そして、それを属性の型として使用することができます:

これは **FastAPI** が以下のようなボディを期待することを意味します:

```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"
    }
}
```

보낼 페이로드에 대해서도 자동 완성이 제공됩니다:

/// tip | 팁

`name`과 `price`에 대한 자동 완성은 FastAPI 애플리케이션에서 `Item` 모델에 정의된 내용입니다.

전송하는 데이터에 대해 인라인 오류도 표시됩니다:
