Ali Bailian Video API

​

What This Page Covers

• This page documents Crazyrouter’s Ali-compatible public alias for workflows already integrated against the DashScope / Ali Bailian video body shape; those workflows can continue using /alibailian/api/v1/*
• Internally, Crazyrouter now talks to the official DashScope upstream through /api/v1/*
• If you want Crazyrouter’s unified video API rather than the Ali-compatible migration path, use /v1/video/generations
• Wan text-to-video currently uses /v1/video/generations. In particular, wan2.2-t2v-plus is not supported on this page’s /alibailian/...video-synthesis submit path.
• Actual model availability still depends on your token allowlist, pricing configuration, and current production channel bindings; do not assume every upstream Ali model is enabled by default

​

Error Behavior Verified Locally

• the local environment confirmed the create route exists; when a model is unavailable it returns a business error such as model_not_found rather than 404
• the local environment also confirmed the query route exists; a nonexistent task returns:

{
  "code": "task_not_exist",
  "message": "task_not_exist",
  "data": null
}
