Apenas com esse declaração de tipos do Python, o **FastAPI** irá:

* Ler o corpo da requisição como um JSON.
* Converter os tipos correspondentes (se necessário).
* Validar os dados.
    * Se algum dados for inválido, irá retornar um erro bem claro, indicando exatamente onde e o que está incorreto.
* Entregar a você a informação recebida no parâmetro `item`.
