关键验证结果

​
模型命名

  • 顶层 model 必须是 wan22-video-generation（不是 seedance-20 也不是 seedance20-video-generation）
  • inputs.model 必须是 seedance-20
  • 状态查询返回的 model 字段是 seedance20-video-generation（这是内部 toolId）

​
Credits 计费

  • keyframe 模式: 40 credits/秒 (5s=200, 10s=400)
  • reference 模式: 90 credits/秒 (5s=450)

​
合法 Resolution

  • 720x720 (1:1)
  • 720x960 (3:4)
  • 960x720 (4:3)
  • 1280x720 (16:9)
  • 720x1280 (9:16)

​
任务状态流转

  • waiting → generating → success (含 output URL) / fail (含 error)
