FastAPI bu dönüş tipini şunlar için kullanır:

* Dönen veriyi **doğrulamak** (validate).
    * Veri geçersizse (ör. bir field eksikse), bu *sizin* uygulama kodunuzun bozuk olduğu, olması gerekeni döndürmediği anlamına gelir; bu yüzden yanlış veri döndürmek yerine server error döner. Böylece siz ve client’larınız, beklenen veri ve veri şeklinin geleceğinden emin olabilirsiniz.
* OpenAPI’deki *path operation* içine response için bir **JSON Schema** eklemek.

Mais quand même, FastAPI s'est inspiré de Requests.

**Requests** est une bibliothèque pour _interagir_ avec les API (en tant que client), tandis que **FastAPI** est une bibliothèque pour _créer_ des API (en tant que serveur).

Ils sont, plus ou moins, aux extrémités opposées, se complétant l'un l'autre.
