* OpenAPI *경로 처리*의 응답에 **JSON Schema**를 추가합니다.
    * 이는 **자동 문서**에서 사용됩니다.
    * 또한 자동 클라이언트 코드 생성 도구에서도 사용됩니다.
* 반환된 데이터를 Pydantic을 사용해 JSON으로 **직렬화**합니다. Pydantic은 **Rust**로 작성되어 있어 **훨씬 더 빠릅니다**.

하지만 가장 중요한 것은:

* 반환 타입에 정의된 내용으로 출력 데이터를 **제한하고 필터링**합니다.
    * 이는 특히 **보안**에 매우 중요합니다. 아래에서 더 자세히 살펴보겠습니다.
