  title: Ledger v3 API
  description: |
    API for Ledger v3, a distributed accounting ledger with Raft consensus.
    Signed and ordinary transaction mutations use application/json, including
    MIME parameters. Either Formance-Signing-Key-Id or Formance-Signature header,
    even if empty, selects the signed wrapper containing request and payload on
    the five supporting operations. Both headers are then required exactly once
    and nonempty. With neither header present, the ordinary unsigned REST body applies.
    Signing headers with a non-JSON or missing content type, or on other /v3
    operations, reject with HTTP 415 and an ErrorResponse JSON body.

        StatefulSet `OrderedReady` ordering: it is intentionally permissive so
        peer pods can be brought up during a cold start where quorum cannot
        form until they exist. Use `/clusterz` for the stricter
        cluster-availability signal.

        healthy and a leader elected). Disk and clock skew gate writes (see
        admission), not cluster readiness. Returns 503 otherwise. Use this
        for external monitoring or any client that needs to wait until the node
        can actually serve cluster-dependent traffic. Kubernetes readiness
        probes should target `/readyz` instead — this endpoint MUST NOT gate
        StatefulSet ordering, otherwise the cluster cannot recover from a
        full-kill cold start.

        Creates a new ledger with the specified name. Storage is configured at the server level.
        Each ledger has its own Raft group for data consistency. Requires `ledger:write` scope.

        The ledger name `_` is reserved: all system / non-ledger routes live
        under the `/v3/_/…` segment (e.g. `/v3/_/audit-entries`), so a ledger
        named `_` would be unreachable over REST. Creating it is rejected with a
        validation error. The exact name `_system` is also reserved for system
        events and rejected. Other underscore-prefixed names remain valid.

        Returns aggregate usage statistics (transaction, volume, reference, posting, log, revert
        and Numscript-execution counts, plus ephemeral-evicted and transient-used volume tallies)
        for a ledger. Requires `ledger:read` scope.
        On live reads, `transactionCount` and `logCount` are FSM-backed. The seven
        usage-derived counters (`postingCount`, `revertCount`, `numscriptExecutionCount`,
        `referenceCount`, `ephemeralEvictedCount`, `transientUsedCount`, `volumeCount`)
        are materialised asynchronously in the serving replica's usagestore and may lag
        committed state even after the request's ReadIndex barrier.
        Note: for checkpoint-scoped (historical) reads, only `transactionCount` and `logCount` are
        checkpoint-consistent; the usage-derived counters (`postingCount`, `revertCount`,
        `numscriptExecutionCount`, `referenceCount`, `ephemeralEvictedCount`, `transientUsedCount`,
        `volumeCount`) are sourced from the live usagestore projection, which is not checkpoint-aware,
        and are returned as `0` at a checkpoint rather than a live value — treat `0` on a checkpoint
        read as "not available at this checkpoint".

        checkpoint reads. Filters containing indexed audit conditions wait for
        the audit projection to certify the request's fixed main-store horizon;
        matching entries are loaded from that same main snapshot. Unfiltered
        reads and sequence-only bounds scan the audit zone directly without
        waiting for the audit projection.

        Requires `ledger:ReadAudit` scope.

            A filter, decoded by the same shared dual-format decoder every list
            endpoint uses (see the `ListFilter` parameter), restricted to bare
            audit fields (`outcome`, `ledger`, `seq`, `proposal_id`,
            `timestamp`, `log_seq`, `caller_subject`, `order_type`,
            `idempotency_key`). These are
            written without any prefix and are resolved against the audit query
            target (EN-1549 — this replaced the old `audit[...]` namespaced
            syntax; it is a breaking change with no backward compatibility):
              - `outcome == failure`
              - `ledger == main`
              - `order_type in (create_transaction, revert_transaction)`
              - `seq between 1000 and 2000`
              - `timestamp >= "2023-11-14T22:13:20Z"`
              - `idempotency_key == "retry-123"`
              - `idempotency_key ^= "import-2026-"`
            Supported fields: `seq`, `proposal_id`, `log_seq` (numeric);
            `timestamp` (RFC3339 or unix microseconds); `outcome`
            (success|failure), `ledger`, `caller_subject`, `order_type`,
            `idempotency_key` (string; `idempotency_key` also supports prefix
            matching with `^=`; a reused key returns every historical audit
            entry; bare alphanumeric values are accepted unquoted, while values
            containing `-`, `:`, spaces, or other non-identifier characters
            must be single- or double-quoted; keys containing both `"` and `'`
            cannot be expressed in the textual DSL: use the structured form for
            exact and `in` lookups (`{"$match":{"idempotency_key":"…"}}`, an
            `$or` of such leaves) and the gRPC API directly
            (`AuditCondition.string_prefix`) for prefix lookups). Bare audit fields are resolved against the audit query
            target: `timestamp` and `ledger` collide with the transaction
            `timestamp` field and the top-level `ledger` condition, so on the
            audit target they resolve to the audit condition (and only there —
            hence audit fields are valid on this endpoint only). The structured
            JSON form uses the same bare field names, resolved against the
            audit target the same way: `{"$match":{"outcome":"failure"}}`,
            `{"$gte":{"seq":1000}}`, `{"$match":{"idempotency_key":"retry-123"}}`.
            Parameters (`{"$param": …}`) are rejected on audit fields, and the
            `idempotency_key ^=` prefix match has no structured form (the JSON
            DSL has no prefix operator).

