, which holds no share of its category’s drift (E25 S4); the page shows “—” and sorts such a row after the rows that drift. With the position rows, the payload’s computation_basis states the drift share’s basis (drift_value) and lists these gaps. Entries come largest first, securities merged across depots; this is what the sunburst’s outermost ring renders. Position-level SOLL (ADR-0030 slice 2a): a category’s positions are the union of its held positions and the active plan’s position-target rows, matched by security. Each entry additionally carries target_weight (its position SOLL, null when none), drift_weight (actual weight − target weight, ADR-0023 sign) and held. An entry with its own SOLL derives drift_value and rebalance_quantity from that own drift instead of the category share. A position with SOLL > 0 that is not yet held appears with IST 0 (held: false, quantity/value/weight "0") and full underweight drift — “this needs buying” — with its indicative quantity priced at the latest stored quote (null when no price exists; none is invented); quote_date names that quote’s date (null when the hint is not quote-based). held means holdings presence: a held security whose price cannot be determined is never reported as unheld (it stays on the unvalued surfaces instead). Each entry also carries stale (true when its attached position-target row no longer matches the security’s current category). A position is hidden only when its SOLL is 0/absent and its holdings are zero. Each category row also carries conflict (its explicit weight and position sum disagree — the sum steers) and has_stale (a position row filed under it is stale), and the breakdown carries deep_target_sum — the effective targets’ sum at the topmost targeted level per subtree, which explains a 0 top_level_target_sum over a plan steered deeper in the tree. Securities held but not assigned in the tree are summed into unassigned; unassigned entries attach their position SOLL too. Weights are shares of the steering basis: the valued positions’ total (scoped by the active view when one is passed), plus the deployable cash (free_cash accounts with a non-negative balance). total_value here is that steering basis (not the full valuation). The response carries a cash object — market_value (the counting cash), actual_weight (its share of total_value), target_weight (the active view’s plan cash target, or 0 when unset; see the cash-target endpoints below), drift_weight (actual_weight - target_weight, ADR-0023), drift_value (restated in the base currency), and distributed (boolean) — so cash is steered in the same drift logic as the categories. When the active classification is the built-in currency tree, each cash account’s deployable balance is attributed to its own currency-code category instead of appearing as a separate cash row: EUR cash flows into the EUR category, USD cash into USD, and so on. In that case cash.distributed is true and consumers should omit the separate cash row; for all other classifications distributed is false and the cash row behaves as before. Because cash is part of the 100% basis, the category percentages shrink accordingly once cash is present. The top_level_target_sum is the sum of the root categories’ targets plus the cash target (except for the currency classification where cash is distributed into categories), compared against 1. A plan may deliberately allocate less than 100%: unallocated_remainder states that gap (1 − top_level_target_sum, "0" when the plan is full) and drift_basis names what the drift figures were measured against — "allocated_portion" when each target was renormalised to the allocated share first, so the unsteered remainder is not reported as phantom overweight, and "full_plan" when the plan sums to 100% and drift is the plain actual − target. The remainder is computed on read, never stored (ADR-0040). To keep a holding out of the steering basis while it still counts toward total wealth, tag it with a bucket and exclude that bucket from the view the allocation is read under — it then falls outside the scoped positions. Since ADR-0020 the target side reflects the active view’s plan: passing view=<id> reports that view’s target weights, cash target and top_level_target_sum (omitting it uses the Gesamt plan), so the drift table steers against one coherent 100% plan per view. Category target_weight values are the effective targets (ADR-0030): the sum of a category’s position rows when any exist (positions are the source of truth), else its explicit category weight — the Σ figures consume the same effective values. For the raw position-target rows and per-category roll-up (the maintenance view) use the position_targets endpoint above. Unknown portfolios or classifications return 404 Not Found. Read ergonomics (FR-37): include_positions=false omits the per-category (and unassigned) position rows for a roll-up-only read, and min_drift=<decimal> (an absolute drift-weight threshold, e.g. 0.02) returns only the category rows whose |drift_weight| meets it — targetless categories carry no drift and are filtered out with it, and kept rows come back flat (an ancestor under the threshold is absent). The response states its own basis: positions_included, the applied min_drift and categories_total (the pre-filter category count). Invalid values are a 422, and so is a value that is not a finite decimal (NaN, Infinity), here and on position_targets. The allocation page carries the same filter as its drift-threshold chips (one shared predicate, so the two surfaces cannot select different categories); the chips speak percentage points, so ≥ 5 pp on screen is min_drift=0.05 here. tax_context=true (#667) additionally attaches the current-year tax-free trim budgets — one entry per holder identity with recorded statements (case spellings of one taxpayer are one entry), each with its activity-aware staleness — so the tax headroom is readable where the trim decision is made; the block states that it rolls up per (holder, tax_year) across institutions and is never scoped to the portfolio or view.
GET /api/v1/portfolios/:portfolio_id/risk returns a risk/concentration lens for one portfolio over the steerable basis (the valued positions, scoped by the active view, the same basis the allocation drift uses). A security held across several depots is merged into one single-name exposure. Weights, caps and the HHI are all on a 0-100 percentage scale (Decimal strings, full precision, no rounding):
- steerable_basis is the basis the weights are a share of, and base_currency the portfolio’s base currency.
- top_holdings is the largest single-name exposures, largest first, default N = 10 (override with the top_n query param). top_n keeps the list reads’ capped-and-echoed contract: at most 1000, a larger value is capped, and the answer echoes the applied top_n (E25 S4). Each entry carries security_id, security_name, asset_class, market_value, weight and a severity (ok/warn/hard). The severity is instrument-type aware: a single stock warns above 7 and goes hard above 10; an ETF (the etf asset class) warns above 25 and never goes hard. Override the defaults with the stock_thresholds[warn]/stock_thresholds[hard] and etf_thresholds[warn] query params.
- hhi carries the Herfindahl-Hirschman Index of the single-name weights (value = the sum of the squared percentage weights, on the 0-10000 scale) plus a band: low (< 1500), moderate ([1500, 2500]) or concentrated (> 2500). Override the cutoffs with the hhi_bands[low] and hhi_bands[high] query params.
- asset_class_violations are opt-in asset-class cap violations: there are no shipped defaults, so caps are configured per call with the asset_class_caps[<asset_class>] query param (a percentage, e.g. asset_class_caps[equity]=50). Only classes whose current percentage weight exceeds the cap come back, each with asset_class, current_weight, cap and overage (current − cap, in percentage points).
The lens is a pure read-time derivation of the live valuation and the securities’ asset classification — nothing is stored, so it is deterministic on read. A malformed override (e.g. a non-positive top_n) returns 422 Unprocessable Entity; unknown portfolios return 404 Not Found.

The portfolio’s derived metrics ride the same read (ADR-0047, FR-40, scope-ladder level (a)) under metrics, additively. The risk family has exactly one endpoint: there is no /views/:id/risk, and the view arrives as the view parameter the lens already honours.
- volatility, max_drawdown (with peak_date, trough_date, recovery_date) and risk_adjusted_return, each over 30d, 90d and 365d. They read the flow-adjusted daily return factors of the TTWROR chain — never the day-over-day change of the portfolio’s value — so a deposit or a withdrawal is not a return: a portfolio whose prices never move has volatility and drawdown exactly 0 however much money moves in and out. A walked day whose return base is zero or negative produces no observation rather than a zero return. Volatility is the population standard deviation of the daily returns, annualized by √365 (the walk is a calendar walk); the drawdown runs over the chained return index.
- risk_adjusted_return is the mean daily excess return over the risk-free leg, times 365, divided by the annualized volatility. The risk_free_rate query parameter is a Decimal fraction (0.02 is 2 % p.a.), compounded daily as ADR-0046’s fixed-rate benchmark is, bounded like it, and defaults to 0 — at the default the figure is return per unit of risk, and computation_basis.reference says so. No rate is inferred, fetched or stored; each window echoes the rate it used. A malformed or out-of-bound rate is a 422. Over a volatility of exactly 0 the ratio is null without insufficient_data: undefined, not short of data.
- A figure whose square root lies beyond what the one float step can carry — a magnitude only implausible stored prices or exchange rates reach — is null without insufficient_data as well: that volatility and the risk-adjusted return beside it, or that correlation pair. The read never fails on such data, and never answers a number over it; the Risk page shows such a pair as “not computable” with its observations.
- correlations is the Pearson matrix of the daily returns of at most the 20 leading Top-N single names (leading_names states how many it ran over; the pair count grows with the square of the names, so the matrix is bounded while the list is not, and computation_basis says so), with security_ids in Top-N order and pairs with security_id_a, security_id_b, value, over a 365d window. The closes are converted to the base currency first — the opposite of the per-security metrics, because two holdings sharing an FX leg do move together in the operator’s money — and a pair reads only the days on which both securities have a stored close. A security whose currency has no stored rate path is absent from the matrix and listed in excluded with reason: "no_rate_path", never silently unconverted.
- Every metric carries window, observations, required and insufficient_data; below its minimum — 20 observations for volatility and the risk-adjusted return, 2 index points for the drawdown, 60 overlapping returns per correlation pair — value is null at 200. metrics.computation_basis carries input_series, window, reference, gaps and assumptions once; figures are ratios rounded at scale 6.
- The read reports; it does not evaluate. No key in metrics is a signal, recommendation, rating, score or action, and a meta-test walks the rendered key set of both metric payloads to keep it so.
GET /api/v1/portfolios/:portfolio_id/cash_target reads a plan’s cash target, the target cash share of the allocation’s 100% basis (securities + counting cash). The response is {"cash_target_weight": "0.05"} (a string fraction in [0, 1], or null when none is steered). Optional view selects the plan (omitted = the Gesamt plan). Unknown portfolios return 404 Not Found, a malformed view returns 422, and an unknown view id returns 404.
PUT /api/v1/portfolios/:portfolio_id/cash_target sets (or clears with null) a plan’s cash target. The body is {"cash_target_weight": "0.05"} and may carry an optional "view": id (omitted = Gesamt). It echoes the stored value back. Out-of-range weights, and weights with more than 6 decimal places, return 422 Unprocessable Entity on cash_target_weight, beside errors.row "cash", the row the plan editor names (issue #1143). The cash target feeds the allocation’s cash row and the top_level_target_sum for the addressed view.
PATCH /api/v1/portfolios/:portfolio_id patches a portfolio’s master data. Deprecated (ADR-0024) — answers with Deprecation: true; compatibility only, use buckets/views for grouping. The body is {"portfolio": {...}}. Cash target move (ADR-0020): the cash target moved off the portfolio object onto the per-view target plan, served by the two cash_target endpoints above. For back-compatibility the portfolio object still exposes cash_target_weight — a string fraction in [0, 1] (e.g. "0.05" for 5%), or null to stop steering a cash quote — and patching it reads/writes the Gesamt plan’s cash target (view omitted). So a client that only knows the old field keeps working unchanged; use PUT /cash_target?view=<id> to steer a per-view cash target. Out-of-range weights return 422 Unprocessable Entity; unknown portfolios return 404 Not Found. The cash target is written only when the body carries cash_target_weight, in the same transaction as the rest of the patch: a patch without it (a rename, say) leaves the stored cash target and its journal untouched, and a refused cash-target write answers 422 with nothing written, the rest of the patch included. The response carries the cash target as stored after the write. The cash_target_weight is also included in the portfolio objects returned by GET/POST /api/v1/portfolios (the Gesamt cash target).
GET /api/v1/securities/:security_id/trades returns FIFO-matched trades for one security: open lots, closed round-trips (with realised P&L and holding period in days) and any orphan sells. Each open lot carries buy_price (as recorded, transaction currency) plus buy_price_native — the security-currency basis its unrealized_pnl_* is computed against (ADR-0033) — and the same base-currency decomposition fields as the holdings rows (base_cost, price_return_*, currency_return_*, total_return_base_*, decomposed/undecomposed_reason, against the EUR hub, since FIFO lots are matched per security across portfolios). A lot with no derivable native leg reports null P&L instead of a blind cross-currency figure. The response is self-describing (FR-13): it carries method: "fifo", so a client never has to assume how lots were paired against sells. Optional from/to (ISO dates) filter each leg by its own date: open lots by open date, closed round-trips by close date, orphan sells by sell date. There is no limit: from/to are the bound (the FIFO matcher needs the whole history, and each leg is filtered by its own date afterwards), stated in the payload’s basis. Since issue #984 every closed round-trip carries annualized_return and annualized_return_reason, the same figure and rule as the realized-gains read above, and the payload carries computation_basis.annualized_return. Since issue #1108 an open lot’s buy_fees and buy_taxes and a closed round-trip’s buy_fees, buy_taxes, sell_fees and sell_taxes are in its currency_code, like its basis and proceeds: a cross-currency trade booked in the security’s currency converts them from the cash account’s currency at its own stored settlement_fx_rate, as the realized-gains read above describes, and computation_basis.fees_and_taxes states the rule. Since issue #1142 a closed round-trip whose basis is "0" reads realized_pnl_pct null with annualized_return_reason no_cost_basis, as on the realized-gains read, and an open lot whose cost (quantity × buy_price_native) is "0" keeps its unrealized_pnl_abs and reads unrealized_pnl_pct null, never "0"; computation_basis.realized_pnl_pct and computation_basis.unrealized_pnl_pct state the rules. As on the holdings read, an open lot whose base_cost is "0" reads the decomposition’s three percentages null too, and computation_basis.decomposition_pct states the rule.

Policy rules (ADR-0049)

A policy rule is a stored standard over a figure the product already serves: “no single name above 10 %”, “cash never below 5 %”, “the bond category within ±3 percentage points of its target”, “the portfolio’s 90-day volatility under 15 %”. It is stored as an object instead of living as prose in a scheduled prompt, which is where such limits used to drift. The operator writes rules on the Risk page and an agent writes them over the API with its token, so a rule is a stored rule whoever wrote it: the audit journal (resource_type policy_rule and policy_rule_version) says who wrote each rule and each version, and the list’s rules_note points there. Every version also carries author (E25): operator for a version saved on the Risk page, agent for one written with an API or MCP token, derived from the write’s credential and never read from the body; a finding carries the author of the version in force. A version stored before authors existed takes the author its journaled creation names, null only without one. Risk marks the agent’s rules with the word “Agent”; when a rule is in force does not depend on its author.

What a rule is. A predicate over one named measure, for one subject, in one evaluation context:

the context is the portfolio plus an optional view_id (null is the portfolio-wide context, the convention target plans use); the measure is read on that context’s steerable basis;
the subject is basis, security (security_id), category (classification_id + category_id), view (subject_view_id) or cash;

the measure is one of these, and each is read off a payload the product already serves — the rules compute no figure of their own:

`measure`	Subjects	Scale of the thresholds
`weight`	security, category, cash, view	percent, `0`–`100`
`drift`	category, security	percentage points, `−100`–`100` (actual − target of the active plan)
`hhi`	basis	`0`–`10000`
`volatility`	basis, with a `window` (`30d`, `90d`, `365d`)	percent, annualized, `≥ 0`
`max_drawdown`	basis, with a `window`	percent in its own sign, `−100`–`0`

A security subject read for drift also names the classification_id whose plan carries its position target. A view subject is how a bucket is capped: “the speculative bucket stays under 5 % of everything” is a weight cap on the view that selects that bucket, evaluated in the portfolio-wide context.

the kind is cap (breached strictly above threshold), floor (strictly below) or band (outside [lower, upper]) — the risk lens’s own reading of a line, so a rule and the lens never disagree about where one is;
the severity is warn or hard; name and note are the rule’s words, whoever wrote them, and are never parsed. The name is a label on the rule, not part of its identity: it can be changed at any time without a new version (see the rename below), and it need not be unique.

Thresholds are Decimal strings (ADR-0016). A predicate that does not fit its measure — a subject outside the matrix, a missing or superfluous window, a band with lower > upper, a threshold off the scale — is a 422 naming the field under version.

Versioned and effective-dated. A rule has a stable identity and one or more versions, each the standard of its own period [valid_from, valid_until]. An edit adds a version from valid_from (today by default, never earlier) and closes the previous one the day before; both stay readable, so “what was the standard on date D” is a read (as_of=), not an investigation of the audit journal. A version that has been in force is never changed and never deleted — the database refuses it, and refuses two overlapping versions of one rule. A version only scheduled for a later date is replaced by adding a version from the same date. The database also refuses, on any version, a change to its rule, its predicate or its start date; on any rule, a change to its portfolio or view; and a TRUNCATE of either table. A version’s end date and a rule’s name stay writable, through the retirement, the edit and the rename. Every write is journaled.

The reads:

GET /api/v1/portfolios/:portfolio_id/policy_rules — the portfolio’s rules, each with status (in_force, scheduled or retired, relative to as_of), version_in_force and next_version. as_of (ISO date, default today) reads the standard in force on a date; include_retired=true adds the retired rules; view narrows to one evaluation context (absent: every context); since is the row delta (a rule counts as changed when its row or any of its versions did); limit (default 1000, max 10000).
GET /api/v1/policy_rules/:id — one rule with its whole version history, oldest first.

The writes:

POST /api/v1/portfolios/:portfolio_id/policy_rules — body {"rule": {"name", "view_id", "version": {…}}}; creates the rule with its first version (201).
POST /api/v1/policy_rules/:id/versions — body {"version": {…}}; the edit (201). On both, a version’s note holds at most 10000 characters (Unicode code points); a longer one answers 422 on note.
PATCH /api/v1/policy_rules/:id — body {"name": "…"}; the rename, a rule-level edit outside the versioning: no version is added or changed, and the new name reads for the rule with all its versions (200, the rule with its versions). The journal keeps the previous name and who changed it. Allowed on a retired rule. Only name is read, as on PATCH /api/v1/plans/:id: a blank, missing or non-text name is a 422 on name; a predicate field, a version, the version keys of the rule’s own read shape (version_in_force, next_version, versions) or the context (view_id, portfolio_id) in the same body is a 422 naming each such field, and nothing is written — a new line is a new version, and a rule in another context is a new rule. Any other key is ignored. A rule deleted since it was read is a 404.
POST /api/v1/policy_rules/:id/retire — optional valid_until; ends the version in force yesterday by default (tonight when it only started today) and drops any version scheduled after it. The rule stays readable with include_retired=true. A rule none of whose versions has been in force, or one already retired, is a 409.
DELETE /api/v1/policy_rules/:id — only while no version has ever been in force (204); otherwise 409, and the remedy is retiring it.

