## Die Instanz als Abhängigkeit verwenden

Dann könnten wir diesen `checker` in einem `Depends(checker)` anstelle von `Depends(FixedContentQueryChecker)` verwenden, da die Abhängigkeit die Instanz `checker` und nicht die Klasse selbst ist.

Und beim Auflösen der Abhängigkeit ruft **FastAPI** diesen `checker` wie folgt auf:

```Python
checker(q="somequery")
```

## Usar la instance como una dependencia

Luego, podríamos usar este `checker` en un `Depends(checker)`, en lugar de `Depends(FixedContentQueryChecker)`, porque la dependencia es la instance, `checker`, no la clase en sí.

Y al resolver la dependencia, **FastAPI** llamará a este `checker` así:

```Python
checker(q="somequery")
```
