Например, модель выше описывает такой JSON "объект" (или Python `dict`):

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

...так как `description` и `tax` являются необязательными (со значением по умолчанию `None`), такой JSON "объект" тоже будет корректным:

```JSON
{

Это не является ограничением **FastAPI**, это часть протокола HTTP.

Вы можете сделать загрузку файла необязательной, используя стандартные аннотации типов и установив значение по умолчанию `None`:
