Errors

Status	Code	When
400	`bad_request`	The request could not be parsed: malformed JSON, an invalid cursor, or a query parameter of the wrong shape.
400	`validation_error`	The body or query failed validation. `details` lists each failing field with a `path` and a `message`.
401	`unauthorized`	No usable API key: the Authorization header is missing or malformed, or the key is unknown, revoked or expired. The three are deliberately indistinguishable.
403	`forbidden`	The key is valid but lacks the scope this endpoint requires, or the request came from an address outside the key’s IP allowlist. The message says which.
403	`account_suspended`	The account this key belongs to is suspended. Rotating the key will not help; contact support.
404	`not_found`	No such resource in this account. A resource that exists in another account also returns this.
422	`unprocessable`	The request was well-formed but cannot be carried out. `reason` is a stable string saying why (for example `outside_window` or `stage_not_in_pipeline`).
429	`rate_limited`	The per-key budget, or the per-IP budget for failed authentication, is exhausted. Honour `Retry-After` before retrying.
500	`internal`	Something failed on our side. Safe to retry with the same Idempotency-Key; quote `request_id` if it persists.
