그리고 `/openapi.json`, `/docs` 또는 `/redoc`의 URL로 이동하면 `404 Not Found`라는 오류가 다음과 같이 표시됩니다:

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

    if x_token != fake_secret_token:
        raise HTTPException(status_code=400, detail="Invalid X-Token header")
    if item_id not in fake_db:
        raise HTTPException(status_code=404, detail="Item not found")
    return fake_db[item_id]


@app.post("/items/", response_model=Item)
async def create_item(item: Item, x_token: Annotated[str, Header()]):

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

</div>

Então, se você acessar as URLs em `/openapi.json`, `/docs` ou `/redoc`, você receberá apenas um erro `404 Not Found` como:

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