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.

Lembre-se de que dataclasses não podem fazer tudo o que os modelos Pydantic podem fazer.

Então, você ainda pode precisar usar modelos Pydantic.

Mas se você tem um monte de dataclasses por aí, este é um truque legal para usá-las para alimentar uma API web usando FastAPI. 🤓

## FastAPI People PRs

Every month, a GitHub Action updates the FastAPI People data. Those PRs look like this one: [👥 Update FastAPI People](https://github.com/fastapi/fastapi/pull/11669).

If the tests are passing, you can merge it right away.

  `You'll get used to it in time,' said the Caterpillar; and it
put the hookah into its mouth and began smoking again.

  This time Alice waited patiently until it chose to speak again.
In a minute or two the Caterpillar took the hookah out of its
mouth and yawned once or twice, and shook itself.  Then it got
down off the mushroom, and crawled away in the grass, merely

Então, para equilibrar tudo, imagine a seguinte historinha:
