### Check the automatic API docs { #check-the-automatic-api-docs }

Now, run the `fastapi` command with your file:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

And open the docs at <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

# Моделі форм (Form Models)

У FastAPI Ви можете використовувати **Pydantic-моделі** для оголошення **полів форми**.

/// info | Інформація

Щоб використовувати форми, спочатку встановіть <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">python-multipart</a>.

C'est un outil formidable et je l'ai beaucoup utilisé aussi, avant d'avoir **FastAPI**.
