Volviendo al ejemplo de código anterior, **FastAPI**:

* Validará que haya un `item_id` en el path para requests `GET` y `PUT`.
* Validará que el `item_id` sea del tipo `int` para requests `GET` y `PUT`.
    * Si no lo es, el cliente verá un error útil y claro.
* Comprobará si hay un parámetro de query opcional llamado `q` (como en `http://127.0.0.1:8000/items/foo?q=somequery`) para requests `GET`.
