Um auf das vorherige Codebeispiel zurückzukommen, **FastAPI** wird:

* Validieren, dass es eine `item_id` im Pfad für `GET`- und `PUT`-Requests gibt.
* Validieren, ob die `item_id` vom Typ `int` für `GET`- und `PUT`-Requests ist.
    * Falls nicht, sieht der Client einen hilfreichen, klaren Fehler.
