Puedes declarar un response que sea la `Union` de dos o más tipos, eso significa que el response sería cualquiera de ellos.

Se definirá en OpenAPI con `anyOf`.

Para hacerlo, usa la anotación de tipos estándar de Python [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

/// note | Nota

import org.gradle.api.DefaultTask;
import org.gradle.api.GradleException;
import org.gradle.api.file.DirectoryProperty;
import org.gradle.api.file.RegularFileProperty;
import org.gradle.api.tasks.CacheableTask;

Other HTTP libraries exist that fill that gap allowing extensive customisation including potentially
invalid requests.

Example Limitations

* Does not allow GET with a body.
* Cache is not an interface with alternative implementations.

Get a URL
---------

This program downloads a URL and prints its contents as a string. [Full source][get_example].

```java

De esta manera, puedes obtener lo mejor de ambos mundos: anotaciones de tipos con **soporte de herramientas** y **filtrado de datos**.

Cuando veas la documentación automática, puedes verificar que el modelo de entrada y el modelo de salida tendrán cada uno su propio JSON Schema:
