works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an

Aquí veremos un ejemplo usando [SQLModel](https://sqlmodel.tiangolo.com/).

**SQLModel** está construido sobre [SQLAlchemy](https://www.sqlalchemy.org/) y Pydantic. Fue creado por el mismo autor de **FastAPI** para ser la combinación perfecta para aplicaciones de FastAPI que necesiten usar **bases de datos SQL**.

Esta última path operation tendrá la combinación de tags: `["items", "custom"]`.

Y también tendrá ambas responses en la documentación, una para `404` y otra para `403`.
