Pricing

Billed by token (word-for-word identical to the upstream official terms): video price = per-token price × tokens used.

Rates: per second480p40.352Credits720p90.72Credits1080p224.532Credits
Settlement: Submission holds the worst case up front (the largest-pixel aspect ratio at this resolution + reference video at the full limit) → settled at actual usage on completion → the difference is refunded

Token usage = (input video duration + output video duration) × output video width × height × frame rate ÷ 1024, with the frame rate fixed at 24; width and height come from the pixel table in the official "Create video generation task" docs (by resolution × aspect ratio), and the usage.completion_tokens returned by the upstream is authoritative.
Minimum usage: when the input includes video, input video duration is counted from 4 seconds, so a 2-second reference video costs the same as a 4-second one. The official cap on total reference video duration is 30 seconds.
Token pricing (points / million tokens): Input has no video 4200 · Input has no video · 1080p delivery 4620 · Input includes video 2520 · Input includes video · 1080p delivery 2760.
Failed or expired tasks are refunded in full.
Polling task status is free and does not count toward usage.
All your API keys share one balance; when it runs out the API returns HTTP 402 `quota_exceeded`.
