Kling O3 API 레퍼런스

올인원 Kling: 생성·애니메이션·레퍼런스·편집을 최대 4K로

PopNow API 키 하나로 내 코드에서 Kling O3을(를) 호출할 수 있습니다. 보낼 모델 ID, 이 모델이 받는 모든 입력 필드, 요청 한 번에 드는 크레딧, 터미널에 붙여 넣으면 바로 실행되는 요청을 정리했습니다.

파라미터 설명은 모델의 입력 schema에서 가져오므로 영어로만 제공됩니다.

1크레딧 = 0.01달러. 작업이 접수되면 가능한 최대 금액을 먼저 잡아 두고, 끝나면 실제 사용량으로 정산합니다(정수 크레딧으로 올림, 남는 금액은 반환). 실패한 작업에는 과금하지 않습니다. 실행 전에 정확한 금액이 궁금하면 POST /api/v1/jobs/quote를 호출하세요.
