### OpenAPI

**FastAPI** génère un "schéma" contenant toute votre API dans le standard de définition d'API **OpenAPI**.

#### "Schéma"

Un "schéma" est une définition ou une description de quelque chose. Pas le code qui l'implémente, uniquement une description abstraite.

An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose not to enable the kube-apiserver mitigation to avoid disrupting load balancer → kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may choose not to enable the kube-apiserver mitigation to prevent performance regressions for unauthenticated clients. Authenticated requests rely...

Installez également `uvicorn` pour qu'il fonctionne comme serveur :

```
pip install uvicorn
