# Ali Bailian Video API

> Ali Bailian-compatible video routes. Clients use /alibailian/api/v1/* while Crazyrouter now proxies upstream to official DashScope /api/v1/* endpoints

# Ali Bailian Video API

Crazyrouter exposes Ali Bailian-compatible video routes so applications already using DashScope / Ali Bailian video formats can migrate with minimal path changes.

## 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

## Supported Endpoints

* `POST /alibailian/api/v1/services/aigc/video-generation/video-synthesis`
* `GET /alibailian/api/v1/tasks/{task_id}`

## Internal Upstream Mapping

* Public compatibility submit path: `POST /alibailian/api/v1/services/aigc/video-generation/video-synthesis`
* Public compatibility query path: `GET /alibailian/api/v1/tasks/{task_id}`
* Crazyrouter upstream submit path: `POST /api/v1/services/aigc/video-generation/video-synthesis`
* Crazyrouter upstream query path: `GET /api/v1/tasks/{task_id}`

## Authentication

```http theme={null}
Authorization: Bearer YOUR_API_KEY

<Warning>
  Submitting `wan2.2-t2v-plus` to this page's path returns `invalid_request` in production, with guidance to use `/v1/video/generations`. For Wan text-to-video, see [Wan Video](/ru/video/wan) or [Video Generation Alias](/ru/video/openai-video-alias-create).
</Warning>

}
```

## 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:

```json theme={null}
{
  "code": "task_not_exist",
  "message": "task_not_exist",
  "data": null
}
```

<Note>
  This path family is primarily for protocol-compatible migration. The request and response bodies stay much closer to native DashScope / Bailian conventions than to Crazyrouter's unified video schema. It also does not mean every Ali video model is publicly enabled on Crazyrouter; treat current pricing, token allowlists, and live channel bindings as the source of truth.
