Para lograr esto, puedes usar la opción de línea de comandos `--root-path` como:

<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>

Si usas Hypercorn, también tiene la opción `--root-path`.
