You can access the app via WebRTC at\n[hello-realtime.val.run](https://hello-realtime.val.run), or via SIP by calling\n425-800-0042.\n\nThis demo shows off the new SIP API, the new all-in-one WebRTC API, and the new\nserver-side websocket interface.\n\nIf you remix the app, you'll just need to pop in your own `OPENAI_API_KEY` (from\n[platform.openai.com](https://platform.openai.com)), and if you want SIP, the\n`OPENAI_SIGNING_SECRET`.\n\n## Architecture\n\n1. **WebRTC Flow**:\n - Browser connects to frontend\n - creates WebRTC offer\n - `/rtc` endpoint handles SDP negotiation with OpenAI\n - observer established to monitor session\n2. **SIP Flow**:\n - Phone calls triggers webhook\n - `/sip` endpoint verifies webhook and accepts call\n - observer established to monitor session\n\n## API Endpoints\n\n- `GET /` - serves the WebRTC-based app\n- `POST /rtc` - creates a new WebRTC-based Realtime API session\n - Supports optional `model` URL parameter to override the default model\n - Example: `POST /rtc?model=gpt-4o-realtime-preview`\n- `POST /sip` - handles an incoming Realtime API SIP call\n- `POST /observer` - internal endpoint to establish a Realtime API websocket for\n session control\n\n## Project Structure\n\n```\n├── frontend/ \n│ └── index.html # HTML/JS application for WebRTC\n├── main.tsx # Main entrypoint for the val.town app\n└── routes/\n |\n ├── agent.ts # Realtime API session configuration and tools\n ├── observer.ts # Server-side session control for SIP & WebRTC\n ├── rtc.ts # WebRTC session setup\n ├── sip.ts # SIP webhook handling and session setup\n └── utils.ts # Various HTTP helpers\n```\n\n## File Links\n\n- [`frontend/index.html`](./frontend/index.html)\n- [`main.tsx`](./main.tsx)\n- [`routes/agent.ts`](./routes/agent.ts)\n- [`routes/observer.ts`](./routes/observer.ts)\n- [`routes/rtc.ts`](./routes/rtc.ts)\n- [`routes/sip.ts`](./routes/sip.ts)\n- [`routes/utils.ts`](./routes/utils.ts)",[174],"650ee3e8-53c4-11f1-9542-ee650bb23af1","routes","019e4201-4376-74f8-ae4a-64add1b7cf5c",["D",1779223839498],"directory",[180],"64e1839e-53c4-11f1-9542-ee650bb23af1","frontend","019e4201-4376-74f8-ae4a-4d0ad753bc42",["D",1779223839498],[186],"pulls","branches","forks","envVars",{"_197":168,"_199":153},"connections",{"_197":64,"_198":64},"count","unfilledCount","emptyCount",{"_44":185,"_32":186,"_30":187,"_152":-5,"_42":43,"_41":153,"_154":60,"_39":306,"_13":64,"_34":183,"_36":-5,"_24":25,"_157":-5,"_217":307,"_27":308},{"_44":299,"_32":300,"_30":301,"_152":187,"_42":43,"_41":153,"_154":60,"_39":302,"_13":64,"_34":20,"_36":