## 표준 기반의 이점, 대체 문서 { #standards-based-benefits-alternative-documentation }

그리고 생성된 스키마는 [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) 표준에서 나온 것이기 때문에 호환되는 도구가 많이 있습니다.

이 덕분에 **FastAPI** 자체에서 [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc)로 접속할 수 있는 (ReDoc을 사용하는) 대체 API 문서를 제공합니다:
