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

</div>

Потім, якщо ви перейдете за URL `/openapi.json`, `/docs` або `/redoc`, ви просто отримаєте помилку `404 Not Found` на кшталт:

```JSON
{
    "detail": "Not Found"
}

而且因為產生的 schema 來自 [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) 標準，有很多相容的工具可用。

因此，**FastAPI** 本身也提供另一種 API 文件（使用 ReDoc），你可以在 [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) 存取：

同樣地，也有許多相容工具可用，包括支援多種語言的程式碼產生工具。
