Vapi hosts the telephony and the live\naudio bridge to the model, so the whole demo is one POST to\n`https://api.vapi.ai/call` — one file, about seventy lines, no imports.\n\n## Setup\n\n1. **Remix this val** to get your own copy.\n2. **Get a Vapi API key** — sign up at\n [dashboard.vapi.ai](https://dashboard.vapi.ai) and copy your private key,\n then paste it as an env var in your val:\n\n 👉\n [Add `VAPI_API_KEY` here](https://www.val.town/x/templates/vapi-phone-call/environment-variables?key=VAPI_API_KEY)\n\n3. **Create a phone number** in the Vapi dashboard (free Vapi numbers work for\n testing) and copy its ID:\n\n 👉\n [Add `VAPI_PHONE_NUMBER_ID` here](https://www.val.town/x/templates/vapi-phone-call/environment-variables?key=VAPI_PHONE_NUMBER_ID)\n\n## Test it\n\nOpen the HTTP endpoint of\n[`main.ts`](https://www.val.town/x/templates/vapi-phone-call/code/main.ts), type\nyour own number in E.164 format (`+15551234567`), and hit **Call me**. Your\nphone rings and the AI speaks first. Without the env vars set, the page shows a\nsetup reminder instead of erroring.\n\n## Files\n\n- [`main.ts`](https://www.val.town/x/templates/vapi-phone-call/code/main.ts) —\n the form, and the one `fetch` that places the call\n\n## Notes\n\n- `FIRST_MESSAGE`, `SYSTEM_PROMPT`, `MODEL`, and `VOICE` at the top of `main.ts`\n control what the AI opens with, how it behaves, and how it sounds.\n- Free Vapi numbers are US-only and meant for testing.\n- From here you can add tool calls, transcripts, and post-call analysis — see\n [docs.vapi.ai](https://docs.vapi.ai).\n- Only call numbers you have consent to call — automated calls without consent\n violate TCPA/FCC