A new version, a retirement and a delete each hold the rule while they read its versions, so two of them on one rule take turns: a version added while a retirement runs waits for it and is judged against the retired rule, never surviving it. A rule deleted since it was read is a 404 on all three.

What a rule reads is protected. Deleting a security, a category, a classification or a view that a rule version (or a rule’s context) references answers 409 with errors.policy_rules — each rule’s id, name and status — and a detail naming each rule by its id and status (policy rule(s): #7 (in_force)), never by its name (#965), and stating the remedy. A version that has been in force keeps its subject as the record of what the standard was, so retiring the rule stops its evaluation but does not free the object; only a rule none of whose versions was ever in force can be deleted, which does. A security stays retirable (is_retired) as before.

The findings read. GET /api/v1/portfolios/:portfolio_id/policy_findings evaluates the rules in force today for one evaluation context (view; absent: the portfolio-wide rules) over the figures the product already serves, and answers one finding per rule, sorted breached, undetermined, ok:

state is breached (strictly beyond the line), ok, or undetermined — the figure could not be read. Undetermined is never a pass and is never filtered out by default; it carries its reason: insufficient_data (a refused portfolio metric, with ADR-0047’s required and observations), undefined, no_active_plan or no_target (a drift with nothing to drift from), empty_basis (a weight of nothing is not 0 %), unvalued (the subject is held but its position cannot be valued, e.g. a quote with no stored exchange rate), subject_not_found or not_measured. A security that is simply not held has a weight of 0, which is a reading.
each finding carries the rule’s identity and words, the version, the thresholds, the measured value and the signed distance to the nearest line (value − line, on the measure’s scale), and its own computation_basis naming the read it used; the payload carries summary (a count per state) and a computation_basis stating the input series, window, reference and gap treatment.
status narrows to a comma-separated set of states: status=breached is the retrievable alarm list. It is a pull; nothing is pushed anywhere. An unknown state is a 422; since deliberately does not apply, because findings are a derived projection rather than rows.

The measures are read, never computed: the risk lens’s single-name weight and HHI, the allocation breakdown’s category and cash weight and the drift of the active plan (fractions × 100), the valuation for a view’s share, and the portfolio metrics’ volatility and maximum drawdown at the rule’s window (ratios × 100). The read is memoised under the portfolio’s data version and its rules counter, so an edited cap is evaluated on the very next read.

What this surface is not. A rule is a standard, never an instruction, and a finding carries no action — no quantity, no trade verb, no suggestion; a meta-test walks the rendered payload to keep it so. Nothing here places, proposes or sizes a trade, nothing is pushed anywhere, and no rule is replayed over a period before its valid_from (that would be backtesting, scope-ladder level (d)).

Exchange Rates

GET /api/v1/exchange_rates lists stored exchange rates. Rates are kept against the EUR hub (1 base_currency = rate quote_currency); other pairs are derived by triangulation, and GBX (pence) is handled as GBP × 100. limit keeps the most recent rates (default 50000, max 200000). Every stored rate is bounded like a quote: positive, and dated no later than tomorrow. A sync drops a provider rate outside the bound instead of failing the run, and the latest-rate reads never use a stored row dated past it.
POST /api/v1/exchange_rates/sync fetches rates from the configured provider (ECB by default) and returns {provider, status, upserted, scope}. scope=latest (the default) fetches the daily feed — today’s rates, nothing in the past. scope=history (issue #737, Sprint 9 D-1) runs the one-shot backfill of the historical ECB series (eurofxref-hist.xml) through the same upsert path: every published day at once, so a dated conversion (a realized gain, a cost or a flow the Cash-flow facets excluded and named for a missing booking-date rate) can find its rate. The rate-availability rule is unchanged — a day the ECB did not publish (a weekend, a currency it does not list) stays excluded and named; the backfill fills dates, it does not relax the “exact booking-date rate” basis. An unknown scope is a 422, a provider without a history answers 422 naming scope, and a provider failure, or rates the database cannot store, returns 502 Bad Gateway with nothing stored. One backfill runs at a time: while one runs, a second answers 409 Conflict. The human view is the Backfill historical rates control inside the exclusion notes on /cashflow. Since issue #1120 (Sprint 20 D-5) the instance also runs this backfill by itself, once, after its boot sync and after an import, when a booking or a cash account in a non-EUR currency predates that currency’s earliest stored rate, unless background fetches are off (PORTFOLIXIR_BACKGROUND_FETCH=off). scope=history remains for a manual run: where the automatic one could not reach the provider, on an instance with background fetches off, or for any other reason to refetch; while the automatic one runs it answers 409 like any second backfill. No parameter is added and no tool changes.

Classifications

Classification trees organise securities like folders. Built-in trees (asset_class, currency) are derived automatically and their structure is locked; editing the structure of a built-in tree returns 422 Unprocessable Entity. The asset-class tree’s membership, however, is just a view of each security’s asset_class field: in the UI a security is dragged between its categories (which sets that field), and the same effect is achieved over the API with PATCH /api/v1/securities/:id ({"security": {"asset_class": "etf"}}) or the securities.update MCP tool. Set it to empty/null for “automatic”, which re-infers the class from the security’s name/ISIN/ticker on read. The currency tree stays intrinsic and cannot be reassigned.

GET /api/v1/classifications lists every classification as a tree with its categories and assignments ({security_id, category_id}). Built-in trees carry built_in: true and a key.
POST /api/v1/classifications creates a custom classification from a classification object (name, optional position, description).
PATCH /api/v1/classifications/:id updates a custom classification’s classification object (name, position, description — all optional).
DELETE /api/v1/classifications/:id deletes a custom classification with its categories, its stored assignments and every plan on it with the plan’s targets. Each of those rows is journaled as its own delete before the classification’s; no row goes by database cascade alone.
POST /api/v1/classifications/:classification_id/categories adds a category (name, optional color, description, parent_id, position) to a custom classification.
PATCH /api/v1/classifications/:classification_id/categories/:id patches a category (name, color, description, parent_id, position — all optional). The category’s classification_id cannot be changed this way. On both writes a parent_id must name a category of the same classification that is neither the category itself nor one of its descendants; any other parent answers 422 on parent_id and nothing is written, so a tree never loops (E25 S4). A tree has at most 32 levels: a parent under which the written category, or the deepest category of the subtree a PATCH moves, would sit below level 32 answers 422 on parent_id as well, naming the level (“would put a category on level 33; a classification has at most 32 levels”, issue #940).
DELETE /api/v1/classifications/:classification_id/categories/:id deletes a category with the categories below it, the securities assigned there and the targets filed under them; each row is journaled as its own delete, the lowest categories first and the category itself last.
PUT /api/v1/classifications/:classification_id/assignments assigns a security to a category (security_id, category_id), replacing any existing assignment for that security in the classification. The response carries a status of created, moved, or unchanged plus previous_category_id.
PUT /api/v1/classifications/:classification_id/assignments/bulk assigns many securities to one category in a single call (category_id, security_ids), returning {assigned, category_id, security_ids}.
DELETE /api/v1/classifications/:classification_id/assignments/:security_id removes a security’s assignment from the classification.

Example transaction payload:

{
  "transaction": {
    "portfolio_id": 1,
    "securities_account_id": 1,
    "security_id": 1,

    "date": "2026-05-15",
    "quantity": "10.00000000",
    "price": "123.45",
    "fees": "1.50",
    "taxes": "0",

  }
}

Buckets and Views

Buckets are overlapping tags applied to holdings (depots, cash accounts and individual security positions) for tag-based wealth scoping. Views are named, global filters over those buckets: a holding matches when it is included (always under include_all, otherwise when it carries one of the view’s include buckets) and carries none of the view’s exclude buckets — exclude always wins. Bucket-definition and assignment writes are journaled (ADR-0017). A view’s definition is journaled too (ADR-0018 §5 as amended in Sprint 16), because a policy rule in force reads it: PATCH /api/v1/views/:id, PUT /api/v1/views/:id/buckets and DELETE /api/v1/views/:id each leave one resource_type=view entry, filed under the view, whose before and after carry the whole definition — name, include_all, include_bucket_ids and exclude_bucket_ids; resending the stored definition leaves none. Creating a view is not journaled: no rule can read it yet.

