Seedance 2.5 API
You send a prompt to one REST endpoint and the Seedance 2.5 API sends back a 5 second 16:9 clip with sound.
You can open and change this workflow for free, and new accounts get a free video.

How to Use Seedance 2.5 API
Steps to get you started in Wireflow.
Design the video workflow
On the visual canvas, connect a text input to an image generator and a Seedance video node. Configure aspect ratio, reference image, and audio, then save the workflow.
Call it from your code
POST to the workflow execute endpoint with your API key and prompt parameters. The response returns an executionId immediately, so your app never blocks on render time.
Poll and collect the video
Poll the execution endpoint until status reads COMPLETED. The response includes hosted MP4 URLs with audio, generation metadata, and a per-node credit breakdown.
How the Seedance 2.5 API Workflow Runs
The workflow on this page runs in three steps.
- What you put in. A text prompt in the Text Input node, the shot you want in plain words. You can also pass a start frame or an end frame image to lock how the Seedance 2.5 clip opens or closes.
- What comes out. The Seedance 2.5 node returns a 5 second clip at 16:9 with sound generated in the same pass, ready to pull the Seedance 2.5 clip back into your code from one REST endpoint.
- What you can change. Edit the prompt, the duration or the aspect ratio, turn the audio off, or swap the Seedance 2.5 node for Seedance 2.0 and keep the rest of the call the same.
What You Can Run Through the API Today
Text-to-Video Generation
Turn a prompt into a finished clip through a workflow node, with control over aspect ratio, resolution, and motion style.
Image-to-Video with Reference Control
Animate a still image or pass a reference image as input to anchor the look, subject, and starting frame of a shot.
Video With Audio Attached
Models that generate sound alongside the video return finished clips with audio already in the file, so there is no separate dubbing step.
Swap Models Without Code Changes
Kling 3, Veo 3.1, and Seedance sit behind the same request shape. Change the node, not the integration, and Seedance 2.5 swaps in the same way.
Chain with Other Models
Pipe a Nano Banana 2 or Flux 2 Pro image straight into the video node, then upscale the result, all in one workflow.
Async Execution, Per-Node Cost
Submit a request, receive an executionId, poll until COMPLETED. Each response itemizes credit usage per node for cost tracking.
More Than Just Seedance 2.5 API
What ByteDance Announced
Seedance 2.5 does 30 seconds in one pass at native 4K and takes up to 50 reference inputs. The Seedance 2.5 page covers the confirmed specs in full. If you want your own voice on the clip, read how to get your real voice into a Seedance 2.5 video.
Run Seedance 2.5 Today
Call Seedance 2.5 through the Wireflow REST API at 27 credits a second. The workflow on this page runs Seedance 2.5 as a Wireflow node, and the Seedance API page covers the same REST interface.
Benchmark Against Veo 3.1
Veo 3.1 has an official developer API but needs scene-extension chaining past a single clip. The Veo 3.1 video API shares the exact REST interface here, so you can run the same prompt through both.
Built for Programmatic Pipelines
Raw model endpoints leave orchestration to you. Wireflow's programmatic video generation platform adds queues, retries, and cost controls so you ship video at scale from code.
Pay Per Generation, Capped
Video API bills spike fast at scale. Wireflow's usage-based AI API pricing charges per execution with spend limits, so a runaway queue cannot blow the budget.
