Das würde bedeuten, dass **FastAPI** einen Body wie folgt erwartet:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Wiederum, nur mit dieser Deklaration erhalten Sie von **FastAPI**:
