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

* Überprüfen, dass es eine `item_id` im Pfad für `GET`- und `PUT`-Anfragen gibt.
* Überprüfen, ob die `item_id` vom Typ `int` für `GET`- und `PUT`-Anfragen ist.
    * Falls nicht, wird dem Client ein nützlicher, eindeutiger Fehler angezeigt.

    * Swagger UI.
    * ReDoc.

Tornando al precedente esempio, **FastAPI**:

* Validerà che esiste un `item_id` nel percorso delle richieste `GET` e `PUT`.
* Validerà che `item_id` sia di tipo `int` per le richieste `GET` e `PUT`.
    * Se non lo è, il client vedrà un errore chiaro e utile.

   *     multimap already contained the key-value pair
