O **FastAPI** chama a classe `CommonQueryParams`. Isso cria uma "instância" dessa classe e é a instância que será passada para o parâmetro `commons` na sua função.

## Anotações de Tipo vs `Depends`

Perceba como escrevemos `CommonQueryParams` duas vezes no código abaixo:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.8+ non-Annotated

## Type annotation vs `Depends` { #type-annotation-vs-depends }

Notice how we write `CommonQueryParams` twice in the above code:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```
