### Крок 2: створюємо екземпляр `FastAPI`

```Python hl_lines="3"
{!../../docs_src/first_steps/tutorial001.py!}
```
Змінна `app` є екземпляром класу `FastAPI`.

Це буде головна точка для створення і взаємодії з API.

データの変換、検証、文書化などはすべて通常通りに動作します。

このようにして、モデル間の違いだけを宣言することができます:

```Python hl_lines="9  15 16  19 20  23 24"
{!../../docs_src/extra_models/tutorial002.py!}
```

## `Union`または`anyOf`

レスポンスを２つの型の`Union`として宣言することができます。

OpenAPIでは`anyOf`で定義されます。

そのためには、標準的なPythonの型ヒント<a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>を使用します:
