例えば、上記のモデルは以下の様なJSON「`オブジェクト`」(もしくはPythonの `dict` ) を宣言しています:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...`description` と `tax` はオプショナル (デフォルト値は `None`) なので、以下のJSON「`オブジェクト`」も有効です:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

## パラメータとして宣言

                                            <th><la:message key="labels.user_description"/></th>
                                            <td>${f:h(attributes.description)}<la:hidden
                                                    property="attributes.description"/></td>
                                        </tr>
                                        <tr>

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

This would mean that **FastAPI** would expect a body similar to:

```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"
    }
}
```

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

Это означает, что **FastAPI** будет ожидать тело запроса, аналогичное этому:

```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"
    }
}
```

* `version`: A versão da sua API, por exemplo, `2.5.0`.
* `openapi_version`: A versão da especificação OpenAPI utilizada. Por padrão, a mais recente: `3.1.0`.
* `summary`: Um resumo curto da API.
* `description`: A descrição da sua API, que pode incluir markdown e será exibida na documentação.
* `routes`: Uma lista de rotas, que são cada uma das *operações de rota* registradas. Elas são obtidas de `app.routes`.
