FastAPI es un framework web moderno, rápido (de alto rendimiento), para construir APIs con Python basado en las anotaciones de tipos estándar de Python.

Las funcionalidades clave son:

* **Rápido**: Muy alto rendimiento, a la par con **NodeJS** y **Go** (gracias a Starlette y Pydantic). [Uno de los frameworks Python más rápidos disponibles](#performance).

FastAPI é um framework web moderno e rápido (alta performance) para construção de APIs com Python, baseado nos type hints padrões do Python.

Os recursos chave são:

* **Rápido**: alta performance, equivalente a **NodeJS** e **Go** (graças ao Starlette e Pydantic). [Um dos frameworks Python mais rápidos disponíveis](#performance).

FastAPI est un framework web moderne et rapide (haute performance) pour la création d'API avec Python, basé sur les annotations de type standard de Python.

Les principales fonctionnalités sont :

* **Rapide** : très hautes performances, au niveau de **NodeJS** et **Go** (grâce à Starlette et Pydantic). [L'un des frameworks Python les plus rapides](#performance).

## Serveurs ASGI { #asgi-servers }

Allons un peu plus en détail.

FastAPI utilise un standard pour construire des frameworks web Python et des serveurs appelé <abbr title="Asynchronous Server Gateway Interface - Interface passerelle serveur asynchrone">ASGI</abbr>. FastAPI est un framework web ASGI.

Actually, all (or most) of the web frameworks work in this same way.

You never call those functions directly. They are called by your framework (in this case, **FastAPI**).

Example:

Source (English):

```
[One of the fastest Python frameworks available](#performance)
```

Result (German):

```
[Eines der schnellsten verfügbaren Python-Frameworks](#performance)
```

- For absolute URLs which DO NOT start EXACTLY with https://fastapi.tiangolo.com, only translate the link text and leave the URL unchanged.

* Data validation
* API annotation and automatic documentation

And you only have to declare them once.

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *
