...et déclarez que son type est le modèle que vous avez créé : `Item`.

## Résultats

En utilisant uniquement les déclarations de type Python, **FastAPI** réussit à :

* Lire le contenu de la requête en tant que JSON.
* Convertir les types correspondants (si nécessaire).
* Valider la donnée.

    /** Constant indicating that the crawler is waiting for new URLs. */
    int WAIT_NEW_URL = 8;

    /**
     * Introduces a delay based on the specified type.
     *
     * @param type the type of delay to be introduced
     */
    void delay(int type);

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md){.internal-link target=_blank}.

You write standard Python with types:

```Python
from datetime import date

```

## `Annotated` im Typ des `q`-Parameters verwenden

Erinnern Sie sich, wie ich in [Einführung in Python-Typen](../python-types.md#typhinweise-mit-metadaten-annotationen){.internal-link target=_blank} sagte, dass Sie mittels `Annotated` Metadaten zu Ihren Parametern hinzufügen können?

Jetzt ist es an der Zeit, das mit FastAPI auszuprobieren. 🚀