        Signed requests use `application/json` (including MIME parameters) with
        `request` and standard-base64 `payload`. Either signing header, even if
        empty, selects this wrapper; with neither header present, the ordinary REST body applies.
        Runtime headers choose the representation from the documented anyOf.
        The signed protobuf batch must
        equal the route/body/Idempotency-Key-derived batch in full. Supply exactly
        one nonempty Formance-Signing-Key-Id and Formance-Signature header; the
        latter is a standard-base64 Ed25519 signature of 64 decoded bytes. Missing,
        empty or repeated signing headers, invalid base64 and wrong signature
        length return 400. Signing headers with a non-JSON or missing content type return 415.
        Signature enforcement
        returns 401 `UNAUTHENTICATED` when required but absent and 403
        `PERMISSION_DENIED` for invalid, unknown/revoked-key or mismatched
        signatures. Malformed signed envelopes return 400. The complete
        wrapper counts toward the 4 MiB body limit. JWT scopes still apply.

      summary: List transactions for a ledger
      description: |
        Lists transactions for a specific ledger. The default order is
        newest-first (descending transaction id); pass `reverse=true` to
        get oldest-first (ascending). Supports cursor pagination (`pageSize`,
        `cursor`), an optional date range (`startDate`/`endDate`),
        and the generic `filter` parameter (e.g. reference selection via
        `filter={"$match":{"reference":"..."}}`, URL-encoded). Requires
        `ledger:ReadTransaction` scope.

        Exact address filters search retained transaction history for any,
        source and destination roles even when the current account is absent.
        Address prefixes enumerate current accounts. Purging an EPHEMERAL
        volume does not remove exact historical address matches. Previously
        omitted index mappings require an explicit address-index repair.

        This is a live read, linearizable by default. `X-Consistency: stale`
        reads the receiving node's local state, which may lag the leader. Every
        projection used by the filter is automatically aligned. Unlike the
        gRPC API, it does not accept the `checkpointId` option to pin the read
        to a specific historical snapshot — use gRPC for checkpoint-pinned
        reads. (Tracked follow-up, same carve-out as the audit reads.)

        Signed requests use `application/json` (including MIME parameters) with
        `request` and standard-base64 `payload`. Either signing header, even if
        empty, selects this wrapper; with neither header present, the ordinary REST body applies.
        Runtime headers choose the representation from the documented anyOf.
        The signed protobuf batch must
        equal the route/body/Idempotency-Key-derived batch in full. Supply exactly
        one nonempty Formance-Signing-Key-Id and Formance-Signature header; the

        empty or repeated signing headers, invalid base64 and wrong signature
        length return 400. Signing headers with a non-JSON or missing content type return 415.
        Signature enforcement
        returns 401 `UNAUTHENTICATED` when required but absent and 403
        `PERMISSION_DENIED` for invalid, unknown/revoked-key or mismatched

    post:
      summary: Revert a transaction
      description: |
        Reverts a transaction by creating a reverse transaction that undoes its effects. Requires `ledger:write` scope.
        The body is optional; an absent or empty body uses default options. Supplied
        options and metadata are decoded for both known-length and HTTP/1.1 chunked
        requests. Malformed or truncated JSON, extra values, trailing non-whitespace
        and options of the wrong JSON type (for example `"atEffectiveDate": "true"`
        or a non-object `metadata`) return 400 before applying the revert. A JSON
        `null` option uses its default. The complete body, including trailing
        whitespace, counts towards the 4 MiB limit; exceeding it returns 413.
        Signed requests use `application/json` (including MIME parameters) with
        `request` and standard-base64 `payload`. Either signing header, even if
        empty, selects this wrapper; with neither header present, the ordinary REST body applies.
        Runtime headers choose the representation from the documented anyOf.
        The signed protobuf batch must
        equal the route/body/Idempotency-Key-derived batch in full. Supply exactly
        one nonempty Formance-Signing-Key-Id and Formance-Signature header; the

