Seedance API: How to Access It (and a No-Code Alternative)
Where to get the Seedance API — ByteDance's official Volcano Engine / BytePlus endpoint plus authorized partners like fal and Replicate — how billing works, and a no-code way to skip it.
Yes, Seedance has an API — in fact several ways to reach it. Here's the difference between the official endpoint and the partner platforms, roughly what it costs, and a no-code option if you'd rather not manage keys and billing at all.
The official API (ByteDance)
Seedance's first-party API is served through ByteDance's own cloud:
- Volcano Engine Ark (火山方舟) for China, and BytePlus ModelArk internationally.
- Base URL along the lines of
https://ark.cn-beijing.volces.com/api/v3, with an official Python SDK (volcengine-python-sdk[ark]). - Models are listed under the
doubao-seedance-*family — e.g.doubao-seedance-1.0-pro(text-to-video and image-to-video, 480p/720p/1080p at 24fps, 2–12s clips).
Because model IDs for newer versions get updated, check the current provider docs for the exact Seedance 2.0 / 2.5 model identifier rather than copying one from a blog.
Authorized partner providers
If you want a simpler REST interface or you're already on another stack, ByteDance's authorized partners also serve Seedance:
- fal.ai — an official partner, with endpoints such as
fal-ai/bytedance/seedance/v1/pro/image-to-videoand Seedance 2.0text-to-video/image-to-video/reference-to-video. - Replicate —
bytedance/seedance-2.0and a lighterbytedance/seedance-2.0-mini. - sunra.ai, Pollo AI, and others also expose Seedance models.
A word of caution: many smaller "Seedance API" gateways are resellers routing to one of the above, not official integrations. Prefer first-party or clearly authorized partners for reliability and terms.
How API billing works
Two models dominate (covered in more depth in Seedance 2.0 pricing):
- Per video-token on ByteDance's own API — token count scales with resolution × fps × duration.
- Per second on most Western providers (fal, Replicate) — roughly $0.08–0.30/sec at 480p–720p, more at higher resolution or with video reference inputs.
All rates move over time, so treat any number as approximate and confirm it live.
The no-code alternative
An API only makes sense if you're building software. If you just want great Seedance clips — no keys, no SDK, no per-provider billing to manage — you can skip the API entirely:
- Start from a tested prompt in the library.
- Generate it on ponpon, which runs the Seedance model line for you.
And if you were hoping to self-host to avoid API costs, read is Seedance open source first — the short answer changes the math.
