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 rules.",[146],"pulls","forks","envVars",{"_157":159,"_160":159},"connections",{"_157":57,"_158":57},"count","unfilledCount",2,"emptyCount",{"_20":145,"_13":146,"_132":147,"_133":-5,"_134":21,"_135":30,"_136":53,"_22":167,"_29":57,"_138":108,"_140":149,"_142":40,"_143":-5,"_164":168,"_96":169},{"_20":130,"_13":131,"_132":51,"_133":-5,"_134":21,"_135":30,"_136":53,"_22":163,"_29":57,"_138":139,"_140":141,"_142":40,"_143":-5,"_164":165,"_96":166},["D",1781553205533],"children",[],[131],["D",1781553205533],[],[146],["D",1781553205533],{"_11":12,"_94":90},{"_11":12,"_87":88,"_89":90,"_48":49,"_91":92,"_93":40},{"_29":30,"_13":26,"_20":21,"_27":28,"_31":32,"_33":34,"_80":42,"_81":82,"_83":84,"_85":14,"_86":12},"ctx",{"_73":-5,"_118":207,"_208":209,"_210":211,"_212":40,"_213":40,"_214":40,"_215":53,"_216":-5,"_217":-7,"_218":-7,"_219":57,"_220":40,"_221":40,"_222":-5,"_223":40,"_224":40,"_225":40,"_226":-5},"ENV",{"_178":179,"_180":181,"_182":26,"_183":184,"_185":186,"_187":188,"_189":190,"_191":192,"_193":194,"_195":196,"_197":198,"_199":200,"_201":202,"_203":204,"_205":206},"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"]
