Pricing

Billed per token, exactly as the upstream bills it: video price = token price × tokens used.

Rates: per second720p47.693Credits1080p118.973Credits
Settlement: On submit, the worst case is held (the largest frame at that resolution + reference video at its limit) → settled on actual usage when done → the difference is refunded

Token usage = (input video seconds + output video seconds) × output width × height × frame rate ÷ 1024, at a fixed 24 fps. Width and height come from the official pixel table for video generation tasks (by resolution × aspect ratio); the usage.completion_tokens the upstream returns is what counts.
Minimum usage: when the input includes video, input video counts as at least 4 seconds — a 2-second reference video costs the same as a 4-second one. The official limit for total reference video is 15 seconds.
Token price (credits per 1M tokens): without input video · 1080p output 2448 · without input video · 720p output 2208 · with input video · 1080p output 1488 · with input video · 720p output 1344.
This card is priced by output resolution: resolution is required (720p or 1080p only); leaving it out returns 400.
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`.

Seedance 2.0 Lite FAQ

How do I call Seedance 2.0 Lite?

Set the model field of the request body to doubao-seedance-2.0-lite, send it to https://api.dflop.top/v1/videos/generations, and put your key (it starts with sk-gpushare-) in the Authorization: Bearer header. This is not a chat SKU; submit tasks to the dedicated endpoint above.

How much does the Seedance 2.0 Lite API cost?

Billing: per token (the same formula as the upstream's official one). Video price = token price × tokens used; tokens used = (input video length + output video length) × output width × height × frame rate ÷ 1024, with the frame rate fixed at 24, as reported in the upstream's usage.completion_tokens
Token price (without input video · 1080p output): 3,060 credits (≈ ¥51 / ≈ $7.57) per 1M tokens
Token price (without input video · 720p output): 2,760 credits (≈ ¥46 / ≈ $6.82) per 1M tokens
Token price (with input video · 1080p output): 1,860 credits (≈ ¥31 / ≈ $4.6) per 1M tokens
Token price (with input video · 720p output): 1,680 credits (≈ ¥28 / ≈ $4.15) per 1M tokens
For reference (16:9, no input video): 720p about 59.62 / 1080p about 148.72 credits per second of output
Prices are in credits: 60 credits = ¥1. Each call first holds the most it could cost, then settles on actual usage and refunds the difference.
