There is no official Seedance 2.1 API yet — ByteDance hasn't released the 2.1 model, let alone a developer endpoint for it. So if you're searching for "Seedance 2.1 API" or its pricing, the practical answer is about the model it currently maps to (Seedance 2) and what that costs. Here's the real picture, with numbers, and what to expect when a native 2.1 API arrives.
TL;DR
- No native Seedance 2.1 API exists as of June 2026. ByteDance hasn't shipped 2.1 or a 2.1 endpoint.
- To use Seedance programmatically today, third-party platforms (such as fal and Segmind) expose Seedance 2.0 APIs; a native 2.1 API is expected to follow the model's launch.
- To just generate without code, the seedance-21.app generator runs the Seedance 2.1 option on Seedance 2, billed in credits with the cost shown before each run.
- Cost: ~300 credits (~$2.85) for a 5-second 720p text-to-video clip; ~150 (~$1.42) for image-to-video. Cheapest pack: $29.90 → 3,150 credits.
Is there a Seedance 2.1 API?
Not officially. ByteDance has not released Seedance 2.1 or a developer API for it. Any service advertising a "Seedance 2.1 API" right now is either routing to Seedance 2.0 under that label or pre-announcing something unconfirmed. When ByteDance ships 2.1, expect a native API to roll out the way Seedance 2.0's did — first on ByteDance's own platforms and BytePlus/ModelArk, then across third-party providers.
What you can do today, programmatically, is call Seedance 2.0, which is live. Platforms like fal and Segmind host it with usage-based pricing. That's the closest thing to a "Seedance 2.1 API" until the real one exists — same family, current generation.
Seedance 2.1 pricing — what it actually costs
On seedance-21.app, you don't need an API key to generate; the web generator bills in credits from a single pool shared across every video and image model, and previews the cost before each run. For the Seedance 2.1 option (running on Seedance 2):
| Output (5s, 720p) | Credits | ≈ USD* |
|---|---|---|
| Text-to-video — Seedance 2.1 / 2 | ~300 | ~$2.85 |
| Image-to-video — Seedance 2.1 / 2 | ~150 | ~$1.42 |
| Text-to-video — Fast / 2.0 Mini | ~210 | ~$1.99 |
| Image-to-video — Fast / 2.0 Mini | ~105 | ~$1.00 |
*USD estimated at the Starter pack rate. Credit cost scales with resolution, duration, and audio.
Credit packs: Starter $29.90 → 3,150 credits, Creator $59.90 → 7,200, Studio $99.90 → 13,200. New accounts start with free credits, and there's no charge for failed generations. Full tiers live on the pricing page.
How the billing works (the part most pages skip)
Credits are deducted only on success, and the amount depends on the model, resolution, duration, and whether you add audio — not a flat per-clip fee. That means a 480p 5-second draft is cheap, and a 1080p clip with audio costs several times more. Because the generator shows the exact credit cost before you confirm, you always see the price before spending. For programmatic Seedance 2.0 via third-party APIs, pricing is typically per second of output at each resolution tier — check the provider's current rates, as they change.
What to expect from a native 2.1 API
When Seedance 2.1 launches, a developer API will most likely appear with per-second pricing by resolution, similar to how Seedance 2.0 is sold on fal and Segmind today. Whether 2.1 costs more than 2.0 will depend on ByteDance's pricing — preview coverage suggests a quality bump (~20% over 2.0) and a cheaper Mini tier, but nothing about API rates is confirmed. We'll update this page when there's an official endpoint and price.
