How does Seedance 2.0 API pricing work?

Credit-based — 1 credit equals $0.001. The Seedance 2.0 cost scales with output duration × resolution × reference mode. Text-to-video runs slightly more than reference-driven generation. The Seedance 2.0 estimator on this page models any setting before you submit.

Which Seedance 2.0 variant should I pick?

Standard for general use. Fast variants for cheaper, lower-resolution drafts — no 1080p. Face variants when you upload real-person references; the standard variants reject real people. Fast-face combines both Seedance 2.0 acceleration tricks.

Can the Seedance 2.0 API animate a still image?

Yes. Pass image URLs in image_urls and Seedance 2.0 switches to image-to-video. The first image becomes the first frame; the prompt drives the motion. Up to nine reference images per request.

Does Seedance 2.0 generate audio?

Yes. Set generate_audio to true and Seedance 2.0 synthesizes an audio track that plays with the video. Pass audio_urls to drive lip-sync — available on the Seedance 2.0 face and fast-face variants.

How fast is Seedance 2.0 generation?

Most jobs finish in 1 to 5 minutes. Fast variants run roughly 2× quicker than standard. The worker's wall-clock cap is 48 hours, so even queued Seedance 2.0 jobs never time out silently.

Where is the full Seedance 2.0 API reference?

The complete Seedance 2.0 API parameter list, error codes, and runnable cURL examples live at /docs/seedance-2-0.

Is Seedance 2.0 free or paid?

Paid. Completed generations are charged at the rates in this page's pricing table. Eligible new accounts may receive promotional test credits; availability and amount are shown at signup or in the dashboard. Technical or provider failures are refunded automatically, except where this page documents a charged output-moderation block.

Does Seedance 2.0 require a monthly subscription?

No. Pricing is pay-as-you-go: $1 buys 1,000 credits and credits never expire. Cost scales with what you generate rather than with a recurring fee.

How do I get a Seedance 2.0 API key?

Sign up and create a key in the dashboard, no card required. Pass it as a Bearer token in the Authorization header.

What is the Seedance 2.0 API?

Seedance 2.0 is ByteDance's video generation model, exposed on reAPI as one async endpoint where the mode is implicit: the media fields you send decide whether the request runs as text-to-video, image-to-video, a first/last-frame transition, or reference-driven generation from up to nine images, three video clips and three audio tracks. Each request returns 4–15 seconds of video at 480p, 720p, 1080p or 4K, with optional generated audio. Billing is per second of actual output.

What you can build with this model

Real-world workflows and production use cases you can build and ship with this model.

Spin up product demos with the Seedance 2.0 API

Send one product photo to the Seedance 2.0 API and get a hero shot, pan, or zoom video back in minutes. Iterate on cuts at the speed of prompts — no film crew, no storyboard, no edit timeline.

Generate a clip

Bring stills to life as social videos

Pass a static image with a motion prompt. Seedance 2.0 returns a 4–15 second clip ready for Reels, Shorts, and TikTok. Skip the storyboard, ship the post.

Lip-sync real people with the Face variants

Combine reference video and audio with Seedance 2.0 face or fast-face to animate real people speaking. One Seedance 2.0 API call covers voiceovers, explainers, and character animation.
