# AIGC Kling VOD Guide

> Call Kling video models through Crazyrouter's AIGC Kling VOD route

# AIGC Kling VOD Guide

`aigc-video-kling-*` models are Kling video models exposed through Crazyrouter's Tencent VOD route. They do not use the native Kling `/kling/v1/videos/*` contract. Use the OpenAI-style async video route instead:

```http theme={null}
POST /v1/video/generations
GET /v1/video/generations/{task_id}
```

<Note>
  To use the VOD route, submit an `aigc-video-kling-*` model name. Do not submit `kling-v2-5-turbo`, `kling-v2-6`, or `kling-v3` here; those names may route to the native Kling provider.
</Note>

<Note>
  `GV 3.1`, `3.1-fast`, and `3.1-lite` in Tencent VOD are Google Veo models, not Kling 3.1. Use the separate `aigc-video-gv-*` models.

    ],
    "seconds": "5",

      "resolution": "720P",
      "sound": false
    }
  }'
```

<Note>

</Note>

## Multi-Reference Images

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

        "https://example.com/ref-2.png"
      ]
    }
  }'
```

## Motion Control

Use a dedicated motion-control model such as `aigc-video-kling-2.6-motion-control` or `aigc-video-kling-3.0-motion-control`.

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "aigc-video-kling-3.0-motion-control",
    "prompt": "animate the selected subject moving from left to right",
    "image": "https://example.com/input.png",
    "seconds": "5",
    "metadata": {
      "resolution": "720P",
      "dynamic_masks": [
        {
          "mask_url": "https://example.com/mask.png",
          "trajectories": [
            { "x": 220, "y": 380 },
            { "x": 620, "y": 380 }
          ]
        }
      ]
    }
  }'
```

## O1 Video Input

`aigc-video-kling-o1` accepts video references through `metadata.video_list`. Pricing can differ depending on whether video input is present.

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "aigc-video-kling-o1",
    "prompt": "use the reference video motion style and generate a new cinematic shot",
    "seconds": "5",
    "metadata": {
      "resolution": "720P",
      "video_list": [
        { "url": "https://example.com/reference.mp4" }
      ]
    }
  }'
```

## Avatar and Lip Sync

Avatar requests use `aigc-video-kling-avatar`:

```json theme={null}
{
  "model": "aigc-video-kling-avatar",
  "prompt": "a presenter speaks naturally to the camera",
  "image": "https://example.com/avatar.png",
  "seconds": "5",
  "metadata": {
    "resolution": "720P",
    "voice_list": [
      { "url": "https://example.com/voice.wav" }
    ]
  }
}
```

Lip sync uses `aigc-video-kling-identifyface`. If your workflow already has upstream `session_id` and `face_choose` values, pass them in `metadata`:

```json theme={null}
{
  "model": "aigc-video-kling-identifyface",
  "prompt": "lip sync the face with the provided voice",
  "image": "https://example.com/face.png",
  "seconds": "5",
  "metadata": {
    "resolution": "720P",
    "session_id": "SESSION_ID",
    "face_choose": "FACE_ID",
    "voice_list": [
      { "url": "https://example.com/voice.wav" }
    ]
  }
}
```

<Note>
  A full lip-sync workflow usually requires face identification before video generation. Without `session_id` / `face_choose`, the upstream may return a parameter error.
</Note>

## Query a Task

After creation returns `id` or `task_id`, query the same compatibility route:

```bash cURL theme={null}
curl https://api.crazyrouter.com/v1/video/generations/TASK_ID \
  -H "Authorization: Bearer YOUR_API_KEY"
```

Completed tasks usually return an archived video URL:

```json theme={null}
{
  "code": "success",
  "data": {
    "status": "SUCCESS",
    "task_id": "vod_task_abc123",
    "result_url": "https://media.crazyrouter.com/task-artifacts/example.mp4",
    "artifact_url": "https://media.crazyrouter.com/task-artifacts/example.mp4"
  }
}
```
