Continuemos con el ejemplo anterior. Queríamos **anotar la función con un tipo**, pero queríamos poder devolver desde la función algo que en realidad incluya **más datos**.

Queremos que FastAPI continúe **filtrando** los datos usando el modelo de response. Para que, incluso cuando la función devuelva más datos, el response solo incluya los campos declarados en el modelo de response.

Ao invés disso, sendo um sistema "assíncrono", uma vez finalizada, a tarefa pode esperar na fila um pouco (alguns microssegundos) para que o computador / programa finalize o que quer que esteja fazendo, e então volte para pegar o resultado e continue trabalhando com ele.
