- `500`: Internal failure (`INTERNAL_ERROR`, `CACHE_ERROR`). (schema: [ErrorResponse](/docs/reference/data-model.md))

Every response carries `X-Request-Id` and, when metered, `X-RateLimit-Limit` / `X-RateLimit-Remaining` / `X-RateLimit-Reset`. Errors use `{"error": {"code", "message"}}`. See [Errors](/docs/getting-started/errors.md).
