## Call it

REST: `POST https://api.varg.ai/v2/tools/video/call` with `Authorization: Bearer $VARG_API_KEY` (create a key at https://varg.ai/dashboard/api).
It answers `202` with a job right away. Poll `GET /v2/jobs/{id}` until `status` is `completed`, then read `output.outputs[0].url` — or pass `options.webhook_url` and get the finished job POSTed to you.

```bash
curl -X POST https://api.varg.ai/v2/tools/video/call \
  -H "Authorization: Bearer $VARG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "minimax_h3_max_3d_to_video",
  "prompt": "The moving block represents a running person.",
  "files": [
    {
      "url": "https://example.com/blender-previs.mp4"
    }
  ]
}'
```

MCP: the varg server `https://mcp.varg.ai/mcp` (OAuth sign-in, no key) runs it with `call_tool`:

```json
{
  "tool": "video",
  "input": {
    "model": "minimax_h3_max_3d_to_video",
    "prompt": "The moving block represents a running person.",
    "files": [
      {
        "url": "https://example.com/blender-previs.mp4"
      }
    ]
  },
  "wait": true
}
```

## Inputs

| field | type | required | default | allowed | description |
|---|---|---|---|---|---|
| `model` | string | yes | — | `minimax_h3_max_3d_to_video` or a route key below | Which model runs the job. |
| `prompt` | string | no | — | — | — |
| `files` | array of { url } | no | — | — | — |
| `aspect_ratio` | string | no | — | e.g. 16:9 \| 9:16 \| 1:1 \| 4:3 \| 3:4 \| 21:9 \| auto | — |
| `resolution` | string | no | — | 480p \| 720p \| 1080p \| 4k | Quality tier. Supported by this model: 480p, 720p, 1080p. Unsupported tiers fall back to the nearest available. |
| `audio` | boolean | no | — | — | Native audio track request. Not supported by this model — ignored if sent. |
| `duration` | integer | no | — | 1–120 | Length in seconds. Not mapped by this model — ignored if sent. |

Media inputs are URLs. Upload a local file first with `POST /v2/files` and pass the returned URL.

## Provider options

Optional, per provider, under `provider_options.<provider>`. Only the options of the provider that runs the job apply — pin a route to choose it.

### provider_options.fal

| field | type | required | default | allowed | description |
|---|---|---|---|---|---|
| `prompt` | string | no | — | — | — |
| `reference_image_urls` | array of URL strings | no | — | — | — |
| `video_url` | string (URL) | no | — | — | Blender video, up to 15 seconds and 32 shots, at a public HTTPS URL. |
| `resolution` | string | no | — | 480P \| 768P \| 1080P | — |
| `max_generated_reference_images` | integer | no | — | 1–8 | Maximum NEW images to generate when no reference images are supplied. Ignored when reference images are supplied. Uses fewer when enough views are covered. Uncovered shots stay in the video. |

## Routes

`"model": "minimax_h3_max_3d_to_video"` picks a route automatically (priority order, then the inputs you send). To pin one, pass its key as `model`.

| model key | provider | modality | price from | typical time |
|---|---|---|---|---|
| `fal:minimax/h3-max/3d-to-video` | fal | video-to-video | $0.90 | ~2 min |
