そして、これを `FastAPI` appを作る際に使います。

それから、以下のように `OPENAPI_URL` という環境変数を空文字列に設定することによってOpenAPI (UIドキュメントを含む) を無効化することができます。

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

すると、以下のように `/openapi.json`, `/docs`, `/redoc` のどのURLにアクセスしても、 `404 Not Found` エラーが返ってくるようになります。

```JSON
