Para conseguir isso, você pode usar a opção de linha de comando `--root-path` assim:

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

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

</div>

Se você usar Hypercorn, ele também tem a opção `--root-path`.
