Sua API quase sempre irá enviar um corpo na **resposta**. Mas os clientes não necessariamente precisam enviar um corpo em toda **requisição**.

Para declarar um corpo da **requisição**, você utiliza os modelos do <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> com todos os seus poderes e benefícios.