        empty or repeated signing headers, invalid base64 and wrong signature

  /v3/{ledgerName}/bulk:
    post:
      summary: Bulk operations
      description: |
        Execute multiple operations (create transactions, add metadata,
        revert transactions, delete metadata) in a single request. Requires
        `ledger:write` scope.

        With `atomic=true`, all elements target the URL's ledger and are
        submitted as one batch. `Idempotency-Key` identifies that whole batch;
        per-element `ik` values are ignored. With `atomic=false`
        (default), each element is submitted separately under its own
        `ik`; the header is ignored.

        `continueOnFailure` controls sequential continuation and business-error
        status rollup. It does not allow partial application of an atomic
        batch. Non-atomic failures can follow already committed elements:
        inspect every result and preserve the original identities when retrying.
        A timeout or infrastructure failure does not prove that work was not
        committed. This contract does not enable automatic SDK retries.

        The response status is decided in three tiers:

        1. **Request-level failures** (before per-element processing):
           malformed body → `400`, missing/insufficient scope → `401` or
           `403`, too many elements → `413`. Exceeding the byte limit while
           decoding the body currently returns `400`.
           Returned unconditionally, `continueOnFailure` does not apply.
        2. **Infrastructure failures during processing** (transport
           timeout, cache-horizon exceeded, storage error): the overall
           status is `503` for retryable failures and `500` otherwise,
           regardless of `continueOnFailure`. Callers
           must inspect the element outcomes before deciding what to retry.
        3. **Per-element errors during processing**: each element's error
           carries the HTTP status it would surface as a single request
           (via the same mapping `handleError` uses). The top-level
           status is the "worst" of them, with `continueOnFailure`
           applying only to per-element business failures (4xx):
           - Business failures (validation, not-found, conflict,
             precondition — 4xx, except authentication/permission): rolled up per
             `continueOnFailure`. `true` → `200`; `false` (default) →
             the highest 4xx among failing elements (typically `400`).
           - Authentication and permission failures: `401`/`403`, regardless
             of `continueOnFailure`, with all processing outcomes retained.
           - Resource exhaustion (`KindResourceExhausted`, `429`), including
             rate limits and permanent authoritative-sequence exhaustion:
             surface unconditionally as `429`.
           - Retryable infrastructure failures (leader loss,
             cache-horizon exceeded, `KindUnavailable`): surface as
             `503` with `Retry-After: 1`, regardless of
             `continueOnFailure`.
           - Non-retryable infrastructure failures (transport / storage
             errors, `KindInternal`, unclassified): surface as `500`.
           - Aborted elements (`context.Canceled` from the sequential
             runner after a prior failure): contribute nothing — the
             originating error drives the rollup.
        Signed requests use `application/json` (including MIME parameters) with
        `request` and standard-base64 `payload`. Either signing header, even if
        empty, selects this wrapper; with neither header present, the ordinary REST body applies.
        Runtime headers choose the representation from the documented anyOf.
        The signed protobuf batch must
        equal the route/body/Idempotency-Key-derived batch in full. Supply exactly
        one nonempty Formance-Signing-Key-Id and Formance-Signature header; the
        latter is a standard-base64 Ed25519 signature of 64 decoded bytes. Missing,
        empty or repeated signing headers, invalid base64 and wrong signature
        length return 400. Signing headers with a non-JSON or missing content type return 415.
        Signature enforcement
        returns 401 `UNAUTHENTICATED` when required but absent and 403
        `PERMISSION_DENIED` for invalid, unknown/revoked-key or mismatched
        signatures. Malformed signed envelopes return 400. The complete
        wrapper counts toward the 4 MiB body limit. JWT scopes still apply.
        Signing requires a nonempty array and `atomic=true` (otherwise 400).
        The header key applies; per-element `ik` is ignored. Authentication
        and permission failures remain 401/403 even with continueOnFailure;
        processing errors preserve every element outcome.

