markers

GET /markers​

List behavioral markers

Markers of the resolved project + environment, newest first (cursor pagination, 003 §1). Paused markers are listed with status: paused; deleted markers are gone.

Operation ID: listMarkers · Service: gateway-api

Authentication​

  • apiKey (http (bearer)) — Project API key (003 §2): tsk_live_… or tsk_test_… in Authorization: Bearer. Scoped to exactly one project + environment; scopes are a subset of ingest, read, admin. Keys are stored hashed and shown once at creation.
  • consoleSession (http (bearer)) — Console session (003 §2): Identity Platform JWT. Data-plane calls add X-Tessera-Project + X-Tessera-Environment headers, validated against org membership.

Parameters​

NameInRequiredTypeDescription
cursorquerynostringOpaque pagination cursor from a previous response's next_cursor.
limitquerynointegerPage size (cursor pagination, 003 §1). Maximum 200.

Pagination​

Cursor pagination (003 §1): pass limit (max 200) and cursor; the response is the pagination envelope — data plus next_cursor (null on the last page).

defaultErrorEnvelopeError response (003 §1). Every non-2xx response uses this envelope; the HTTP status matches error.code. Rate-limited requests get 429 resource_exhausted with retry_after_seconds and a Retry-After header; the X-RateLimit-* headers ride on EVERY response, success or error (003 §1; plan-driven per API key + endpoint class — WP-B2). A 503 unavailable carries retry_after_seconds too for a lock-wait timeout (SQLSTATE 55P03), a rule preview at capacity (preview_capacity_exhausted), or a label preview during which the erasure of every entity holding its censor clock began (label_preview_clock_entity_erased): how long to wait before retrying.

POST /markers​

Create a behavioral marker

Creates a versioned, output-only marker (WP-C7 req 6). The pattern is validated by THE grammar validator — unknown node kinds, ops or fields and every bound (boolean depth <= 3, <= 8 leaves, 2-4 sequence steps, sum requires attr_key, ...) fail with 400 invalid_argument naming the violation. The server owns marker_id, version (starts at 1) and pattern_fingerprint. name is unique per project + environment (409 already_exists) and is registered into leakage-policy deny-pattern scanning (WP-C5 R4). Slot enablement references deployment slots of the same environment; at most 32 active markers may be enabled on one slot — the 33rd is 400 failed_precondition (reason marker_slot_cap_exceeded).

Parameters​

NameInRequiredTypeDescription
Idempotency-KeyheadernostringIdempotency key accepted by all POSTs (003 §1): 24 h dedup window, keyed per project. POSTs that are reads (batchSlotScores, scoreSlotEvent, deriveSlotBands, validateSourceRawPreset, sampleSource, watchEventFeedHeads and the preview operations: previewSourceMapping, previewCatalogMapping, previewLabel, previewPatternLabel, previewMarker, previewDatasetEligibility, previewSlotAudience, previewSharedCheckpointImport, previewSlotAtlasInquiry) accept the key but never replay a stored response: a retry with the same key is executed again (and metered again) against current data. A stored response that names an entity is removed when that entity is erased. A key that already answered answers only a retry of the request that stored its response: the same caller, environment, operation, path, query, scoping headers and body (a JSON body by its content, a gzip body by its inflated content). The same key with any other request is 409 already_exists with details[0].reason idempotency_key_reused, and that request is not run. The window holds no in-flight marker: two first requests sent at once can both run. A response stored by a release before this rule cannot be matched to its request and is refused the same way until it expires; send the request again with a new key. A body over 8 MiB (ingest: over its 5 MiB request limit) is run and its response is not stored. The ingest batch (POST /events) is the exception, except for an application's credentials: under a key that answered another batch it runs again, uncached, and its events' ids deduplicate them; so it does when its stored response cannot be checked. The operations that return a one-time secret store their response sealed: the stored copy opens only for the same key and credential, and one that cannot be opened is 409 idempotency_key_reused. While the server cannot check a stored response (it cannot read the key that checks it, for one), the request is 503 unavailable with Retry-After: retry with the same key. An operation whose handler claims the key itself answers the same 503, before it runs, while the key-hash pepper cannot be read; any other request sent with a key runs meanwhile, and its response is not stored.

