Quickstart
Get started with the Seedance 2.0 API in 3 steps
From sign-up to your first Seedance 2.0 API call in under 5 minutes.
Create a RouterBase API key
Sign up and generate sk-rb-… — one key works across the Seedance 2.0 API and 200+ other models on RouterBase.
POST your prompt
Send your prompt, duration, and resolution in JSON to the Seedance 2.0 API endpoint. The call is async — RouterBase polls upstream until the render completes, then returns a signed URL.
Inspect the result
Each Seedance 2.0 API response includes generation metadata for auditing and a render URL ready to embed in your product.
Pay only for what you use