      summary: Add an event sink
      description: |
        Adds a named event sink to the cluster. Requires `ledger:WriteOps` scope.
        The body is a direct SinkConfig in protobuf JSON form, without a config
        wrapper. A non-empty name and exactly one sink type are required.
        Unknown fields, malformed protobuf JSON and multiple oneof members are
        rejected with `INVALID_REQUEST`. Sink-specific connection settings and
        credentials are not validated by business admission; successful creation
        does not guarantee that the sink can connect or publish events.
        `batchSize` above 100000 returns `SINK_BATCH_SIZE_TOO_LARGE` (400).
        An existing name returns `SINK_ALREADY_EXISTS` (409).

      summary: Drop an index from a ledger

        Removes an index from a ledger. The path parameter carries the target
        `IndexID` in canonical form (e.g. `metadata:TARGET_TYPE_ACCOUNT:color`,
        `tx_builtin:TX_BUILTIN_INDEX_TIMESTAMP`). Requires `ledger:WriteLedger` scope.

        The drop is idempotent. An `IndexID` that has no registry entry on the
        ledger (never created, or already dropped) also answers `204`, and each
        committed drop appends a `DROP_INDEX` entry to the ledger log. A
        mistyped canonical id is therefore not reported; read the index with
        `GET /v3/{ledgerName}/indexes/{canonicalId}` first when the caller must
        know that it exists. `404` means that the ledger does not exist.

      description: |
        Read consistency. `linearizable` (the default) runs a Raft ReadIndex
        barrier and waits for the receiving node to apply up to it. `stale`
        serves the read from the receiving node's own store, with no barrier
        and no forwarding to the leader, so the answer may lag the leader.
        Matching ignores case and surrounding whitespace. An unknown value, or a
        repeated or comma-joined header, returns `400 INVALID_REQUEST` on every
        `/v3` route, writes included; a valid value has no effect on writes. The
        gRPC equivalent is the `x-consistency` request metadata.

    QueryProfile:

      description: |
        Set to any non-empty value to receive the query profile in the
        `X-Query-Profile-Result` response header.

        The profile reports server-side request timing (how long the server spent
        handling the request, broken down into prepare / execute / read-barrier /
        deliver phases) plus the query execution plan. Use it to tell a slow
        network from a slow server: `serverDurationUs` is the
        consumer-independent server cost, and it excludes both the
        caller-requested read barrier and response delivery.

        Supported on the transactions list, accounts list, aggregated volumes and
        prepared-query execution endpoints. The equivalent gRPC opt-in is the
        `x-query-profile` request metadata, answered in the
        `x-query-profile-result-bin` trailer; `serverDurationUs` has the same
        definition on both surfaces, so the two are directly comparable.

    ListFilter:

      required: false
      schema:
        type: string
      description: |
        A filter, accepted in EITHER of two interchangeable representations that
        parse to the same filter and are validated against the same per-target
        rules:

          - **Textual** — the human-readable filter grammar, e.g.
            `metadata[status] == "active"`, `address ^= "users:"`,
            `metadata[a] == "x" and metadata[b] == "y"`. Passed verbatim as the
            query-parameter value (URL-encoded).
          - **Structured** — the JSON QueryFilter DSL (see the `QueryFilter`
            schema: `$and`/`$or`/`$not` + `$match`/`$gt`/`$exists`/…). Passed by
            URL-encoding the JSON object as the query-parameter value.

        A condition that is not valid on the endpoint's target (e.g. a
        transaction-only condition on the accounts list) is rejected with 400.
        This generic filter is AND-combined with any convenience parameters the
        endpoint also exposes (e.g. the transactions `startDate`/`endDate`
        timestamp range). Selections that used to have dedicated aliases are
        expressed through this filter: an account address prefix via
        `filter=address ^= "users:"`, a transaction reference via
        `filter=reference == "..."` or `filter={"$match":{"reference":"..."}}`
        (URL-encoded).

        Both representations cover the same fields under the same names:
        `metadata[<key>]`, `address`, `source`, `destination`, `reference`,
        `reverted`, `ledger`, `id`, `timestamp`, `insertedAt`, `revertedAt`,
        `logId`, `date` (e.g. textual `id > 100 and reverted == false` or
        structured `{"$and":[{"$gt":{"id":100}},{"$match":{"reverted":false}}]}`).

        Date fields accept either an RFC3339 timestamp or raw Unix microseconds,
        in both representations: on transactions `timestamp` / `insertedAt` /
        `revertedAt` (e.g. textual `filter=timestamp >= "2023-11-14T22:13:20Z"`
        or structured `filter={"$gte":{"timestamp":"2023-11-14T22:13:20Z"}}`), and
        on logs `date` (e.g. `filter=date >= "2023-11-14T22:13:20Z"`). An RFC3339
        value before the Unix epoch (1970-01-01) is rejected with 400.

