# Wan Video
> Wan video family overview. Wan text-to-video uses /v1/video/generations; image-to-video, first-last-frame, and subject-reference workflows use the /alibailian/api/v1/* compatibility contract
> Дата обновления: 2026-06-07
# Wan Video
The Wan family currently uses different public contracts by capability:
* Text-to-video (`wan2.5-t2v-preview`, `wan2.2-t2v-plus`): submit with `POST /v1/video/generations` and query with `GET /v1/video/generations/{task_id}`.
* Image-to-video, first-last-frame, and subject-reference video: submit with the Ali Bailian-compatible `POST /alibailian/api/v1/services/aigc/video-generation/video-synthesis` path and query with `GET /alibailian/api/v1/tasks/{task_id}`.
Do not submit `wan2.2-t2v-plus` to `/alibailian/api/v1/services/aigc/video-generation/video-synthesis`. Production rejects that model on the Ali-compatible path with `invalid_request` and tells clients to use `/v1/video/generations`.
For Ali-shaped workflows, see the full request and task-query schema in [Ali Bailian Video API](/ru/video/alibailian). This page closes the first batch of public `Wan` models, capabilities, billing truth, and recommended protocol.
## First-Batch Models
| Model | Customer-facing capability | Official billing truth | Current state |
| -------------------- | -------------------------- | ---------------------- | ------------- |
| `wan2.5-t2v-preview` | text-to-video | per second | verified |
| `wan2.5-i2v-preview` | image-to-video | per second | verified |
| `wan2.2-t2v-plus` | text-to-video | per second | verified |
| `wan2.2-i2v-plus` | image-to-video | per second | verified |
| `wan2.2-i2v-flash` | image-to-video | per second | verified |
| `wan2.2-kf2v-flash` | first-last-frame video | per second | Beta |
| `wan2.2-s2v` | subject-reference video | per second | Beta |
`wan2.2-kf2v-flash` and `wan2.2-s2v` are already aligned in code and billing capability buckets, but their live artifact closure is still in progress, so they remain Beta.

## Request Examples
### Text-to-video: Wan 2.5
```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
-H "Content-Type: application/json" \

}'
```
### Text-to-video: Wan 2.2 T2V Plus

"model": "wan2.2-t2v-plus",
"prompt": "A calm cinematic shot of clouds over mountains",
"seconds": "5",
"size": "480P"
}'
```
### Image-to-video
```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/alibailian/api/v1/services/aigc/video-generation/video-synthesis \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{
"model": "wan2.5-i2v-preview",
"input": {
"prompt": "Make the subject turn toward the camera",
"img_url": "https://example.com/first-frame.png"
},
"parameters": {
"resolution": "720P",
"duration": 5,
"prompt_extend": true,
"audio": true
}
}'
```
### First-last-frame video
```json theme={null}
{
"model": "wan2.2-kf2v-flash",
"input": {
"prompt": "A smooth transition from day to night",
"first_frame_url": "https://example.com/frame-start.png",
"last_frame_url": "https://example.com/frame-end.png"
},
"parameters": {
"resolution": "720P",
"duration": 5
}
}
```
### Subject-reference video
```json theme={null}
{
"model": "wan2.2-s2v",
"input": {
"prompt": "Animate the reference portrait with light natural speaking motion",
"image_url": "https://example.com/portrait.png",
"audio_url": "https://example.com/voice.mp3"
},
"parameters": {
"resolution": "720P",
"duration": 5
}
}
```
## Task Retrieval
Wan remains an async task family. Query with the matching route for the submit contract.
Text-to-video:
```http theme={null}
GET /v1/video/generations/{task_id}
```
Ali-compatible image-to-video, first-last-frame, and subject-reference workflows:
```http theme={null}
GET /alibailian/api/v1/tasks/{task_id}
```
When `output.task_status` reaches success, use `output.video_url` as the final video result.
## Scope Notes
* The current recommended customer-facing contract for Wan text-to-video is `/v1/video/generations`, not the Ali Bailian-compatible submit path.
* The Ali Bailian-compatible path is primarily for image-to-video, first-last-frame, subject-reference, and other Ali-shaped migration workflows.
* Crazyrouter can internally route to official, ApiPass, Kie, or other third-party providers, but those providers do not define customer protocols.
* Beta rows can still be shown publicly now; after launch, use production task logs to close live evidence and then remove the Beta label.
