Aquí tienes un ejemplo de cómo podría ser una API HTTPS, paso a paso, prestando atención principalmente a las ideas importantes para los desarrolladores.

### Nombre de Dominio { #domain-name }

Probablemente todo comenzaría adquiriendo un **nombre de dominio**. Luego, lo configurarías en un servidor DNS (posiblemente tu mismo proveedor de la nube).

코드 어디에도 평문 패스워드 "`secret`"은 없고, 해시된 버전만 있다는 점에 유의하십시오.

    * Zahlen (`int`, `float`) mit Mindest- und Maximalwerten, usw.

* Validierung für mehr exotische Typen, wie:
    * URL.
    * E-Mail.
    * UUID.
    * ... und andere.

Die gesamte Validierung übernimmt das gut etablierte und robuste **Pydantic**.
