## Other responses

- `400`: The request is malformed or violates a field constraint. Match behavior on the response code field.
- `401`: missing-api-key: no bearer. malformed-api-key: the header or the key has the wrong shape, or an agent token was sent to a route that accepts keys only. unauthorized: the key is unknown, expired, revoked, or of the kind this route refuses, or the agent token is invalid or expired.
- `403`: project-archived: the project of the key, or the project an agent token names, is archived. Unarchive it in the console to resume. insufficient-scope: the agent token does not carry the scope of the route.
- `404`: No matching memory or source exists in the selected project.
- `429`: The plan's requests per minute are exceeded. This refusal carries no body.
- `default`: Any other failure uses the same JSON error envelope.
