## FastAPIの機能 { #fastapi-features }

**FastAPI** は次のものを提供します:

### オープンスタンダード準拠 { #based-on-open-standards }

* API 作成のための [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification)。<dfn title="別名: エンドポイント、ルート">パス</dfn> <dfn title="別名: HTTP メソッド（POST、GET、PUT、DELETE など）">オペレーション</dfn>、パラメータ、リクエストボディ、セキュリティなどの宣言を含みます。
* [**JSON Schema**](https://json-schema.org/) によるデータモデルの自動ドキュメント化（OpenAPI 自体が JSON Schema に基づいています）。

					time.Sleep(100*time.Millisecond + time.Duration(r.Float64()*float64(time.Second)))
					continue
