Seedance 2.5 API: 3% Below List Price, Pay-as-you-go, No Prepaid Pack (2026)
Official Seedance 2.5 channels never discount and BytePlus requires a $30.10 non-refundable prepaid pack. cocodot bills the same model at 97% of list price, pay-as-you-go via Alipay or card. A 5-second 480p video runs about $0.46.
Why teams want the Seedance 2.5 API
Seedance 2.5 is the current flagship for AI short-drama and ad-creative pipelines: native 30-second generation, multi-reference input (image/audio/video), local editing. The consumer apps (Jimeng/Dreamina) are subscription + credits — fine for hobbyists, nowhere near enough for production volume. Production teams need metered API access.
The real friction in official channels
Volcano Engine (China) bills at full list price and never discounts. BytePlus (international) adds a minimum $30.10 prepaid resource pack — non-refundable, expires in 90 days — plus KYC review. Before you have generated a single test clip, you have already committed money and paperwork.
cocodot: 97% of list, metered, no gate
We buy Seedance capacity at channel rates and pass part of the margin on: **every tier at 97% of official list price** (table above). No prepaid pack, no minimum top-up, balance never expires. Top up with Alipay or card. Note: the $0.5 signup credit is API-text only — video needs a real balance.
What a clip actually costs: the token formula
Seedance bills per token: **tokens = width x height x fps x seconds / 1024** (24fps). Examples: 5s 480p ~ 48k tokens ~ ¥3.26; 5s 720p ~ 108k tokens ~ ¥7.33; 5s 1080p ~ 243k tokens ~ ¥18.15. Our measured 4-second 480p run consumed 38,830 tokens (1% off the formula) — about ¥2.6 at our rate. You can verify the whole pipeline for under a dollar before scaling.
Three steps: submit, poll, download
Generation is async. 1) Submit: POST https://cocodot.co/api/ai/video/generations with model "seedance-2.5", resolution 480p/720p/1080p, and a content array holding your text prompt (plus optional image/video references); returns a task id. 2) Poll: GET /api/ai/video/generations/{id} until status is SUCCEEDED; the response carries the video URL (upstream links expire — save promptly). 3) Billing: you are charged only when a task succeeds; failures cost nothing, and the unit price is locked at submission time.
480p or 1080p: an honest cost note
Real short-drama workflows draw 8-15 generations per usable shot. Do the volume drafting at 480p (~¥3.26 per clip, metered, unlimited), then re-render selected shots at 1080p for final cut. Drafting everything at 1080p burns money on any channel — that is a workflow issue, not a vendor issue.