GET /api/v1/buckets lists buckets (id, name, color, dimension). dimension is "tag" (a free overlapping tag) or "scope" — the exclusive dimension: a depot or cash account carries at most one scope bucket, so scope-scoped totals always add up (ADR-0024).
POST /api/v1/buckets creates a bucket from a bucket object (name required, optional color, optional dimension defaulting to "tag"). A blank or duplicate name, or an unknown dimension, returns 422.
GET /api/v1/buckets/:id returns one bucket; unknown ids return 404.
PATCH /api/v1/buckets/:id patches a bucket’s name/color. The dimension is fixed at creation; attempts to change it return 422.
DELETE /api/v1/buckets/:id deletes a bucket (204 No Content). It is first removed from every view and assignment that names it, each through its journaled writer, so each affected owner gets its own entry: every view’s sets before and after, every depot default set and cash-account set, every position override. A position override whose only bucket this was stays explicit-empty (“no buckets”) and does not inherit its depot’s buckets, so the position enters no view it was not in. The bucket’s own delete entry carries its row and every membership it had (memberships: view_include, view_exclude, depot_defaults, cash_accounts, position_overrides). A bucket a policy rule’s view reads is deleted too; a bucket already gone answers 404. Removing the bucket from a set never re-checks the exclusive scope dimension, so a set stored before that rule held never blocks the delete; a set the bucket cannot be removed from answers 422, and nothing is deleted.
GET /api/v1/views lists views. Each view carries include_all, the resolved include set (the literal "all" under include_all, otherwise a list of bucket ids) and the exclude list of bucket ids.
POST /api/v1/views creates a view from a view object (name required, optional include_all defaulting to true).
GET /api/v1/views/:id returns one view with its resolved filter.
PATCH /api/v1/views/:id patches a view’s name/include_all.
DELETE /api/v1/views/:id deletes a view and its bucket sets (204); the plans scoped to it, with their targets, and its depot snapshots are journaled one delete each before the view’s.
PUT /api/v1/views/:id/buckets replaces a view’s include/exclude bucket sets. Body: {"include": [..], "exclude": [..]} (both optional, default [], arrays of bucket ids). A malformed id list returns 422; a bucket named twice in one list counts once.
GET /api/v1/views/:view_id/valuation returns the live valuation of a view across all portfolios (ADR-0024): the deduplicated union of every depot, position and cash account matching the view — an account tagged into several included buckets counts exactly once. The shape mirrors the portfolio valuation (totals, positions with weights and price_source/valued flags, cash_balances, cash_quote, unvalued_cash_count, as_of, a valuation_note) with view_id in place of portfolio_id, the count covering the cash accounts matching the view; totals are in EUR, converted via the EUR hub, and all financial values are Decimal strings. An overlap object reports the account-level bucket overlap for UI badges (overlapping, plus the securities_account_ids/cash_account_ids carrying more than one included bucket — the totals are already deduplicated). The active view is echoed as view: {id, name}. Unknown and malformed view ids return 404. include_positions=false (FR-37, issue #740 — the same parameter the portfolio valuation has) returns the roll-up only: totals, cash balances and cash quote without the per-position rows, and the response states positions_included. An invalid value is a 422.
GET /api/v1/valuation returns the total across every portfolio with no view (#1007): the unscoped union of every depot, position and cash account, each counted once, always in EUR, and the first figure a fresh instance can answer, since it has no view yet. It equals the dashboard’s total when the first portfolio’s base currency is EUR and no default view is set; the dashboard values its card in that currency and follows the default view, so otherwise the two can differ. The shape is the view valuation’s with view_id: null and no view echo (overlap reports no overlap, matches_no_accounts is false), and the valuation_note names the scope. include_positions=false returns the roll-up only, as on the view read; an invalid value is a 422. MCP: portfolixir.views.valuation without an id. The performance, the benchmark comparison and the contribution analysis have the same view-less form (#1056), listed after their view reads below.
GET /api/v1/views/:view_id/performance returns the view’s TTWROR and money-weighted IRR across all portfolios: exactly the deduplicated account scope the view valuation covers, so the total and the return always speak about the same accounts. Money crossing the view boundary counts as an external flow (ADR-0019); money moving between two in-scope accounts nets out. ?period= (ytd|1y|3y|5y|max, default max), ?year=YYYY, ?from=/?to= (custom range) and ?series=true behave like the portfolio performance endpoint; the shape mirrors it with view_id in place of portfolio_id, and all financial values are Decimal strings. Unknown and malformed view ids return 404; a bad period 422.
GET /api/v1/views/:view_id/performance/benchmark returns the view’s benchmark comparison across all portfolios (ADR-0046 §3): the same deduplicated account scope the view valuation and the view performance cover, so the view’s total, its return and its benchmark speak about the same accounts. benchmark= is required and period, year, from/to and series=true behave like the portfolio benchmark read; the shape mirrors it with view_id in place of portfolio_id. Unknown and malformed view ids return 404; a bad period or benchmark 422.
GET /api/v1/views/:view_id/performance/contribution returns the view’s contribution analysis across all portfolios (FR-41, ADR-0051 §6): the same deduplicated account scope the view performance covers, in EUR, so totals.result is that read’s money result and a position held in several portfolios is one row. period, year and from/to behave like the portfolio contribution read; the shape is its shape with portfolio_id: null, view_id and the view echoed. Unknown and malformed view ids return 404; a bad period 422.
GET /api/v1/performance, GET /api/v1/performance/benchmark and GET /api/v1/performance/contribution are the three reads above with no view (#1056): every account of every portfolio, each counted once, the scope Wealth calls Everything, readable before any view exists. Each takes its view read’s parameters (benchmark= stays required on the comparison) and answers its view read’s shape with view_id: null (and portfolio_id: null on the contribution) and no view echo; a bad period is a 422, a missing or refused benchmark a 422 on benchmark. None takes a scope: view= and portfolio_id= are ignored, as on GET /api/v1/valuation. They answer in EUR, the hub, as the view reads and GET /api/v1/valuation do. Wealth computes its Everything figures in the first portfolio’s base currency, so the two differ when that is not EUR, and each payload says so: computation_basis.input_series closes on the scope (every account in every portfolio, no view) and the currency. A view with include_all and nothing excluded reads the same figures. MCP: portfolixir.views.performance, portfolixir.views.benchmark and portfolixir.views.contribution without an id.
GET /api/v1/views/:view_id/category-results?classification_id=<id> returns the per-category result (ADR-0041) of the positions matching the view across all portfolios, each account counted once (#901). The shape is the portfolio read’s with scope: "view", portfolio_id: null and the view echoed. Its figures are in EUR: a member’s invested amount is the settlement leg actually paid (ADR-0033), so a member held in a portfolio whose base currency is not EUR has no EUR cost to add and is excluded with missing_base_cost, never summed across currencies. Unknown and malformed view ids return 404, a missing classification_id 422, an unknown one 404. MCP: portfolixir.portfolios.category_results with view and no portfolio_id.
GET /api/v1/category-results?classification_id=<id> returns the per-category result of every portfolio, with no view (#1091): the roll-up the classification page shows, in the portfolio read’s shape with scope: "all", portfolio_id: null, view_id: null, base_currency: "EUR" and no view echo. The view read’s EUR rule holds: a member held in a portfolio whose base currency is not EUR is excluded with missing_base_cost, and excluded_members names it with its cost in the currency it was paid in; basis_note closes on the scope. It takes no scope: view= and portfolio_id= are ignored, as on GET /api/v1/valuation. A missing classification_id is a 422, an unknown one a 404. MCP: portfolixir.portfolios.category_results with neither portfolio_id nor view.
PUT /api/v1/securities_accounts/:id/buckets replaces a depot’s default bucket set (the buckets each position inherits unless overridden). Body: {"bucket_ids": [..]}. At most one of the ids may be a scope-dimension bucket; a violating set returns 422 without writing anything.
PUT /api/v1/cash_accounts/:id/buckets replaces a cash account’s bucket set. Body: {"bucket_ids": [..]}. The same at-most-one-scope-bucket rule applies.
PUT /api/v1/securities_accounts/:id/positions/:security_id/buckets sets the per-position override for one security in one depot. An empty bucket_ids records the explicit-empty state (deliberately no buckets), distinct from inheriting the depot default; the override always wins over the depot default. The response reports the resolved override (inherit, explicit_empty or explicit) and the effective_bucket_ids.
DELETE /api/v1/securities_accounts/:id/positions/:security_id/buckets clears the override, returning the position to inherit the depot default.

The four assignment writes above hold the depot or cash account while they replace its set, so two writes to one account take turns: the one that commits last is the set that stays, never a mix of both. An account deleted while the write waits answers 404 and writes nothing. The two position override writes also hold the security, after the depot, and a security deleted while they wait answers 404 the same way (#919).

The analytics endpoints accept an optional view query param (a view id) to scope the result to the holdings matching that view:

GET /api/v1/portfolios/:portfolio_id/valuation?view=<id>
GET /api/v1/portfolios/:portfolio_id/allocation?classification_id=<id>&view=<id>
GET /api/v1/portfolios/:portfolio_id/performance?view=<id>
GET /api/v1/portfolios/:portfolio_id/performance/contribution?view=<id>
GET /api/v1/portfolios/:portfolio_id/risk?view=<id>
GET /api/v1/portfolios/:portfolio_id/category-results?classification_id=<id>&view=<id>

When a view is supplied, the response echoes the active view as view: {id, name} (FR-13); the unscoped/default call is unchanged and carries no view field. A malformed view id returns 422; an unknown view id returns 404. The same view scope (and the same 422/404 contract) applies to the target endpoints — GET/PUT /api/v1/portfolios/:portfolio_id/targets, DELETE /api/v1/portfolios/:portfolio_id/targets/:category_id and the cash-target endpoints GET/PUT /api/v1/portfolios/:portfolio_id/cash_target — where a view selects the target plan (omitted = the Gesamt plan). The holdings endpoint (GET /api/v1/portfolios/:portfolio_id/holdings) is not view-scoped: it returns the raw per-(depot, security) rows in each security’s own currency, so a client can apply the buckets/views model itself using each row’s securities_account_id and security_id.

