そのステータスコードはレスポンスで使用され、OpenAPIスキーマに追加されます。

/// note | "技術詳細"

また、`from starlette import status`を使用することもできます。

**FastAPI** は開発者の利便性を考慮して、`fastapi.status`と同じ`starlette.status`を提供しています。しかし、これはStarletteから直接提供されています。

## タグ

`tags`パラメータを`str`の`list`（通常は１つの`str`）と一緒に渡すと、*path operation*にタグを追加できます:

```Python hl_lines="17  22  27"

from fastapi import FastAPI, Query
from typing_extensions import Annotated

app = FastAPI()


@app.get("/items/")
async def read_items(q: Annotated[str, Query(min_length=3)] = "fixedquery"):
