It is a project from the Linux Foundation. It provides **HTTPS certificates for free**, in an automated way. These certificates use all the standard cryptographic security, and are short-lived (about 3 months), so the **security is actually better** because of their reduced lifespan.

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

### Detalles Técnicos: `root_path` { #technical-details-root-path }

Cuando montas una sub-aplicación como se describe arriba, FastAPI se encargará de comunicar el path de montaje para la sub-aplicación usando un mecanismo de la especificación ASGI llamado `root_path`.
