## OpenAPI and API docs { #openapi-and-api-docs }

If you return additional status codes and responses directly, they won't be included in the OpenAPI schema (the API docs), because FastAPI doesn't have a way to know beforehand what you are going to return.

It includes the `tags`, `parameters`, `requestBody`, `responses`, etc.

This *path operation*-specific OpenAPI schema is normally generated automatically by **FastAPI**, but you can also extend it.

/// tip

This is a low level extension point.

If you only need to declare additional responses, a more convenient way to do it is with [Additional Responses in OpenAPI](additional-responses.md).
