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",[70],"pulls","branches","forks","envVars",{"_76":20,"_195":20},"connections",{"_76":20,"_194":20},"unfilledCount","emptyCount",{"_28":183,"_13":70,"_68":69,"_38":-5,"_30":31,"_176":35,"_177":101,"_32":202,"_34":20,"_71":49,"_179":185,"_72":24,"_181":-5,"_199":203,"_141":204},{"_28":175,"_13":80,"_68":79,"_38":-5,"_30":31,"_176":77,"_177":101,"_32":198,"_34":35,"_71":81,"_179":180,"_72":24,"_181":-5,"_199":200,"_141":201},["D",1781193029735],"children",[],[80],["D",1781193019605],[],[70],["D",1781193019605],{"_11":12,"_140":75},{"_11":12,"_135":136,"_74":75,"_25":73,"_137":138,"_139":24},{"_34":77,"_13":16,"_28":31,"_124":89,"_125":65,"_126":127,"_128":93,"_129":130,"_131":132,"_133":14,"_134":12},"ctx",{"_47":-5,"_162":242,"_243":244,"_245":246,"_247":24,"_248":24,"_249":24,"_250":101,"_251":-5,"_252":-7,"_253":-7,"_254":20,"_255":24,"_256":24,"_257":-5,"_258":24,"_259":24,"_260":24,"_261":-5},"ENV",{"_213":214,"_215":216,"_217":16,"_218":219,"_220":221,"_222":223,"_224":225,"_226":227,"_228":229,"_230":231,"_232":233,"_234":235,"_236":237,"_238":239,"_240":241},"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"]
