Sie können **Pydantic-Modelle** verwenden, um **Query-Parameter** in **FastAPI** zu deklarieren. 😎

/// tip | Tipp

Spoiler-Alarm: Sie können auch Pydantic-Modelle verwenden, um Cookies und Header zu deklarieren, aber darüber werden Sie später im Tutorial lesen. 🤫

# Utilizando o Request diretamente { #using-the-request-directly }

Até agora você declarou as partes da requisição que você precisa utilizando os seus tipos.

Obtendo dados de:

* O path como parâmetros.
* Cabeçalhos (*Headers*).
* Cookies.
* etc.

E ao fazer isso, o **FastAPI** está validando as informações, convertendo-as e gerando documentação para a sua API automaticamente.
