* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

también puedes declarar un grupo de `examples` con información adicional que se añadirá a sus **JSON Schemas** dentro de **OpenAPI**.

### `Body` con `examples` { #body-with-examples }

Aquí pasamos `examples` que contiene un ejemplo de los datos esperados en `Body()`:
