## Other responses

- `400`: The request payload or parameters are invalid.
- `401`: Authentication is missing, invalid, or expired.
- `403`: The credential is valid but may not perform the operation. `INSUFFICIENT_SCOPE`: the credential was never granted the capability the operation needs. `details.requiredScope` names it, and the `WWW-Authenticate` header carries `Bearer error="insufficient_scope"`. An OAuth client fixes this by requesting the scope; an organization API key cannot gain it. `FORBIDDEN`: the capability is present but the membership behind the credential lacks the role, or the resource belongs to another organization.
- `404`: The requested resource was not found.
- `503`: The capability is temporarily paused by an operator. Retry later.