Idempotency​

This operation accepts an Idempotency-Key header (003 §1): within 24 hours, keyed per project and caller, a retry of the same request gets the first response, and the same key with another request is 409 already_exists (idempotency_key_reused). See the Idempotency-Key parameter for the exceptions.

GET /markers/{marker_id}​

Get one behavioral marker

The stored marker. Another tenant's marker id is indistinguishable from a missing one (404 not_found, 003 §3).

DELETE /markers/{marker_id}​

Delete a behavioral marker

Removes the marker from future evaluations. Stored marker state on entity rows is dropped by the next marker-aware state write; already-emitted marker.fired deliveries are unaffected.

PATCH /markers/{marker_id}​

Update a behavioral marker

Partial update (WP-C7 req 6): omitted members are unchanged and an explicit null is 400 invalid_argument. A pattern whose canonical fingerprint differs increments version and recomputes pattern_fingerprint — later firings carry the new pair, and the new version starts its own episodes. status: paused stops evaluation entirely (paused markers are never evaluated). Slot or status changes re-check the 32-marker slot cap (400 failed_precondition); a renamed marker re-registers its name.

POST /markers:preview​

Dry-run an unsaved marker pattern

Marker preview (WP-C7 req 11; WP-C6 R18 mechanics): validates the UNSAVED pattern exactly like POST /markers, samples up to sample_entities (default 50, at most 200) entities of entity_type from the newest days of that type's events (a pattern that can match silence, with a not or an at-most lte leaf, samples evenly by key hash from every entity of the type seen in the whole read range, so entities that went quiet are included) and evaluates the pattern through THE evaluator over each entity's newest 1,024 events at as_of = now. TES-031: the read reaches back to the pattern's lookback (the longest window_agg or relative span; a sequence reads all history) within the shared preview read budget (512 data files, 32 MiB or 12 s of reading). When it covers the lookback the result is the full-history one (an entity with exactly 1,024 events in reach may be flagged truncated conservatively); otherwise the example's window.truncated is true and the entity counts in truncated_entities. The preview runs under the same 25 s deadline (503 unavailable, details[0].reason: marker_preview_deadline_exceeded, with a request id) and process limits as POST /labels:preview, and examples include active and inactive entities when both occur. Read-only: nothing is persisted and no name or policy is registered. Entity ids only ever appear as entity_hash (002 §3). An entity whose erasure has begun is left out and not replaced, so sampled_entities can be smaller than sample_entities.

The window holds no in-flight marker: two first requests sent at once can both run. A response stored by a release before this rule cannot be matched to its request and is refused the same way until it expires; send the request again with a new key.

Idempotency​

This operation never replays a stored response (003 §1): a retry carrying the same Idempotency-Key runs again, against current data.

MarkerPreviewRequest

Responses​

StatusSchemaDescription
200MarkerPreviewResponseThe dry-run evaluation over the sampled entities.
defaultErrorEnvelopeError response (003 §1). Every non-2xx response uses this envelope; the HTTP status matches error.code. Rate-limited requests get 429 resource_exhausted with retry_after_seconds and a Retry-After header; the X-RateLimit-* headers ride on EVERY response, success or error (003 §1; plan-driven per API key + endpoint class — WP-B2). A 503 unavailable carries retry_after_seconds too for a lock-wait timeout (SQLSTATE 55P03), a rule preview at capacity (preview_capacity_exhausted), or a label preview during which the erasure of every entity holding its censor clock began (label_preview_clock_entity_erased): how long to wait before retrying.

Errors​

Every non-2xx response uses the 003 §1 error envelope; error.request_id matches the X-Request-Id response header, and the HTTP status always matches error.code:

{
  "error": {
    "code": "invalid_argument",
    "details": [
      {
        "type": "field_violation"
      }
    ],
    "message": "human-readable",
    "request_id": "req_01hxample"
  }
}

Closed error-code set (003 §1): invalid_argument, unauthenticated, permission_denied, not_found, already_exists, failed_precondition, resource_exhausted, internal, unavailable.

resource_exhausted responses (HTTP 429) additionally carry retry_after_seconds. See ErrorEnvelope.