Settings

A minimal keyed preference store backs the user-facing defaults (ADR-0024). Today it carries one preference: the default view the Wealth page and dashboard open on when no explicit view was chosen in the UI. No financial decimals are involved.

GET /api/v1/settings/default_view returns the current default: {"data": {"view_id": null, "view": null}} when unset (the built-in Everything scope), otherwise the id plus a view: {id, name} echo.
PUT /api/v1/settings/default_view sets it. Body: {"view_id": <id>} with a live view id, or {"view_id": null} to clear back to Everything. An unknown view id returns 404 (nothing is written); a malformed view_id returns 422. The response mirrors the GET shape.

Imports

Portfolio Performance imports (CSV/JSON v1) run through the Imports view only: there is no import endpoint under /api/v1 and no MCP tool for it, by design — the preview-then-apply step with its mapping decisions is an operator action (ADR-0029). What the API and MCP consumer needs to know is the re-import preservation guarantee, because everything an agent writes through this API lives next to the imported history:

Re-applying the same export is a content-hash no-op. Every transaction row that already exists is skipped as a duplicate; no security is created twice; the response of the apply reports the skipped count. The hash is injective (two different rows never share one) and every hash stored before it became so is still found. A tax refund split off a row is hashed with that row and checked by its own hashes and economic key, so two equal refunds of two different sales both book, a refund already imported is found under either formula, and a refund added to a row already imported books; a refund whose row is not imported is skipped with it.
A rename is safe for the next import (ADR-0050 §3, §4). The hash is checked before anything resolves, and a cash account or depot is created only with its first new booking, so a rename over PATCH /api/v1/cash_accounts/:id or PATCH /api/v1/securities_accounts/:id (portfolixir.cash_accounts.update, portfolixir.securities_accounts.update, whose descriptions say so) leaves no empty account under the old name. The rename keeps the old name in former_names, and the import resolves a file’s account name by the live name first, then by the former names, so a re-export that changed inside Portfolio Performance (other decimals, an edited booking) books onto the renamed account too and nothing twice. What stays outside: an old name another account still carries as its live name books to that account, and a rename older than the accounts’ audit journal left nothing to remember. A prefilled choice the operator changes in the preview to an account of another name is remembered as a former name of that account by default. Where the name is another account’s former name, the import page moves it only after its row said so before the confirm, and the result names the account it left; DELETE /api/v1/cash_accounts/:id/former_names?name= (or the securities_accounts twin) still removes a former name by hand. A transfer whose two sides lead to one account is skipped and listed, never a failed import.
A cash-account merge is safe for the next import (ADR-0050 §2, §7). After POST /api/v1/cash_accounts/:id/merge, re-applying an export already applied creates nothing, byte-identical or drifted: the moved bookings keep their content hashes, every booking the merge deleted has its hash retired, the source’s name resolves to the target as a former name, and a transfer between the two is skipped as internal. A later export’s new rows that name the merged-away account are booked once, on the target. Two limits are stated, not hidden: a new row whose economic key equals an existing booking of the target is taken for that booking (reported with the layer economics), and a row dated on or before a balance anchor the merge restated is booked but absorbed by that anchor — the import lists it as booked behind a restated anchor, with the anchor.
A depot merge is safe for the next import (ADR-0050 §2, §7). After POST /api/v1/securities_accounts/:id/merge, re-applying an export already applied creates nothing, byte-identical or drifted: the moved bookings keep their content hashes, every booking the merge deleted has its hash retired, the source depot’s name resolves to the target as a former name, and a security transfer between the two is skipped as internal. A later export’s new rows that name the merged-away depot are booked once, on the target. A new row whose economic key equals an existing booking of the target is taken for that booking (reported with the layer economics).
A security merge is safe for the next import (ADR-0050 §2, §9). After POST /api/v1/securities/:id/merge, re-applying an export already applied creates nothing, byte-identical or drifted, whichever ISIN it carries and under either identity choice: the moved bookings keep their content hashes, every booking the merge deleted has its hash retired, and every identity of the source — its ISIN (the target’s now, or a former ISIN of the target), its former ISINs, the identity its import recorded — resolves to the target. A later export’s new rows that name the merged-away security by any of them are booked once, on the target. The merge is refused rather than leave an identity unresolved (identity_unresolvable).
What survives a re-import, unchanged, same ids, exact Decimal values: classification assignments; every target plan version with its category and position targets and the cash target; each security’s note and attributes including custom keys; the security research log (/api/v1/securities/:id/notes — the append-only entries and the thesis_state derived from them, ADR-0044); the security events (/api/v1/securities/:id/events — every dated calendar fact with its timing qualifier, its confirmation and its checked_at, ADR-0048 §7); the policy rules (/api/v1/portfolios/:id/policy_rules — every rule and every version with its subject ids, thresholds and period, ADR-0049 §8); security ids and updated_at. Pinned by test/portfolixir/imports/reimport_preservation_test.exs since issue #664 (research log added by #748, security events by #829, policy rules by #864).
A mutated re-import (a rename, a recorded ISIN change resolved through an alias or an explicit mapping) keeps the same guarantee for the matched securities; only the genuinely new bookings land.
Stated where an agent reads it (issue #831). The descriptions of the eight MCP reads the guarantee protects — portfolixir.notes.list, .unreviewed, .uncorroborated, .expiring and portfolixir.events.list, .upcoming, .unconfirmed, .stale — carry the sentence “A Portfolio Performance re-import does not destroy the research log or the security events”, so an agent meets the answer in the tool list it already reads instead of on this page. The mutated path pins the research log as well as the events. The policy-rule reads (portfolixir.policy_rules.list, .get and portfolixir.portfolios.policy_findings) carry the rules’ own sentence, “A Portfolio Performance re-import does not destroy the policy rules”, and the mutated path pins a rule over the re-ISINed security.
Not covered: a booking that changed in the source. An edited transaction hashes differently and is imported as a new row beside the old one; the old booking is removed or corrected through PATCH/DELETE /api/v1/transactions/:id. The guarantee is about what Portfolixir maintains around the history, not about reconciling two versions of the history itself.

A research log, a calendar, a rule, a plan or an assignment therefore never “disappears at the next import”; an agent that observes otherwise has found a defect, not a documented limitation.

Contract Version

The surface says what it is, so a consumer can notice it changed (ADR-0044 §8). A tool description is read once at connect time; this read is how an agent learns that the list or the descriptions moved.

GET /api/v1/contract returns the contract manifest: version (an integer, the newest entry’s), last_changed_at (ISO date), endpoints_total, tools_total, and entries newest first — each with version, date, summary, the endpoints ("VERB /api/v1/path") and tools the change added, parameters (one sentence per parameter added to an existing read) and any removed_endpoints / removed_tools. Optional since=YYYY-MM-DD narrows the entries to those dated strictly after that day and answers changed — the ?since= idea applied to the contract instead of the rows: store last_changed_at, poll with it, and re-read the tool list and descriptions when changed is true. An invalid since is a 422.
The manifest is code-maintained (PortfolixirWeb.Api.V1.Contract) and a meta-test ties the router’s /api/v1 inventory and the MCP companion’s tool and prompt inventories to it in both directions, so a route, tool or MCP prompt added, renamed or removed without a manifest entry fails the build; an entry names a prompt in its summary and parameters. Its first entry records the Sprint 9 additions — the research log, the thesis state, the include_positions / min_drift parameters that reached the view scope and the position level (#740), the historical backfill scope (#737), and this read.

Audit Journal

Every financial write (create, update, delete) is recorded in an append-only audit journal in the same database transaction as the write itself, so any change — including deletions — stays attributable and reversible by inspection. Market-data ingestion (quote and exchange-rate sync) is operational data and is deliberately not journaled. A quote someone writes is not ingestion: the quote upsert and the release of manual quotes are journaled under resource_type=security_quotes, filed under the security’s id, with the rows they replaced or released as the before-image.

GET /api/v1/journal lists journal entries, newest first. Each entry carries actor_type (owner_ui, api_token_rw, api_token_ro, import_session, system_job) and an optional actor_label (for an API token, the name of its PORTFOLIXIR_API_TOKENS entry; null for the unnamed default), the operation (create, update, delete, upsert), the resource_type/resource_id it touched, and the before/after snapshots (Decimal values are strings). Optional filters: resource_type, resource_id, actor_type, operation, limit (default 100, max 1000) and include_scenarios (true to include persisted what-if writes; real writes only by default). The response is self-describing: a meta object echoes the as_of instant, the order (inserted_at:desc,id:desc), the count and the filters applied. SOLL target writes (category and position rows alike) are journaled under resource_type=target; plan-version writes under resource_type=target_plan.
An update’s or a delete’s before is the row as stored when the write took its lock, and an update’s after is the row as stored after it — decimals at their column’s scale. Two writes made from one read therefore chain: the second’s before is the first’s after. A write to a record deleted in the meantime answers 404 and leaves no entry.
A bucket assignment’s entry (depot_bucket_assignment, cash_account_bucket_assignment, position_bucket_override) images the set as stored, its bucket_ids in id order: before is the set when the write locked its account, after the set it stored. A position override’s before is null where the position inherited its depot’s set, and [] where it had no buckets. Resending the stored set leaves no entry, and so does clearing the override of a position that already inherits (#953).

