**FastAPI**は実際には**Requests**の代替ではありません。それらのスコープは大きく異なります。

実際にはFastAPIアプリケーションの*内部*でRequestsを使用するのが一般的です。

しかし、FastAPIはRequestsからかなりのインスピレーションを得ています。

**Requests**は (クライアントとして) APIと*通信*するためのライブラリであり、**FastAPI**は (サーバーとして) APIを*構築*するためのライブラリです。

これらは多かれ少なかれ両端にあり、お互いを補完し合っています。

It's not acceptable to treat an unset Provider as if the convention is requested when the convention could be set elsewhere:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}
