Las claves del `dict` identifican cada ejemplo, y cada valor es otro `dict`.

Cada `dict` específico del ejemplo en los `examples` puede contener:

* `summary`: Descripción corta del ejemplo.
* `description`: Una descripción larga que puede contener texto Markdown.
* `value`: Este es el ejemplo real mostrado, e.g. un `dict`.

You can return it directly.

It accepts the following parameters:

* `content` - A `str` or `bytes`.
* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.

* `allow_credentials` - Indica que...

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

Because **FastAPI** doesn't make any changes to a `Response` you return, you have to make sure its contents are ready for it.
