# Create a phone demo

## In the studio

1. Open [Phone demo studio](https://phone-demo.jetskibay.com).
2. Upload a screenshot or screen recording.
3. Choose **Stock image** for PNG or **Demo video** for a six-second silent MP4.
4. Enter your private Jetskibay access token and select **Create**.
5. Download the result within 24 hours.

The first render may take a few minutes. Keep this tab open until your result is ready. Your token is held only in this tab. Anyone with a private download link can access that result until it expires.

## With an AI assistant

Connect your MCP client to `https://phone-demo.jetskibay.com/mcp`, using `Authorization: Bearer <PHONE_DEMO_TOKEN>`. Ask your Jetskibay operator for a private token. Anonymous access can read this guide and the catalogue, but cannot execute tools.

Available tools:

- `create_upload({content_type})` returns `upload_id` and a private `upload_url`. PUT the file bytes to that URL with the matching Content-Type.
- `create_demo({upload_id, output})` starts a demo. `output` is `image` or `video` (default `image`).
- `get_demo({job_id})` reports `queued`, `rendering`, `succeeded`, `failed`, or `expired`. A successful result includes `download_url` and `expires_at`.

Through Jetskibay's authenticated gateway at `https://jetskibay.com/mcp`, use your gateway token and these names: `phone-demo__create_upload`, `phone-demo__create_demo`, and `phone-demo__get_demo`. The upstream credential is managed by Jetskibay. MCP protocol revision: `2026-07-28`.

Example successful job response (illustrative):

```json
{"job_id":"00000000-0000-4000-8000-000000000000","status":"succeeded","output":"image","download_url":"https://phone-demo.jetskibay.com/files/<job-id>?key=<private-download-key>","media_type":"image/png","expires_at":"<ISO timestamp>"}
```

## File requirements

PNG, JPEG, WebP, MP4, MOV, or WebM; maximum 40 MiB and 16 megapixels. Use SDR for video. Portrait screens fit best; other shapes are centered with padding. Video output is six seconds at 24 fps, without audio. Recordings play at their original speed; shorter recordings hold their last frame. Image output uses the first frame of a recording.

Invalid files return a failed job with a useful message. If rendering times out after 15 minutes, submit a new job. Missing or invalid credentials return HTTP 401. Uploads and results have private URLs that expire after 24 hours. Storage is scheduled for automatic deletion after one day; physical deletion may follow later.
