Nuevamente, haciendo solo esa declaración, con **FastAPI** obtienes:

* Soporte de editor (autocompletado, etc.), incluso para modelos anidados
* Conversión de datos
* Validación de datos
* Documentación automática

`JSONResponse` itself is a sub-class of `Response`.

And when you return a `Response`, **FastAPI** will pass it directly.

It won't do any data conversion with Pydantic models, it won't convert the contents to any type, etc.

This gives you a lot of flexibility. You can return any data type, override any data declaration or validation, etc.

 * data store specific parameters with type-safe access methods.
 *
 * <p>The class uses a ParamMap internally which provides case format conversion
 * between camelCase and snake_case parameter names for flexible parameter access.
 * Parameters can be stored as any Object type and retrieved with type conversion
 * support for common types like String.</p>
 *
 * <p>This class is commonly used to pass configuration parameters to data store

Además, nota que **FastAPI** es lo suficientemente inteligente para notar que el parámetro de path `item_id` es un parámetro de path y `q` no lo es, por lo tanto, es un parámetro de query.

///

## Conversión de tipos en parámetros de query { #query-parameter-type-conversion }

También puedes declarar tipos `bool`, y serán convertidos:

{* ../../docs_src/query_params/tutorial003_py310.py hl[7] *}

En este caso, si vas a:

```

        "name": "The Foo live"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation
