**FastAPI** gives you the following:

### Based on open standards { #based-on-open-standards }

* [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification) for API creation, including declarations of <dfn title="also known as: endpoints, routes">path</dfn> <dfn title="also known as HTTP methods, as POST, GET, PUT, DELETE">operations</dfn>, parameters, request bodies, security, etc.

Marshmallow와 Webargs는 plug-in 형태로 검증, parsing, serialization을 제공합니다.

하지만 문서화는 여전히 부족했습니다. 그래서 APISpec이 만들어졌습니다.

이는 여러 framework를 위한 plug-in이며(Starlette용 plug-in도 있습니다).

작동 방식은, 각 route를 처리하는 함수의 docstring 안에 YAML 형식으로 schema 정의를 작성하고,

그로부터 OpenAPI schema를 생성합니다.

Flask, Starlette, Responder 등에서 이런 방식으로 동작합니다.

하지만 다시, Python 문자열 내부(큰 YAML)에서 micro-syntax를 다루어야 한다는 문제가 있습니다.

/// note | Détails techniques

Dans la spécification OpenAPI, cela s’appelle l’[objet Operation](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object).

///

Il contient toutes les informations sur le chemin d’accès et est utilisé pour générer la documentation automatique.

Il inclut les `tags`, `parameters`, `requestBody`, `responses`, etc.

Ainsi, nous obtenons un modèle Pydantic à partir des données d'un autre modèle Pydantic.

#### Déballer un `dict` et ajouter des mots-clés supplémentaires { #unpacking-a-dict-and-extra-keywords }

Et en ajoutant ensuite l'argument nommé supplémentaire `hashed_password=hashed_password`, comme ici :
