`app.add_middleware()` receives a middleware class as the first argument and any additional arguments to be passed to the middleware.

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

### `Union` in Python 3.10 { #union-in-python-3-10 }

In this example we pass `Union[PlaneItem, CarItem]` as the value of the argument `response_model`.

Because we are passing it as a **value to an argument** instead of putting it in a **type annotation**, we have to use `Union` even in Python 3.10.

If it was in a type annotation we could have used the vertical bar, as:
