API docs for the generation surfaces you are actually opening up

Start from the unified entry, then jump into the video or image API track that matches your product. Keep the Seedance-specific pages as dedicated deep links for campaign and partner traffic.

The public API is now organized by capability first, then by model

This keeps the top-level docs stable even as the model lineup grows. Capability pages explain the surface area. Model pages absorb launch traffic and model-specific expectations.

Architecture

How the public API structure should behave as you add more models

Shared infrastructure

Authentication, API keys, async jobs, and the task polling lifecycle should stay consistent across every public surface.

Capability pages

Use Video API and Image API as the top-level explanation layer for what each public surface includes.

Model-specific pages

Use Seedance 2, Seedance 2.5, and future model pages for campaign traffic, release intent, and model-specific onboarding.
