**FastAPI** вызывает класс `CommonQueryParams`. При этом создается «экземпляр» этого класса, который будет передан в качестве параметра `commons` в вашу функцию.

## Аннотация типа и `Depends` { #type-annotation-vs-depends }

Обратите внимание, что в приведенном выше коде мы два раза пишем `CommonQueryParams`:

**FastAPI** llama a la clase `CommonQueryParams`. Esto crea una "instance" de esa clase y la instance será pasada como el parámetro `commons` a tu función.

## Anotación de tipos vs `Depends` { #type-annotation-vs-depends }

Nota cómo escribimos `CommonQueryParams` dos veces en el código anterior:

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