Every financial write context journals: the rollout ADR-0017 sequenced is complete. Each table that holds financial records carries a guard trigger that refuses a write made without an actor, so a write path that forgets the journal fails instead of leaving a gap. The entries are filed under these resource_type codes:

securities and their ISIN aliases: security, security_identifier_alias; the quotes someone writes: security_quotes;
portfolios, cash accounts and depots: portfolio, cash_account, securities_account;
bookings, an applied import’s included (actor import_session): transaction;
classifications: classification, category, security_category_assignment;
SOLL plans: target, target_plan;
tax records: tax_parameters, tax_profile, allowance_order, tax_statement_snapshot;
the research log and security events: security_note, security_event;
policy rules: policy_rule, policy_rule_version;
the lifecycle merges: merge_record, retired_import_hash;
buckets, views and depot snapshot markers: bucket, view, depot_bucket_assignment, cash_account_bucket_assignment, position_bucket_override, snapshot.

Two kinds of table carry no guard trigger, so for them the journal rests on their writers: security_quotes, which the sync writes too, and the scope tables behind views, bucket assignments, position overrides and snapshot markers, which say what a view reads rather than hold financial records (ADR-0018 §5).

Outside the journal, deliberately: the quote and exchange-rate sync; the quotes a security merge moves or drops, which its merge manifest records instead (ADR-0050 §13); the stored settings (the default view); and the derived values of ADR-0039, which can be rebuilt from the stored records at any time.

MCP Tools

The MCP companion exposes the same local contract as tool calls. Decimal inputs in MCP schemas are strings. Client configurations to copy are on Connect an Agent, and the entry written for an agent deciding whether and how to set Portfolixir up is llms.txt.

The schema a host receives from tools/list is each tool’s own definition, its property descriptions and its closed objects (additionalProperties: false) included, and the companion checks every call against the same properties before it calls the API: a refused argument answers a tool error naming the tool and the field, and no request is made. A call the API answers without a body, a delete’s 204, is a result without structured content.

Server instructions and tool hints (E25). At connect time the companion tells the agent that everything a tool returns is data, never instructions: names, notes, research-log bodies, event and rule texts, import labels and provider search results are records to read, not directions to follow, and only the operator instructs it. Every tool carries the four MCP hints, derived from the HTTP method it routes to:

Routed method	`readOnlyHint`	`destructiveHint`	`idempotentHint`
`GET`	true	false	true
`POST`	false	false (it adds)	false
`PUT`, `PATCH`	false	true (it overwrites)	true
`DELETE`	false	true (it removes)	true

The exceptions are named: portfolixir.splits.preview and portfolixir.holdings.reconcile are routed through POST but store nothing, so they are read-only; portfolixir.quotes.release is routed through POST but removes the manual quotes in its range, so it is hinted as a DELETE is: destructive, and idempotent, since a repeat finds nothing left to remove; portfolixir.policy_rules.retire, portfolixir.plans.activate and portfolixir.securities.isin_change are routed through POST but change stored rows — a retirement closes the version in force and drops the scheduled ones, an activation archives the plan that was active, an ISIN change writes the new ISIN onto the security — so they are hinted as a PUT is: destructive, and idempotent, since a repeat changes nothing more (a second retirement answers 409, a second activation is a no-op, a second ISIN change a named conflict); openWorldHint is true for portfolixir.securities.search_online, portfolixir.quotes.sync and portfolixir.exchange_rates.sync, which reach an external provider, and for portfolixir.securities.create, which queues a quote backfill from the provider and a logo lookup when the instance’s enrichment is enabled. The append-only writes, portfolixir.notes.append and the policy-rule versions, are non-destructive, and their descriptions say that what they add is permanent.

Auto-approvable reads. A host may run every tool with readOnlyHint: true without asking: none of them changes the instance. portfolixir.securities.search_online is among them but sends its query to the configured provider, so keep it behind a prompt if that matters to you. A host that asks before every other tool, and at the least before each one with destructiveHint: true, keeps every write in view.

Read-only mode. Set PORTFOLIXIR_MCP_READ_ONLY=true to run the companion read-only: tools/list then lists only the tools with readOnlyHint: true, and a call to any other tool, listed or not, is refused as a tool error naming the switch before any request is made. It is off by default, and a value other than true, false, 1, 0 or empty stops the companion with the variable named. The switch narrows the companion, not the token: PORTFOLIXIR_API_TOKEN keeps its full authority over the API.

Tool profiles. PORTFOLIXIR_MCP_PROFILE takes read, book or full (the default), in any case. read is the read-only mode above. full lists and calls every tool. book lists the reads, every create and the replace-shaped writes, and leaves out the admin set, an explicit list in the companion (mcp-server/src/profiles.ts) drawn by one line, as implemented: removal-shaped tools are admin, and replace-shaped writes stay in book. Every removal is admin (every delete, the former-name and ISIN-alias removals, a classification’s unassignment, a position’s override cleared, the release of manual quotes), even where a later write could put an equal row back, and so are the three merges, the ISIN change and a rule’s retirement. A replace-shaped write (an update, an upsert, a bucket set, a plan’s activation) stays in book, because the same write sent the former value undoes it; a bucket set sent narrower, or a position’s override set to [], stays too, while clearing the override is admin. Two kept writes leave a residue their inverse does not clear: a rename back restores the live name but keeps the in-between name as a former name, which no new account may take and a later import naming it books onto that account, until portfolixir.cash_accounts.remove_former_name (or the depot twin), an admin tool, clears it; and an upsert over a date that held provider data leaves that date manual, which only portfolixir.quotes.release, an admin tool, hands back. The writes book keeps are a second list beside the admin set, each with its reason, and a companion test fails any tool with destructiveHint: true that sits in neither. Under book a call to an admin tool, listed or not, is refused as a tool error naming the profile and PORTFOLIXIR_MCP_PROFILE=book before any request is made, and the server instructions name the profile in one clause. PORTFOLIXIR_MCP_READ_ONLY=true is read: alone or beside PORTFOLIXIR_MCP_PROFILE=read it agrees, and beside PORTFOLIXIR_MCP_PROFILE=book or full it stops the companion naming both variables; PORTFOLIXIR_MCP_READ_ONLY=false, the shipped default, only means the switch is off and never conflicts. Any other value stops the companion with the variable named. A profile narrows the companion, not the API token. It keeps an unattended agent run from deleting or merging through the companion; an agent that can reach the API with the token can still call every route.

Scope twins. Valuation, performance, the benchmark comparison and the contribution analysis exist at two scopes, and each tool of a pair names the other in its description with the difference (Sprint 17, D-6): portfolixir.portfolios.* answers one portfolio record in its base currency, its view narrowing within that portfolio; portfolixir.views.* answers a view across every portfolio, each account counted once, in EUR. The total across every portfolio needs no view: portfolixir.views.valuation without an id reads it (GET /api/v1/valuation, #1007), always in EUR over every account — the dashboard’s total when the first portfolio’s base currency is EUR and no default view is set — so a sum of portfolio valuations is never the route to it. The view performance, benchmark and contribution tools need no view either: without an id each reads every account in EUR (GET /api/v1/performance, /performance/benchmark, /performance/contribution, #1056), so a return or a contribution of everything is one read, never a sum of portfolios — returns of several portfolios never add up. Wealth computes its Everything figures in the first portfolio’s base currency, so they differ from these when that is not EUR, as each payload’s computation_basis says.

Prompts. The companion offers two MCP prompts (prompts/list, prompts/get), the same under every profile, each carrying the no-advice framing in its own text: the system prepares decisions and the operator executes them, and nothing places, proposes or sizes a trade.

first_setup checks the instance (portfolixir.contract.get) and names the active profile, reads what exists, proposes cash accounts, depots, buckets and views (none for the total across everything, which needs no view), explains how data gets in, and writes nothing without the operator’s confirmation.
import_converter (optional argument export_file) guides the user’s agent to write and run, on the operator’s machine, a converter from a bank or broker export to a Portfolio Performance CSV v1 file the operator drops on the Imports page, which previews it and applies it idempotently. It states the format exactly: the header, ;, YYYY-MM-DD dates, German numbers, the German type labels, Betrag as each row’s cash effect, Konto and Gegenkonto per type, the EUR-only rule, and the JSON v1 variant for other currencies and for ISINs, with one synthetic example of each that a test takes through the real Imports page. It names the rows the preview refuses: a transfer without both sides, a trade without its cash account, an ISIN without a valid check digit, and, in JSON v1, a currency other than those the security dialog offers. It binds the agent: no broker sync, no network call and no model call, synthetic examples only, and booking the converted rows one by one through portfolixir.transactions.create is not a substitute, because it skips the preview and the content-hash idempotency.

The prompts exist over MCP only: a prompt is an instruction to the user’s agent, and the API has nothing to serve it to.

Invisible characters. Every write refuses the characters an operator cannot see (see “Text” above), but a row stored before that rule may still carry them. The companion is where they are made visible: every string an API answer carries, a value or a key at any depth, reaches the agent with each such character spelled [U+XXXX] ([U+200B] for a zero-width space) — the same spelling Portfolixir’s screens show the operator for that row, and the server instructions say so. The JSON API itself answers stored text as it is stored. A text the agent writes back carries the escapes as the visible letters they are.

A record named in a sentence (#965). A sentence the app writes names another record by its kind and id, never by its stored name, so a name that reads like an instruction never sits inside the app’s own words: an ISIN-change or alias refusal names security #12, and a former-name refusal of a cash-account or depot write names cash account #5 or securities account #5 (errors.former_names: “include the name of cash account #5 in this portfolio”), and a security merge’s guard detail names its rules, depots, buckets and portfolios by their ids (policy rule(s): #7 (in_force), In depot #3, in portfolio #1) and an identity’s name as “its recorded name”, and a split booked again names the existing event’s portfolio by its id (for portfolio #1). A delete refused because a policy rule reads the object (409) names the rules the same way, and a cash-account or depot merge’s guard detail names its buckets and a position by their ids (the buckets #3, #7, security #12 sits in the bucket #9). The record’s name is a field of the record, read by its id (a depot’s from GET /api/v1/securities_accounts/:id, a bucket’s from GET /api/v1/buckets/:id, a rule’s from GET /api/v1/policy_rules/:id, a security’s from GET /api/v1/securities/:id, a portfolio’s from GET /api/v1/portfolios). A refusal’s errors carry a name beside the detail in two places only: errors.policy_rules[].name, with each rule’s id and status, and errors.unresolvable[].ref.name, the identity’s recorded name; a depot, a portfolio and a bucket travel there by their ids alone. Portfolixir’s screens keep naming it by its name.

A write that times out. Every API call carries a 30-second deadline. A read that misses it — a GET, or one of the tools routed through POST that change nothing (readOnlyHint: true) — changes nothing and answers ApiReadTimeoutError, so it can be retried; any other call that misses it answers ApiOutcomeUnknownError: the companion stopped waiting, but the server may still have committed the write, so re-read what it would have changed before retrying. A blind retry of a write that adds a record can store a duplicate, and every such tool (each write that is not idempotent) says so in its description; the server instructions say it once for every write.

A write whose connection fails in a way that does not show the request never left (a reset, a socket closed while the answer arrives, a TLS failure, a failure with no code) answers ApiOutcomeUnknownError the same way, with the failure’s code in its message: the request may have been sent, and the server may have committed it. A failure that shows the request never reached the API (the connection refused, the name not resolved, the host or network unreachable, the address family unsupported or no local address available, the connect itself timing out, a base URL that does not parse as a URL) stays a plain error and is safe to retry, as is any failure of a read. For a name that resolves to several addresses, the request counts as never sent only when the connect failed that way on every one of them; otherwise the message names each address’s code.

A gateway error, or an answer that is not JSON. Behind a reverse proxy, a write answered 502, 504, or Cloudflare’s 520 or 524 answers ApiOutcomeUnknownError: its message says the gateway answered that status instead of the server, and the server may still have committed the write, so re-read what it would have changed before retrying. The exception is a 502 in the API’s own JSON error envelope, a body of exactly one key, errors, holding a non-empty object: the API answers 502 that way when the rate provider fails during portfolixir.exchange_rates.sync, with nothing stored, so that is the server’s answer, nothing about the write is unknown, and it stays the plain error Portfolixir API request failed: 502 {…} with the API’s detail. An empty errors object, or one beside other keys, is a gateway’s. The API answers none of the other three statuses, so they are a gateway’s whatever their body. A read answered any of the four changes nothing; it stays a plain error that names the status, or says the answer had no body, and says a retry is safe. A 503 is not read as an unknown outcome: a proxy that answers 503 usually did not forward the request, but some proxies (Envoy, Istio) answer 503 after forwarding it, so re-read before retrying a write that got one. An answer whose body is not JSON (an HTML error page, a proxy’s 413) is never passed on as a parse failure: its error names the status and quotes at most 120 characters of the body as the message carries it, JSON escapes counted, JSON’s whitespace collapsed, and invisible characters and any other blank character (a no-break space, a form feed) spelled out, with the body’s length in bytes when it was cut. The companion’s API token, and any Bearer value, reads [redacted] in that quote and in a quoted JSON error, so a proxy page that echoes the request’s headers cannot hand the token on. A write answered 2xx with such a body answers ApiOutcomeUnknownError too: the API may have committed it, and its answer cannot be read.

portfolixir.contract.get — the contract-version read (ADR-0044 §8): what the surface offers and when it last changed, pollable with since=.
portfolixir.securities.list
portfolixir.securities.get — one security’s full record including its identifier_aliases (recorded former ISINs) and its derived thesis_state (ADR-0044) and, for a bond, its bond reading with each metric’s computation_basis and the two-scales finding (ADR-0052); a merged-away security answers 404 with errors.merged_into, and the description says so (ADR-0050 §12).
portfolixir.securities.create — takes a bond’s master data (#330, ADR-0052).
portfolixir.securities.update — its description and its currency_code property state the currency freeze, the property citing ADR-0050 §11; it takes a bond’s master data, null clearing a field, and is_retired: true takes a sold-out or delisted security out of the stale_quote, missing_quote and missing_logo sets and false restores it. It is also the remedy portfolixir.securities.delete names when research notes or policy-rule versions reference a security. The tool is in the book profile.
portfolixir.securities.delete — names portfolixir.securities.update with is_retired for the retire remedy.
portfolixir.securities.isin_change — records a corporate-action ISIN change so imports keep matching via the former ISIN (ADR-0029).
portfolixir.securities.delete_isin_alias — journaled delete of one recorded former-ISIN alias.
portfolixir.securities.merge_preview — the security merge preview, a read (ADR-0050 §9, §10): the positions per depot for both outcomes of the duplicate question, the quotes with the manual collisions, the configuration and events, the identifiers after each identity choice, and the plan_digest.
portfolixir.securities.merge — the security merge under an approved digest; hinted destructive and idempotent (a retry answers the original record). Its description says that identity_choice is required when both carry an ISIN and never preselected, what each value does, that the quotes fill the target’s gaps with the target’s winning a collision, that the configuration and events move, and what the merge does to the next import: every identity of the source resolves to the target, a later import naming it books there, a re-import of an applied export creates nothing, and a merge that would leave an identity unresolved is refused.
portfolixir.securities.search_online
portfolixir.events.list — one security’s calendar (ADR-0048); the description states that an event books nothing and is never converted into a transaction.
portfolixir.events.create — records a dated fact; the description spells out that timing says how well the date is known.
portfolixir.events.update — corrects or confirms one in place, because an event is mutable by design.
portfolixir.events.delete — removes a duplicate, journaled.
portfolixir.events.upcoming — what is due within N days across the whole catalog; held_only narrows and is never the default.
portfolixir.events.unconfirmed — dates that passed with nobody confirming them.
portfolixir.events.stale — dates nobody has re-read in N days.
portfolixir.securities.metrics — one security’s derived price metrics (ADR-0047) over its own split-adjusted close series: moving averages, volatility, maximum drawdown, momentum and the distance to the 52-week extremes, each with its window and observation count. Reports only; the description says so.
portfolixir.notes.list — a security’s research log newest first with the derived thesis state; the description states that entries never vanish (ADR-0044).
portfolixir.notes.append — the only write the log admits; a retraction with supersedes_id is how a finding is withdrawn.
portfolixir.notes.unreviewed — held positions with no entry for N days.
portfolixir.notes.uncorroborated — entries whose source quality is not primary.
portfolixir.notes.expiring — dated blocks expiring within N days.
portfolixir.quotes.sync
portfolixir.quotes.list
portfolixir.quotes.upsert — every row stored as manual; its schema offers source: manual only, and the answer names the replaced dates.
portfolixir.quotes.manual — a security’s manual quotes over the whole history: count, first and last date, the stretches, the count of a range, and whether the sync can refill a released date; a read.
portfolixir.quotes.release — the journaled release of a range’s manual quotes back to provider data; the operator’s control is Release… on the security’s Quotes tab.
portfolixir.portfolios.list — deprecated (ADR-0024): steers to buckets/views in its description.
portfolixir.portfolios.create — deprecated (ADR-0024): compatibility only; prefer portfolixir.buckets.create / portfolixir.views.create.
portfolixir.cash_accounts.list
portfolixir.cash_accounts.create
portfolixir.cash_accounts.update — its description and its currency_code property state the currency freeze (ADR-0050 §11).
portfolixir.cash_accounts.delete
portfolixir.cash_accounts.set_balance
portfolixir.cash_accounts.remove_former_name — removes one former name (ADR-0050 §4); its description says what that costs: an import that still names it then creates a new account.
portfolixir.cash_accounts.merge_preview — the merge preview, a read (ADR-0050 §7, §10): both outcomes of the duplicate question and the plan_digest.
portfolixir.cash_accounts.merge — the merge under an approved digest; hinted destructive and idempotent (a retry answers the original record). Its description says what the merge does to the next import: the source’s names become former names of the target, a later import naming them books there — except a name another account still carries, which is not kept — and a re-import of an applied export creates nothing.

