## Instalasi

Buat dan aktifkan <a href="https://fastapi.tiangolo.com/virtual-environments/" class="external-link" target="_blank">virtual environment</a> kemudian *install* FastAPI:

También puedes declarar responses adicionales con sus modelos, códigos de estado, etc.

Hay un capítulo entero en la documentación sobre ello, puedes leerlo en [Responses Adicionales en OpenAPI](additional-responses.md){.internal-link target=_blank}.

## OpenAPI Extra

Cuando declaras una *path operation* en tu aplicación, **FastAPI** genera automáticamente los metadatos relevantes sobre esa *path operation* para incluirlos en el esquema de OpenAPI.

Para hacerlo, usa el type hint estándar de Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

                    }
                } else if (links == Dfs.FALSE_ENTRY) {
                    links = null;
                }

                if (links != null) {
