結果として、このアプリ内では `admin` モジュールの各 *path operation* が次のようになります:

* prefix は `/admin`
* タグは `admin`
* 依存関係は `get_token_header`
* レスポンスは `418` 🍵

ただし、これはこのアプリ内のその `APIRouter` にのみ影響し、それを使用する他のコードには影響しません。

例えば、他のプロジェクトでは同じ `APIRouter` を別の認証方式で使うこともできます。

### *path operation* を追加 { #include-a-path-operation }