303,"_24":25,"_157":-5,"_217":304,"_27":305},{"_44":292,"_32":293,"_30":294,"_152":187,"_42":43,"_41":153,"_154":60,"_39":295,"_13":64,"_34":35,"_36":296,"_24":25,"_157":-5,"_217":297,"_27":298},{"_44":283,"_32":284,"_30":285,"_152":187,"_42":43,"_41":286,"_154":25,"_39":287,"_13":288,"_34":20,"_36":289,"_24":25,"_157":-5,"_217":290,"_27":291},{"_44":276,"_32":277,"_30":278,"_152":187,"_42":43,"_41":153,"_154":60,"_39":279,"_13":64,"_34":20,"_36":280,"_24":25,"_157":-5,"_217":281,"_27":282},{"_44":179,"_32":180,"_30":181,"_152":-5,"_42":43,"_41":153,"_154":60,"_39":273,"_13":64,"_34":183,"_36":-5,"_24":25,"_157":-5,"_217":274,"_27":275},{"_44":264,"_32":265,"_30":266,"_152":181,"_42":43,"_41":267,"_154":25,"_39":268,"_13":269,"_34":35,"_36":270,"_24":25,"_157":-5,"_217":271,"_27":272},{"_44":256,"_32":257,"_30":258,"_152":181,"_42":43,"_41":259,"_154":60,"_39":260,"_13":138,"_34":35,"_36":261,"_24":25,"_157":-5,"_217":262,"_27":263},{"_44":249,"_32":250,"_30":251,"_152":181,"_42":43,"_41":153,"_154":60,"_39":252,"_13":64,"_34":35,"_36":253,"_24":25,"_157":-5,"_217":254,"_27":255},{"_44":244,"_32":33,"_30":31,"_152":181,"_42":43,"_41":14,"_154":25,"_39":245,"_13":246,"_34":35,"_36":38,"_24":25,"_157":-5,"_217":247,"_27":248},{"_44":237,"_32":238,"_30":239,"_152":181,"_42":43,"_41":153,"_154":60,"_39":240,"_13":64,"_34":35,"_36":241,"_24":25,"_157":-5,"_217":242,"_27":243},{"_44":229,"_32":230,"_30":231,"_152":181,"_42":43,"_41":232,"_154":60,"_39":233,"_13":153,"_34":35,"_36":234,"_24":25,"_157":-5,"_217":235,"_27":236},{"_44":173,"_32":174,"_30":175,"_152":-5,"_42":43,"_41":153,"_154":25,"_39":226,"_13":64,"_34":20,"_36":177,"_24":25,"_157":-5,"_217":227,"_27":228},{"_44":166,"_32":167,"_30":58,"_152":-5,"_42":43,"_41":168,"_154":60,"_39":223,"_13":153,"_34":163,"_36":170,"_24":25,"_157":171,"_217":224,"_27":225},{"_44":159,"_32":160,"_30":161,"_152":-5,"_42":43,"_41":153,"_154":60,"_39":220,"_13":64,"_34":163,"_36":164,"_24":25,"_157":-5,"_217":221,"_27":222},{"_44":149,"_32":150,"_30":151,"_152":-5,"_42":43,"_41":153,"_154":60,"_39":216,"_13":64,"_34":35,"_36":156,"_24":25,"_157":-5,"_217":218,"_27":219},["D",1779223839498],"children",[],[150],["D",1779223839498],[],[160],["D",1779223896398],[],[167],["D",1779223839498],[],[174],"91253eb0-5ba7-11f1-9b97-ee650bb23af1","utils.ts","019e4201-4376-74f8-ae4a-601e8e7c7198",72,["D",1780091067776],"const REALTIME_BASE_URL = \"https://api.openai.com/v1/realtime\";\nconst OPENAI_API_KEY = Deno.env.get(\"OPENAI_API_KEY\");\n\n// Whether an OpenAI key is configured on this deployment.

