200Successful Response

401Authentication failed. No Authorization: Bearer header, malformed JWT, expired passport, or invalid signature. Identity is not established—unlike 403, the caller is not treated as an authenticated subject. Typical error.code values: INVALID_AUTHORIZATION, AUTHORIZATION_EXPIRED.

403Authorization failed. The bearer token was accepted, but the caller lacks required OAuth scopes or permissions, or an upstream service denied access to the resource. Typical error.code values: MISSING_PERMISSIONS, UPSTREAM_ACCESS_DENIED.

404Resource not found. The path id does not exist, a parent resource in a nested URL is missing, or the object is not visible. Typical error.code: RESOURCE_NOT_FOUND.

429Rate limiting (reserved). This BFF process does not currently return 429. Clients that reach the API through a gateway or CDN should still be prepared for 429 and Retry-After from those layers.
