!!! check "**FastAPI**'a nasıl ilham oldu?"
    Hug, APIStar'ın çeşitli kısımlarında esin kaynağı oldu ve APIStar'la birlikte en umut verici bulduğum araçlardan biriydi.

    **FastAPI**, Python tip belirteçlerini kullanarak parametre belirlemede ve API'ı otomatık tanımlayan bir şema üretmede de Hug'a esinlendi.
