But if we access the docs UI at the "official" URL using the proxy with port `9999`, at `/api/v1/docs`, it works correctly! 🎉

You can check it at <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="Item-Input").click()
    page.get_by_role("button", name="Item-Output").click()
    page.set_viewport_size({"width": 960, "height": 820})
    # Manually add the screenshot
    page.screenshot(
        path="docs/en/docs/img/tutorial/separate-openapi-schemas/image04.png"
    )

А вот если открыть интерфейс документации по «официальному» URL через прокси на порту `9999`, по `/api/v1/docs`, всё работает корректно! 🎉

Проверьте по адресу <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

Именно как и хотелось. ✔️

## Automatic docs { #automatic-docs }

The JSON Schemas of your models will be part of your OpenAPI generated schema, and will be shown in the interactive API docs:

And will also be used in the API docs inside each *path operation* that needs them:

### Check the docs { #check-the-docs }

Because the available values for the *path parameter* are predefined, the interactive docs can show them nicely:
