Vapi hosts the telephony and the live audio bridge to the model, so the whole demo is one POST to `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 [dashboard.vapi.ai](https://dashboard.vapi.ai) and copy your private key, then paste it as an env var in your val:\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 testing) and copy its ID:\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 [`main.ts`](https://www.val.town/x/templates/vapi-phone-call/code/main.ts), type your own number in E.164 format (`+15551234567`), and hit **Call me**. Your phone rings and the AI speaks first. Without the env vars set, the page shows a setup reminder instead of erroring.\n\n## Files\n\n- [`main.ts`](https://www.val.town/x/templates/vapi-phone-call/code/main.ts) — 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` control what the AI opens with, how it behaves, and how it sounds.\n- Call screening (like Google Voice's) answers before you do, so the AI spends its greeting on the screening robot and you join to silence — turn screening off when testing.\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 [docs.vapi.ai](https://docs.vapi.ai).\n- Only call numbers you have consent to call — automated calls without consent violate TCPA/FCC rules.\n",[80],{"_35":79,"_13":80,"_62":81,"_64":-5,"_65":66,"_67":31,"_69":70,"_37":92,"_17":83,"_72":24,"_74":84,"_76":50,"_77":-5,"_89":93,"_18":94},{"_35":60,"_13":61,"_62":63,"_64":-5,"_65":66,"_67":68,"_69":70,"_37":88,"_17":31,"_72":73,"_74":75,"_76":50,"_77":-5,"_89":90,"_18":91},["D",1781193029735],"children",[],[61],["D",1781193019605],[],[80],"09778dcd-f187-4d65-9465-f180f522212d",["D",1781193019605],"legacyEnvVars","httpPrivacy","description","Make
