If you have a group of **query parameters** that are related, you can create a **Pydantic model** to declare them.

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

## Anotaciones de tipos con metadata

Python también tiene una funcionalidad que permite poner **<abbr title="Datos sobre los datos, en este caso, información sobre el tipo, por ejemplo, una descripción.">metadata</abbr> adicional** en estas anotaciones de tipos usando `Annotated`.
