## License

But by using `Security` instead of `Depends`, **FastAPI** will know that it can declare security scopes, use them internally, and document the API with OpenAPI.

But when you import `Query`, `Path`, `Depends`, `Security` and others from `fastapi`, those are actually functions that return special classes.

///

## Use `SecurityScopes` { #use-securityscopes }

## Beneficios { #benefits }

Cuando uses los clientes generados automáticamente obtendrás **autocompletado** para:

* Métodos.
* Payloads de request en el body, parámetros de query, etc.
* Payloads de response.

También tendrás **errores en línea** para todo.
