## Call it

REST: `POST https://api.varg.ai/v2/tools/speech/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/speech/call \
  -H "Authorization: Bearer $VARG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "eleven_turbo",
  "text": "Comment RECRUIT below — I'\''ll send you the link.",
  "voice": "XrExE9yKIg1WjnnlVkGX"
}'
```

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

```json
{
  "tool": "speech",
  "input": {
    "model": "eleven_turbo",
    "text": "Comment RECRUIT below — I'll send you the link.",
    "voice": "XrExE9yKIg1WjnnlVkGX"
  },
  "wait": true
}
```

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