## Other responses

- `400`: Bad request: `VALIDATION_ERROR`, `INVALID_JSON`. Each example says when.
- `401`: Not authenticated: `AUTH_REQUIRED`. no credentials, or an OAuth token on a route that only takes workspace keys; the key is malformed, unknown or revoked.
- `403`: Forbidden: `INSUFFICIENT_SCOPE`. Each example says when.
- `404`: Not found: `NOT_FOUND`. Each example says when.
- `409`: Conflict: `IMPORT_INCOMPLETE`. Each example says when.
- `413`: Request too large: `INVALID_REQUEST`. the body exceeds 1 MiB.
- `415`: Unsupported media type: `INVALID_REQUEST`. a write with a body that is not `Content-Type: application/json` (a key request with no body needs no Content-Type).
- `429`: Too many requests: `RATE_LIMIT`. more than 240 requests in the current minute for this workspace (REST and MCP share the limit); wait `retryAfterMs`.
- `default`: Any other refusal or failure, such as 403 CSRF (a cross-origin `Origin` header), 403 HTTPS_REQUIRED or 500 INTERNAL_ERROR, with what to do next.
