In those cases, you can use the *path operation decorator* parameter `response_model` instead of the return type.

You can use the `response_model` parameter in any of the *path operations*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

La simplicidad del sistema de inyección de dependencias hace que **FastAPI** sea compatible con:

* todas las bases de datos relacionales
* bases de datos NoSQL
* paquetes externos
* APIs externas
* sistemas de autenticación y autorización
* sistemas de monitoreo de uso de la API
* sistemas de inyección de datos de response
* etc.
