9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.

    FastAPI will use the `response_model` parameter (that includes dataclasses) to convert the response.

## Integrated middlewares { #integrated-middlewares }

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

/// note | Technical Details

For the next examples, you could also use `from starlette.middleware.something import SomethingMiddleware`.

/// tip

You can write Markdown in the `description` field and it will be rendered in the output.
