Ship AI video features without wrestling with upstream providers. The Seedance 2.0 API gives you text-to-video, image-to-video, reference-to-video, and video extension from a single REST endpoint. Free credits on signup, pay per second after.
ByteDance ships Seedance 2.0 with four generation modes — text-to-video, image-to-video, omni-reference, and video extension. Most upstream providers make you hit a different route for each. The Seedance 2.0 API on our platform uses one endpoint for all four.
Send a prompt for text-to-video. Add an input image for image-to-video. Layer reference photos for character and scene control. Attach a previous clip to extend it. The Seedance 2.0 API reads your payload and routes to the right mode automatically. No switching SDK methods, no juggling separate auth tokens, no reading four sets of docs. Integrate the Seedance 2.0 API once and pick the mode at request time.
The raw Seedance 2.0 API from upstream providers is async — submit a job, poll for the result, retry on timeout, handle webhooks. That is boilerplate you have to write before your app does anything useful.
Our wrapper around the Seedance 2.0 API handles the poll loop, retries on timeout, and returns the final video URL on a clean REST response. Every Seedance 2.0 API request is SSRF-checked before it touches upstream infrastructure — we reject private IPs, localhost, and malformed URLs so end users cannot turn your key into a reverse proxy. Errors come back as structured JSON with a stable code, not a plain text 500.
The Seedance 2.0 API is credit-based. A 5-second 720p clip costs the same whether you render one per day or a thousand. No monthly commitment, no idle seat fees, no separate billing for each Seedance 2.0 API generation mode.
New accounts start with free credits — enough to ship a working prototype before you pay. After that, buy credits in $10 increments or grab a monthly plan. Seedance 2.0 API calls land cheaper than Sora 2 or Veo 3 at the same resolution, and the same credits work across every video model we host. One Seedance 2.0 API key doubles as your key for all of them.
One key unlocks more than Seedance. The same REST endpoint that runs the Seedance 2.0 API also calls Sora 2, Veo 3, Kling V3, and the other video models we host. Compare outputs across models by flipping a single parameter.
Most teams end up using more than one video model in production. Seedance handles cinematic and stylized prompts well. Veo 3 is strong on realistic human motion. Sora 2 leans toward surreal scenes. Testing which fits your product usually means integrating three SDKs. Here you write the Seedance 2.0 API integration once, then route prompts to different models by changing the model field.
The Seedance 2.0 API is a REST wrapper around ByteDance's Seedance 2.0 video model, built for developers who want production video generation without managing upstream provider accounts, polling loops, or error translation. Here is what the Seedance 2.0 API unlocks on signup.
POST a prompt to the Seedance 2.0 API and get a rendered clip back. Realistic, anime, product, and cinematic styles. Up to 1080p HD, 4 to 10 seconds per call.
Upload a still image with your request. The Seedance 2.0 API animates it — portraits gain natural head motion, products spin, landscapes pick up wind and water movement.
Attach reference images for character, scene, or style. The Seedance 2.0 API blends them with your prompt so output matches the look you wanted, not a random interpretation.
Pass an existing clip and a continuation prompt. The Seedance 2.0 API picks up from the final frame and keeps the motion going — same character, same scene, same direction.
Create a key in the dashboard and attach it as a Bearer token. New accounts get free credits so you can run the Seedance 2.0 API end-to-end before paying anything.
The same Bearer token also works for Sora 2, Veo 3, Kling V3, and every other video model we host. Switch by changing one field in your Seedance 2.0 API request.
Three steps from signup to shipped video.
Sign up, open the API Keys page, and generate a Bearer token. Free credits land in your account automatically — no credit card needed to start calling the Seedance 2.0 API.
Send a JSON body to the Seedance 2.0 API with your model, prompt, and any reference files. Pick text-to-video, image-to-video, omni-reference, or video extension by including the matching inputs.
Hit the task endpoint with the returned task ID. The Seedance 2.0 API returns a ready video URL once rendering completes — usually under a minute for a 5-second 720p clip.
