## Responses

This guide summarizes response status codes and headers. Retrieve the deployed, authenticated OpenAPI document for the exact response body schemas and examples. The API also provides an authenticated Swagger UI; opening it in a browser does not automatically attach a bearer token.

Error responses use `application/problem+json`. The response's stable `code` and `type` map to the [error-code reference](/errors).
