## Call it

REST: `POST https://api.varg.ai/v2/tools/image/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/image/call \
  -H "Authorization: Bearer $VARG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "gpt_image_1",
  "prompt": "A photorealistic product photo of a coffee bag labeled \"Summit Roast\" with mountain artwork, on a rustic wooden table"
}'
```

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

```json
{
  "tool": "image",
  "input": {
    "model": "gpt_image_1",
    "prompt": "A photorealistic product photo of a coffee bag labeled \"Summit Roast\" with mountain artwork, on a rustic wooden table"
  },
  "wait": true
}
```
