Le fichier **FastAPI** le plus simple possible pourrait ressembler à ceci :

Copiez cela dans un fichier `main.py`.

Démarrez le serveur en direct :

`APIRouter`’lar "mount" edilmez; uygulamanın geri kalanından izole değildir.

Çünkü *path operation*’larını OpenAPI şemasına ve kullanıcı arayüzlerine dahil etmek istiyoruz.
