## Other responses

- `400`: Malformed request parameters or body. Agile requests may return `INVALID_PAGINATION` or `INVALID_IDEMPOTENCY_KEY`.
- `401`: No credential was supplied, or the supplied credential is malformed, expired, or revoked. A credential that is present but unusable is never downgraded to an anonymous request.
- `403`: Authenticated but not authorized. Either the acting user lacks the required resource permission, the key's scope ceiling excludes it, or the endpoint rejects this credential type (`CREDENTIAL_NOT_PERMITTED`).
- `404`: The resource does not exist in the parent named by the path, or is hidden from the caller. Absence and privacy denial are deliberately indistinguishable so project, organization, and private-team existence cannot be probed.
- `429`: Request rate exceeded, either globally or for this key.
- `500`: Unexpected server error.