        Note: the bare audit fields (`outcome`, `ledger`, `seq`, `proposal_id`,
        `timestamp`, `log_seq`, `caller_subject`, `order_type`,
        `idempotency_key`) are valid only on the audit-entries endpoint, where
        both representations resolve them against the audit target.

  headers:
    QueryProfileResult:
      description: |
        Query profile for this request, returned only when the request carried the
        `X-Query-Profile` header. The value is the base64 (standard alphabet)
        encoding of a serialized `QueryProfile` protobuf message
        (`misc/proto/bucket.proto`).

        Key durations, all in microseconds:

          - `serverDurationUs` — consumer-independent server cost: request entry
            to response-ready, excluding the read barrier and response delivery.
            Cannot be moved by a slow client. Over HTTP, request entry is the
            router chain just before authentication; over gRPC it is the
            handler's first statement, because grpc-go unmarshals the request
            before dispatching. It does NOT include row serialization.
          - `prepareDurationUs` — authentication, query/body decoding, validation
            and filter compilation.
          - `executeDurationUs` — query execution (contains
            `indexDurationUs` + `enrichmentDurationUs`).
          - `barrierDurationUs` — time blocked on caller-requested read
            consistency waits. Excluded from `serverDurationUs`. Measures LOCAL
            waits only, and counts one that fails or is superseded: see
            `forwarded`.
          - `deliverDurationUs` — response serialization and transport hand-off.
            Excluded from `serverDurationUs`. Always 0 over HTTP: this header
            must be flushed before the response body, so the body write is out
            of reach. It is populated for gRPC server streams.
          - `firstRowDurationUs` — always 0 over HTTP (the response is
            buffered); populated for gRPC server streams.
          - `forwarded` — true when another node served the read. Its barrier and
            execution are then folded into `executeDurationUs`, so the breakdown
            describes the local hop only. `barrierDurationUs` then covers the
            local waits only: 0 means none happened (not "no barrier was
            needed"), non-zero means a `ReadIndex` attempt failed and caused
            the forward. Do not infer the remote node's health from it.

        For a latency objective, pick a total and state which: `serverDurationUs`
        is client-independent but omits serialization, while
        `serverDurationUs + deliverDurationUs` is the complete server-side cost
        but absorbs consumer back-pressure on a gRPC stream. Neither is unbiased
        on a streaming read.

    PageToken:
      type: string
      description: |
        Page token of a paged list. Clients normally pass back the `next` or
        `previous` value of a previous response verbatim; building one by hand
        is supported.

        A token is base64url (unpadded, RFC 4648 §5) of the JSON object
        `{"key": <string>, "back": <bool>}`. Both fields are omitted when empty,
        and unknown fields are rejected. `key` is a position in the endpoint's
        textual form:

          - transactions: decimal transaction id
          - logs: decimal ledger-local log id
          - audit entries: decimal audit sequence
          - accounts: address
          - ledgers and numscripts: name
          - signing keys: key id
          - prepared queries: decimal id for TRANSACTIONS and LOGS targets,
            address for ACCOUNTS
          - index inspection: base64url of the encoded metadata value

        Both directions exclude the key and return rows in the requested order
        (`reverse` included):

          - `{"key": K}` serves the rows strictly after K;
          - `{"key": K, "back": true}` serves the page that ends strictly
            before K;
          - `{"back": true}` serves the last page;
          - an absent or empty token, or `e30` (`{}`), serves the first page.

        On a forward page, `next` is set when a further row follows the page,
        and `previous` whenever the request carried a key. On a back page,
        `previous` is set when a further row precedes the page, and `next`
        whenever the request carried a key. A first page therefore has no
        `previous`, and the last page requested with `{"back": true}` has no
        `next`. A malformed token, or a key that is not a valid position for
        the endpoint, is rejected with 400 `INVALID_REQUEST`.

        and out-of-range values are rejected. String values must not contain
        NUL bytes. A value is limited to 16384 bytes by default; the effective
        ceiling comes from the cluster policy (`--metadata-max-value-bytes`).
        Exceeding it returns 400 with reason `METADATA_LIMIT_EXCEEDED` for a
        new or expired idempotency key. A live retained key with matching content
        returns its historical outcome; different content returns 409 with reason
        `IDEMPOTENCY_KEY_CONFLICT`. Requests without a key retain the limit error. Fresh policy refusals are
        audited without business effects; keyed refusals replay while retained,
        even if the policy is later loosened.

