Usarlo en tu editor es lo que realmente te muestra los beneficios de FastAPI, al ver cuán poco código tienes que escribir, todos los chequeos de tipos, autocompletado, etc.

## Instalar FastAPI

El primer paso es instalar FastAPI.

Então, dessa forma você provavelmente terá um código mais limpo.

### Validación

* Validación para la mayoría (¿o todas?) de los **tipos de datos** de Python, incluyendo:
    * Objetos JSON (`dict`).
    * Array JSON (`list`) definiendo tipos de elementos.
    * Campos de cadena de caracteres (`str`), definiendo longitudes mínimas y máximas.
    * Números (`int`, `float`) con valores mínimos y máximos, etc.

* Validación para tipos más exóticos, como:
    * URL.
    * Email.
    * UUID.

 *  Fix: Don't resolve DNS addresses when connecting through a SOCKS proxy.
