Tips

  • mode is fixed to standard for public API usage.
  • image_urls and video_urls each require exactly one URL.
  • resolution defaults to 480p; choose 720p when quality is more important than cost.
  • Billing is duration-based with limits: below 5s is billed as 5s, above 120s is billed as 120s.
  • Use seed to improve reproducibility across repeated runs.
Wan 2.2 Animate API pricing is per second with a 5-second minimum billable duration and 120-second maximum billable duration.
