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",[160],"pulls","branches","forks","envVars",{"_173":156,"_175":69},"connections",{"_173":69,"_174":69},"count","unfilledCount","emptyCount",{"_49":159,"_38":160,"_36":161,"_153":-5,"_47":48,"_46":162,"_154":65,"_44":182,"_13":69,"_39":26,"_41":164,"_30":31,"_157":-5,"_179":183,"_33":184},{"_49":152,"_38":34,"_36":37,"_153":-5,"_47":48,"_46":14,"_154":31,"_44":178,"_13":156,"_39":40,"_41":43,"_30":31,"_157":-5,"_179":180,"_33":181},["D",1781209192819],"children",[],[34],["D",1781209168141],[],[160],["D",1781209168141],{"_107":106,"_115":111},{"_107":106,"_108":109,"_110":111,"_19":62,"_112":113,"_114":31},{"_13":92,"_38":93,"_49":48,"_94":50,"_95":96,"_97":98,"_99":56,"_100":101,"_102":103,"_104":51,"_105":106},"ctx",{"_85":-5,"_137":222,"_223":224,"_225":226,"_227":31,"_228":31,"_229":31,"_230":65,"_231":-5,"_232":-7,"_233":-7,"_234":69,"_235":31,"_236":31,"_237":-5,"_238":31,"_239":31,"_240":31,"_241":-5},"ENV",{"_193":194,"_195":196,"_197":93,"_198":199,"_200":201,"_202":203,"_204":205,"_206":207,"_208":209,"_210":211,"_212":213,"_214":215,"_216":217,"_218":219,"_220":221},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