portfolixir.securities_accounts.create
portfolixir.securities_accounts.update
portfolixir.securities_accounts.delete
portfolixir.securities_accounts.remove_former_name — the same for a depot.
portfolixir.securities_accounts.merge_preview — the depot merge preview, a read (ADR-0050 §7, §10): every affected position before and after for both outcomes of the duplicate question, the bucket plan, positions_basis and the plan_digest.
portfolixir.securities_accounts.merge — the depot merge under an approved digest; hinted destructive and idempotent (a retry answers the original record). Its description says that bookings keep their cash account, that every position keeps its view membership, and what the merge does to the next import: the source’s names become former names of the target, a later import naming them books there — except a name another depot still carries, which is not kept — and a re-import of an applied export creates nothing.
portfolixir.transactions.list
portfolixir.transactions.create
portfolixir.transactions.update
portfolixir.transactions.delete — one row; on a split it names portfolixir.splits.delete
portfolixir.splits.preview
portfolixir.splits.create
portfolixir.splits.delete — the whole split from any of its rows, every portfolio’s row in one journaled step (#912); an admin tool, so the book profile leaves it out
portfolixir.holdings.list
portfolixir.cashflow.realized_gains — the #724 roll-up with its stated FX basis and the excluded-and-named gap treatment, and each trade’s annualized return (#984)
portfolixir.cashflow.external_flows — the #725 roll-up with the stated invested-capital difference
portfolixir.cashflow.costs — the #726 roll-up with the stated legs-not-gross series rule
portfolixir.holdings.by_security
portfolixir.holdings.negative
portfolixir.holdings.reconcile — read-only compare of a pasted external position list against the ledger; its description steers the agent toward booking the missing transaction of the correct kind instead of balance snapshots or unpriced deliveries.
portfolixir.portfolios.valuation — scope twin of portfolixir.views.valuation (see “Scope twins” above). Both pass unvalued_cash_count through, with or without include_positions (#1081).
portfolixir.exchange_rates.list
portfolixir.exchange_rates.sync — scope=latest (daily feed) or scope=history (the one-shot historical backfill, issue #737).
portfolixir.classifications.list
portfolixir.classifications.create
portfolixir.classifications.categories.create
portfolixir.classifications.update
portfolixir.classifications.delete — one call removes the tree with every category, every security’s assignment in it, every target weight on its categories and every target plan of it; the description names each, and that each of those rows is journaled as its own delete before the classification’s (E25).
portfolixir.classifications.categories.update
portfolixir.classifications.categories.delete — one call removes the category with its sub-categories at every depth, the assignments to any of them and the target weights on any of them; the journal keeps each as its own delete, the category itself last.

portfolixir.portfolios.allocation
portfolixir.portfolios.category_results — one portfolio, which view narrows, view alone for the view across every portfolio (#901), or neither for every portfolio in EUR (#1091).
portfolixir.portfolios.risk
portfolixir.policy_rules.list — the stored rules with the version in force on as_of (ADR-0049); the description tells the agent to read them here instead of restating them, calls each a stored rule whoever wrote it, and points to the audit journal for its author.
portfolixir.policy_rules.get — one rule with its whole version history.
portfolixir.policy_rules.create — stores a rule with its first version; the description carries the measure matrix and the scales, and states that a version is permanent once in force: the rule can then only be retired.
portfolixir.policy_rules.add_version — the edit: a new version, never an overwrite, and permanent once in force.
portfolixir.policy_rules.rename — the name only; the description states that a rename creates no version and the versions do not change.
portfolixir.policy_rules.retire — ends the version in force; everything stays readable.
portfolixir.policy_rules.delete — only for a rule nobody was ever measured against.
portfolixir.portfolios.policy_findings — did anything cross a line? The rules in force today evaluated into findings; status=breached is the alarm list, and the description says undetermined is never a pass.

portfolixir.portfolios.performance — scope twin of portfolixir.views.performance.
portfolixir.portfolios.benchmark — scope twin of portfolixir.views.benchmark.
portfolixir.portfolios.contribution — scope twin of portfolixir.views.contribution; which position made how much of a period’s money result (FR-41).
portfolixir.journal.list
portfolixir.merges.list — the merge records, newest first, each with what went into what, who did it, when, and the manifest summarized (ADR-0050 §12), the removed bookings also per reason; a read — the operator’s list is Merges on Accounts & depots.

portfolixir.views.delete — one call removes the view with its bucket sets, every target plan scoped to it and every depot snapshot taken in its scope; each is journaled as its own delete before the view’s.
portfolixir.views.set_buckets
portfolixir.views.valuation — scope twin of portfolixir.portfolios.valuation; without an id, the total of every account (#1007).
portfolixir.views.performance — scope twin of portfolixir.portfolios.performance.

The portfolixir.portfolios.valuation, portfolixir.portfolios.allocation, portfolixir.portfolios.performance, portfolixir.portfolios.contribution, portfolixir.portfolios.risk and portfolixir.portfolios.category_results tools accept an optional view (a view id) that scopes the result to the holdings matching that bucket view; the response then echoes the active view. portfolixir.portfolios.category_results also takes view without portfolio_id: the view across every portfolio, in EUR (#901); with neither it reads every portfolio, in EUR (#1091). portfolixir.views.valuation values a view across all portfolios in one call (each matching account counted once, EUR totals, overlap badge data), and without an id the total of every account (#1007) — use it instead of summing per-portfolio valuations client-side. portfolixir.views.performance computes the matching cross-portfolio TTWROR/IRR for the same account scope, with boundary-crossing money treated as an external flow (ADR-0019), and without an id the return of every account, in EUR (#1056). portfolixir.settings.get_default_view / portfolixir.settings.set_default_view read and set the default-view preference (ADR-0024): pass a view_id to pin a view, or null/omit it to clear back to the built-in Everything scope.

portfolixir.portfolios.benchmark and portfolixir.views.benchmark are the twins of the two benchmark reads (ADR-0046): benchmark is rate:<decimal> or security:<id>, the period, view and series parameters are the performance tools’, and the response carries both comparisons, the covered window, the excluded flows and the computation basis with the frictionless assumption stated. The view tool without an id compares every account, in EUR (#1056). A refused benchmark comes back as the API’s 422 body, merged_into included for a merged-away security whose survivor is a benchmark (#959).

portfolixir.portfolios.contribution and portfolixir.views.contribution are the twins of the two contribution reads (FR-41, ADR-0051): the period and view parameters are the performance tools’ (there is no series), and the response carries each position’s contribution, the three remainder lines, the totals — positions plus remainder is result, the performance read’s money result — and the computation basis with its assumptions stated. Both are reads, so every profile lists them. The view tool without an id reads every account, in EUR (#1056).

Since ADR-0020 the target tools (portfolixir.targets.list, portfolixir.targets.set, portfolixir.targets.delete) and the cash-target tools (portfolixir.portfolios.cash_target to read, portfolixir.portfolios.set_cash_target to set or clear) also accept an optional view (a view id) that selects the target plan; omitting it addresses the portfolio-wide Gesamt plan. The cash target moved off the portfolio object onto the plan, but portfolixir.portfolios.set_cash_target without a view still steers the Gesamt cash target, so it keeps the same effect as the legacy portfolio cash_target_weight field. All cash targets and target weights are exposed and accepted as Decimal strings.

Since ADR-0030 (#481) the same tools carry position-level SOLL: a portfolixir.targets.set entry that adds a security_id sets a weight on that individual position under its category, portfolixir.targets.list_positions reads the position rows plus each category’s effective roll-up (explicit, position sum, effective steering weight, and a conflict flag surfacing an explicit/position mismatch — plus per-row stale and per-category has_stale flags marking rows whose security no longer sits under the stored category), and portfolixir.targets.delete_position removes one position target. Category-only calls are unchanged.

Since ADR-0027 the plan tools (portfolixir.plans.list, portfolixir.plans.duplicate, portfolixir.plans.activate, portfolixir.plans.rename, portfolixir.plans.delete) manage named plan versions: duplicate the active plan into a draft, edit the draft by passing its id as plan_id to portfolixir.targets.set, portfolixir.targets.delete and portfolixir.targets.delete_position (issue #1133; without it they write the view’s active plan, and an archived plan is refused), or in the SOLL editor, then activate it. The snapshot tools (portfolixir.snapshots.list, portfolixir.snapshots.create, portfolixir.snapshots.delete, portfolixir.snapshots.comparison) freeze a depot state as a marker and read the counterfactual comparison; every financial value in the comparison is a Decimal string and the response labels its basis (gross, price-return only).
