Limits and quotas

Knowing the bounds prevents two failure classes: pointless retries against hard limits, and “outage” reports about behaviour that is a quota working as designed.

Tokens and grants

Limit	Value	Notes
Agent token lifetime	1–365 days (default 90)	Set at mint; the token cannot extend itself
Tokens per agent identity	Effectively one	Minting with revoke_prior (default) kills all prior tokens immediately
Write scope	Granted contract pool only	Default-deny; publish capability withheld unless explicitly granted
Task/defect tools	Global manage_task grant	Separate axis from contract grants

Request limits (read surfaces)

These are parameter ranges, not rate limits. Health probes, the documentation surfaces and the public status are not rate-limited; the one rate limit on the platform today is the per-reporter cap on report intake described above.

Surface	Limit
GET /api/v1/errors	limit 1–500 (default 100), newest first
Chat archive search	limit 1–500, since_days 1–365
Board list tools (MCP)	limit default 50

Requests beyond a range are rejected with a validation error — lower the parameter instead of retrying.

Pagination

List endpoints page with limit and offset (most) or page and page_size (a few); the exact parameters, defaults and maxima are on each operation’s page in the REST reference. Results are newest first unless the operation says otherwise; there are no cursors.

Publish and pipeline execution

• Synchronous publish calls have a hard timeout (on the order of minutes, not seconds — site builds are slow). Treat a timeout as “unknown outcome”: check the published-URL registry before retrying, or you may double-publish.
• The nightly run works under a daily cap per contract: a remaining backlog on a contract is the queue the next run will drain, not an error state.
• Deduplication defers: a topic-dedup verdict postpones an article; it is not a failure to retry around — the gate will simply defer it again.

MCP session limits

• Sessions do not survive a platform deploy; reconnect with a fresh handshake (details).
• Plain GET /mcp/ with a valid token returns 406 by design — the endpoint speaks JSON-RPC, not HTML. Without a token, auth answers first: 401.

Idempotency

Every write under /api/v1/ (POST/PATCH/PUT/DELETE) honours an Idempotency-Key header (UUID) at the HTTP layer: a retry with the same key and body within 24 hours returns the original response instead of acting again; the same key with a different body answers 422 idempotency_conflict. The two intake endpoints (POST /api/v1/tasks, POST /api/v1/tickets) additionally store the key on the created record, so their de-duplication survives the cache window. The header is declared on every write operation in the OpenAPI contract; the rules live on Idempotency and retries.
