    `from starlette.responses import JSONResponse` を利用することもできます。

    **FastAPI** は `fastapi.responses` と同じ `starlette.responses` を、開発者の利便性のために提供しています。しかし有効なレスポンスはほとんどStarletteから来ています。 `status` についても同じです。

## OpenAPIとAPIドキュメント

ステータスコードとレスポンスを直接返す場合、それらはOpenAPIスキーマ (APIドキュメント) には含まれません。なぜなら、FastAPIは何が返されるのか事前に知ることができないからです。
