What the Seedance API Gives You

Seedance 2.0 is ByteDance's flagship video generation model. It handles text-to-video, image-to-video with first and last frame control, and reference-to-video, and it is known for strong motion fidelity, character consistency, and multi-shot narrative output in clips up to 15 seconds. Direct access runs through ByteDance's own cloud platforms, so most teams outside China reach the model through third-party API providers instead.

Most of those providers give you a raw single-model endpoint and stop there. Wireflow treats Seedance as one node in a larger pipeline: prototype the workflow on a visual canvas, chain Seedance with image generators, upscalers, and LLM prompt steps, then call the whole pipeline as a single REST endpoint with one Bearer token. You get the model plus the orchestration layer production apps actually need, including async execution, per-node cost reporting, and model swaps without code changes.

Seedance 2.0 Capabilities Through the API

🎬

Text-to-Video Generation

Generate cinematic clips from a text prompt, with control over aspect ratio, duration, and motion style.

🖼️

Image-to-Video with Frame Control

Animate a still image, or pin first and last frames to control exactly where a shot starts and ends.

🎭

Character Consistency

Reference inputs keep faces, outfits, and visual style stable across shots, a known strength of Seedance 2.0.

🔗

Chain with Other Models

Pipe a Nano Banana 2 or Flux 2 Pro image straight into a video node, then upscale the result, all in one workflow.

🔄

Async Execution Pattern

Submit a request, receive an executionId, poll until COMPLETED. Predictable states built for production queues.

💰

Per-Node Cost Reporting

Every execution response itemizes credit usage per node, so you can track exact cost per second of video.

Benchmark Against Kling 3

Run the same prompt through two video models in parallel branches and compare output before committing. Kling Video 3 sits one node swap away in the same workflow.

Built for Programmatic Pipelines

Raw model endpoints leave orchestration to you. Our comparison of the best programmatic video generation platforms shows why a workflow layer beats stitching providers together by hand.

Prototype Visually, Ship via REST

Design and test the pipeline on a canvas before writing integration code. The node-based video generation editor and the API execute the exact same workflow definition.

Pay Per Generation, Capped

Video API bills can 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.

FAQs

What is the Seedance API?
It is programmatic access to Seedance 2.0, ByteDance's video generation model. The API accepts text prompts, images, and reference material, and returns MP4 video with strong motion fidelity, character consistency, and multi-shot narrative support.
Does ByteDance offer direct Seedance API access?
Direct access runs through ByteDance's cloud platforms, Volcano Engine and BytePlus, which are oriented toward enterprise accounts. Most developers outside China use third-party providers that expose Seedance 2.0 through standard REST endpoints instead.
What inputs does Seedance 2.0 accept?
Text prompts, images for image-to-video including first and last frame control, and reference material for character and style consistency. Output is MP4 video in aspect ratios from 21:9 down to 9:16.
How long can Seedance 2.0 videos be?
Generations range from roughly 4 to 15 seconds per clip depending on settings. For longer content, chain multiple generations in a workflow and use last-frame control to keep continuity between consecutive shots.
How does Seedance 2.0 compare to Kling 3 and Veo 3.1?
Seedance leads on character consistency and multi-shot narrative output. Kling 3 is strong on motion realism and physics, while Veo 3.1 excels at prompt adherence with native audio. Running all three through one platform makes direct comparison practical.
How does authentication work on Wireflow?
Generate an API key from the dashboard under Settings and send it as a Bearer token in the Authorization header. One key covers every model on the platform, including video, image, and LLM nodes.
Can I combine Seedance with image generation models?
Yes. A common pattern generates a styled keyframe with an image model first, then feeds it into the video node as the start frame. The whole chain executes as one API call with a single executionId.
How much does Seedance video generation cost?
Pricing is usage-based per generation and scales with resolution and duration. Each execution response includes a per-node credit breakdown, and account-level spend limits cap total monthly usage automatically.
