	Não importa o que você digita no formulário, não vai funcionar ainda. Mas nós vamos chegar lá.

Claro que este não é o frontend para os usuários finais, mas é uma ótima ferramenta automática para documentar interativamente toda sua API.

Pode ser usado pelo time de frontend (que pode ser você no caso).

Pode ser usado por aplicações e sistemas third party (de terceiros).

It was one of the first examples of **automatic API documentation**, and this was specifically one of the first ideas that inspired "the search for" **FastAPI**.

/// note

Django REST Framework was created by Tom Christie. The same creator of Starlette and Uvicorn, on which **FastAPI** is based.

///

/// check | "Inspired **FastAPI** to"

Have an automatic API documentation web user interface.

///

///

/// info

To declare headers, you need to use `Header`, because otherwise the parameters would be interpreted as query parameters.

///

## Automatic conversion

`Header` has a little extra functionality on top of what `Path`, `Query` and `Cookie` provide.

Most of the standard headers are separated by a "hyphen" character, also known as the "minus symbol" (`-`).

///

O **FastAPI** fará a conversão automática a partir da requisição, assim esse parâmetro `item` receberá seu respectivo conteúdo e o mesmo ocorrerá com `user`.

Ele executará a validação dos dados compostos e irá documentá-los de maneira compatível com o esquema OpenAPI e documentação automática.

## Valores singulares no corpo

Die Verwendung in Ihrem eigenen Editor zeigt Ihnen die Vorteile von FastAPI am besten, wenn Sie sehen, wie wenig Code Sie schreiben müssen, all die Typprüfungen, die automatische Vervollständigung usw.

---

## FastAPI installieren

Der erste Schritt besteht aus der Installation von FastAPI.

* **Data te converteren**: van de request naar het vereiste type.
* **Data te valideren**: afkomstig van elke request:
    * **Automatische foutmeldingen** te genereren die naar de client worden geretourneerd wanneer de data ongeldig is.
* De API met OpenAPI te **documenteren**:
    * die vervolgens wordt gebruikt door de automatische interactieve documentatie gebruikersinterfaces.

Und Sie haben immer noch dieselbe Funktionalität wie bisher gesehen:

* Großartige Editor-Unterstützung.
* Datenkonvertierung bei eingehenden Requests.
* Datenkonvertierung für Response-Daten.
* Datenvalidierung.
* Automatische Annotation und Dokumentation.

## Andere Datentypen

Hier sind einige der zusätzlichen Datentypen, die Sie verwenden können:

* `UUID`:

## OpenAPI

OpenAPI (previously known as Swagger) is the open specification for building APIs (now part of the Linux Foundation).

**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

OpenAPI has a way to define multiple security "schemes".
