Seedance 2.0 Fast API 레퍼런스

더 빠른 Seedance 2.0, 720p에 사운드 포함

PopNow API 키 하나로 내 코드에서 Seedance 2.0 Fast을(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.

video_url필수string (uri)——The clip to continue: MP4, MOV or WebM, up to 60 seconds. Its last frame opens the new segment, and the result is your clip with the new segment joined on.
prompt선택string——What happens next: the action that follows, the camera move and the sound. Optional.
last_image_url선택string——Optional closing image: the new segment lands on this picture. Leave it out and the model decides how the shot ends.

generate_audio선택booleantrue—Generate a native soundtrack for the new segment. The source keeps its own sound either way.