            Opt-in continue-on-failure list for this entry. When the FSM
            would otherwise reject the underlying order with a business
            error whose typed reason matches one of these entries, the
            order is recorded as an `OrderSkippedLog` (no state mutation)
            and the bulk result's `data` surfaces the skip context.
            Reasons outside the per-action business whitelist (structural
            / internal reasons) are rejected at admission. Accepted
            reasons per action on this REST endpoint:
              - `CREATE_TRANSACTION` → `TRANSACTION_REFERENCE_CONFLICT`
              - `REVERT_TRANSACTION` → `TRANSACTION_ALREADY_REVERTED`
              - `DELETE_METADATA`    → `METADATA_NOT_FOUND`
            The FSM also supports skipping `ADD_ACCOUNT_TYPE`
            (`ACCOUNT_TYPE_ALREADY_EXISTS`) and `REMOVE_ACCOUNT_TYPE`
            (`ACCOUNT_TYPE_NOT_FOUND`), but those actions are **gRPC-only**:
            the REST bulk endpoint does not accept account-type actions (see
            the `action` enum above), so their reasons are not offered here.
            Empty (default) preserves the historical fail-on-error
            behaviour.

    QueryFilter:
      type: object
      description: >-
        Recursive filter expression using the Formance query DSL (aligned with
        the v2 API). Each node is an object with **exactly one** top-level
        `$`-prefixed operator key.


        Combinators:

        - `{"$and": [QueryFilter, ...]}` — all sub-filters must match (non-empty).

        - `{"$or":  [QueryFilter, ...]}` — at least one sub-filter matches (non-empty).

        - `{"$not": QueryFilter}` — negates a single sub-filter.


        Leaf conditions are a single-key operator whose value is a
        `{ "<field>": <value> }` map with exactly one field:

        - `{"$match": {"<field>": <value>}}` — equality; for `address`/`source`/`destination`
          a trailing `:` means prefix match, otherwise exact.

        - `{"$gt"|"$gte"|"$lt"|"$lte": {"<field>": <value>}}` — range bound. A closed
          range is expressed as an `$and` of a lower and an upper bound on the same field.

        - `{"$exists": {"metadata": "<key>"}}` — the metadata key is present.

        - `{"$exists": {"asset": "<assetRef>"}}` — the account has ever held the asset
          (`assetRef` is `BASE` or `BASE/PRECISION`, e.g. `USD/2`). Requires a READY
          `account-asset` index.


        Supported fields: `metadata[<key>]`, `address`, `source`, `destination`,
        `reference`, `reverted` (bool), `ledger`, `id`, `timestamp`, `insertedAt`,
        `revertedAt`, `logId`, `date`. Not every field applies to every query target;
        a field that does not apply is rejected. On the numeric built-ins
        (`id`, `timestamp`, `insertedAt`, `revertedAt`, `logId`, `date`) use
        `$gt`/`$gte`/`$lt`/`$lte` for ranges; `$match` is an equality (the closed
        range from the value to itself). On the audit-entries endpoint only, the
        bare audit fields (`outcome`, `ledger`, `seq`, `proposal_id`, `timestamp`,
        `log_seq`, `caller_subject`, `order_type`, `idempotency_key`) replace the
        `ledger`/`timestamp` meanings above: `$match` on any of them, range
        operators on the numeric ones, no `$param` values.
        The log-only fields (`logId`, `date`, `ledger`) are valid only when the
        prepared query targets `LOGS`; they are rejected on `ACCOUNTS` and
        `TRANSACTIONS` targets.


        A value is either a JSON literal or a parameter reference
        `{"$param": "<name>"}`, resolved at prepared-query execution time. A JSON
        `null` in value position is rejected. uint64 fields
        (`id`, `timestamp`, `insertedAt`, `revertedAt`, `logId`, `date`) are carried
        as decimal strings to stay lossless above 2^53. The date-semantic fields

        whitespace-only textual expression are invalid. Responses echo a stored

        `mode=AGGREGATE_VOLUMES` returns `aggregateResult`. (The query `target`
        — ACCOUNTS, TRANSACTIONS or LOGS — selects the row type inside the
        cursor, not which envelope field is set: `accountData`,
        `transactionData` or `logData` respectively. LOGS is a usable
        prepared-query target: `query.Execute` hydrates `logData` for it.) Both
        payloads use the same camelCase encoding as the equivalent non-prepared
        endpoints
