O **FastAPI** **extrairá** os dados para **cada campo** dos **parâmetros de consulta** presentes na requisição, e fornecerá o modelo Pydantic que você definiu.


## Verifique os Documentos

Você pode ver os parâmetros de consulta nos documentos de IU em `/docs`:

    int NT_STATUS_LOGON_TYPE_NOT_GRANTED = 0xC000015b;
    /** The SAM database does not have a computer account for this workstation trust relationship */

  This way you can make sure you're not wasting your time on something that isn't

+ Submit a ticket for your issue, assuming one does not already exist.
  + Clearly describe the issue, including steps to reproduce when it is a bug.
  + Make sure you fill in the earliest version that you know has the issue.
+ Fork the repository on GitHub.

Declare uma variável com a mesma sintaxe com dois pontos (`:`)

Como tipo, coloque o `List` que você importou de `typing`.

Como a lista é o tipo que contém algum tipo interno, você coloca o tipo dentro de colchetes:

```Python hl_lines="4"
