## 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": "mischief_1",
  "prompt": "Photorealistic nighttime pumpkin field, viewed from a low fixed camera through curling vines and mist. Keep the large ribbed pumpkin in the center foreground stable in size, position, stem, and natural texture. A classic jack-o'\''-lantern face visibly forms on its front: two triangular eyes, a small triangular nose, and a wide jagged smiling mouth, all emitting warm orange light through clean carved openings. Finish with the transformed glowing jack-o'\''-lantern holding still amid the dark field, fog, and distant pumpkins.",
  "files": [
    {
      "url": "https://tbc-public-assests.s3.us-west-2.amazonaws.com/fal/seed-image.png"
    }
  ],

## Inputs

| field | type | required | default | allowed | description |
|---|---|---|---|---|---|
| `model` | string | yes | — | `mischief_1` 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. 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. Supported by this model's routes: fal: 3, 5. A non-numeric value such as "auto" is routed to a route whose schema accepts it; when none does, the request is rejected. |

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 | — | — | What happens in the video. Long, specific prompts steer WAN best. |
| `seed` | integer | no | — | 0–2147483647 | — |
| `duration` | number | no | — | — | — |
| `image_url` | string (URL) | no | — | — | http(s) URL of the condition image the video starts from, at most 25 MiB and 100 megapixels. A JPEG or PNG within the endpoint's byte budget (2.5 MB by default) renders as sent; anything larger, and any other format, is re-encoded to fit (a JPEG stays JPEG, anything else becomes lossless PNG), scaled down only as far as needed and never below the requested resolution; where that resolution stops the shrink, it is sent as a JPEG of slightly lower quality instead. |
| `resolution` | string | no | — | 480p \| 720p | — |
| `image_transform` | string | no | — | center_crop \| resize | — |
| `prompt_processing` | string | no | — | original \| enhanced | — |

## Routes

`"model": "mischief_1"` 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:tbc/mischief-1/image-to-video` | fal | image-to-video | $0.005/s | ~30 s |
