## Other responses

- `400` — The request body or query string was invalid (unknown key, wrong type, or missing required field). Strict schemas reject unknown keys — including `brandId`, which is always resolved from the API key.
- `401` — The API key was missing, invalid, or revoked.
- `403` — The caller does not have the required `domains` permission.
- `409` — The same `Idempotency-Key` was reused with a different request body.
- `429` — The request hit the rolling rate limit window.
- `500` — Unexpected internal error.
