## Other responses

- `401`: No valid credential presented — missing/invalid API-key headers, or an invalid/expired session token.
- `403`: Authenticated but not permitted. Three distinct causes: the session user is not invited (`Invite required`), the API key lacks the operation's scope, or API-key access to the requested venue is switched off (`API access is disabled for <provider>`). Admin and API-key callers bypass the invite check; session and admin callers bypass scope and venue checks.
- `422`: Request failed FastAPI parameter validation.
- `429`: Rate limit exceeded for this route's sliding window, keyed on the session `sub` when authenticated and on the trusted client IP otherwise. Honor `Retry-After`. A per-API-key data ceiling (set per credential) rejects with `{"detail": "API key data rate limit exceeded"}` instead of the `error` envelope below.
- `500`: Search-index rebuild failed on a cache miss.
