O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.

O `Union` em `Union[str, None]` não é utilizado pelo FastAPI, mas permite ao seu editor de texto lhe dar um suporte melhor e detectar erros.

Importa `BaseSettings` de Pydantic y crea una sub-clase, muy similar a un modelo de Pydantic.

De la misma forma que con los modelos de Pydantic, declaras atributos de clase con anotaciones de tipos, y posiblemente, valores por defecto.

Puedes usar todas las mismas funcionalidades de validación y herramientas que usas para los modelos de Pydantic, como diferentes tipos de datos y validaciones adicionales con `Field()`.

Usar `UploadFile` tiene varias ventajas sobre `bytes`:

* No tienes que usar `File()` en el valor por defecto del parámetro.
* Usa un archivo "spooled":
    * Un archivo almacenado en memoria hasta un límite de tamaño máximo, y después de superar este límite, se almacenará en el disco.