The user sees the *deployed page* of a single val in an iframe on the left and talks to you out loud. Everything above about working with Val Town vals still applies — you have the **val_town_mcp** tools (\\`list_files\\`, \\`read_file\\`, \\`update_file\\`, \\`create_file\\`, \\`create_val\\`, \\`get_val_detail\\`, etc.). Always pass the val identifier as the \\`val\\` argument. In addition, this workspace gives you these control tools:\n\n- **load_val(val)** — swap which val's deployed page is shown in the iframe. Pass a \"handle/name\" identifier. Use for \"open my X\", \"show Y\", \"switch to Z\".\n- **navigate_page(path)** — keep the *same* val loaded but point the iframe at a different route within it (e.g. \\`/forklift\\` or \\`/\\`). A bare slug (\"forklift\") is accepted. Use for \"go to the X page\", \"next/previous example\", \"back to the home/gallery\". This is NOT for switching vals — use \\`load_val\\` for that.\n- **slide_next / slide_prev / slide_goto(index)** — if the loaded val is a slideshow (it listens for \\`slideshow:next/prev/goto\\` postMessage events), drive it. Safe no-op on vals that don't listen.\n- **reload_site** — reload the iframe to show your latest edits. The preview does not auto-refresh.\n- **set_scene(scene)** — trigger a pre-built overlay/modal on the loaded page without reloading (see the Scenes guide below). \\`set_scene(\"\")\\` closes it.\n\n## Choreography & scenes\n\nSome vals ship a **\\`CHOREOGRAPHY.md\\`** at their root — director's notes listing the val's pages, the \\`set_scene\\` overlays you can trigger, and a loose suggested flow. **When you load a val, read its CHOREOGRAPHY.md once** (e.g. \\`read_file(\"dcm31/design-gallery\", \"CHOREOGRAPHY.md\")\\`) if it has one, and let it make you a better host — but keep everything **spontaneous and natural**: improvise, follow the user's lead, and never recite the notes or announce that you're reading them. Trigger a page's overlays with \\`set_scene(name)\\` (names live in that file); \\`set_scene(\"\")\\` closes them. \\`dcm31/design-gallery\\` is the main showcase and has a full CHOREOGRAPHY.md.\n\n## Studio rules\n- ${\n username\n ? `The user's Val Town handle is **${username}**. When they say \"open foo\" without an owner, default to \\`load_val(\"${username}/foo\")\\`. If they say \"Steve's val foo\", use \\`load_val(\"stevekrouse/foo\")\\`.`\n : `When the user names a val without an owner, assume it's theirs.`\n }\n- The studio can only display vals that have an **HTTP file**. When creating a new val to show, call \\`create_val\\` with \\`initialFile.fileType: \"http\"\\` (a minimal Hono app exporting \\`app.fetch\\`), then \\`load_val\\` it. Don't pass a \\`description\\` of 64+ chars (the validator rejects it). If \\`load_val\\` says \"no HTTP file\", add one via \\`create_file\\` with \\`fileType: \"http\"\\` and retry.\n- The preview does **not** auto-refresh. When you've finished editing (all file writes for this request are done), call **reload_site** once so the user sees the new version. Don't reload after every individual file — batch the edits, then reload at the end. The user can also hit the \"Reload site\" button themselves.\n- **Be terse — this is voice, and the user can see the page.** Confirm in one short sentence (\"Updated main.tsx — added the button.\" / \"Created and loaded ${\n username || \"your-handle\"\n }/foo.\"). Don't read code aloud unless asked. Before a non-trivial change, say in one line what you'll do.\n- Treat the user as the val's owner.\n- ${\n initialVal\n ? `The val currently loaded in the studio is: **${initialVal}**.`\n : `No val is loaded yet. If the user asks to edit something, either open one of their vals with \\`load_val\\` or offer to create a fresh one — don't just ask \"which val?\" and stop.`\n }\n\n## Assume the person might be brand new — to this, and to Val Town\n\nMany people here are **complete newcomers**. They may have clicked a link, signed up moments ago, and have *no idea* what this is, what a \"val\" is, or what Val Town does. Some have never written a line of code. **Never assume prior knowledge.** Your job is to make them feel like building something is easy and fun, starting from zero.\n\n- **Open by orienting them, briefly, only if they seem lost** (they go quiet, say \"what is this?\", \"how does this work?\", \"I don't know what to do\"). One or two warm sentences, plain language, no jargon:\n > \"This is a place where you can build little websites and apps just by talking to me — I write the code, and it goes live instantly on the page to your left. Want to make something? Tell me an idea, even a rough one, and I'll start.\"\n- **If they ask what Val Town is:** it's a website where you can create and run small web apps, sites, and automations in the cloud — nothing to install, no setup, and whatever you make gets a real live link you can share. A **\"val\"** is just one of those projects — the thing showing in the panel on the left.\n- **Offer a concrete first step instead of an open-ended question.** Newcomers freeze on \"what do you want to build?\" Suggest 2–3 tiny, delightful options: \"a personal homepage\", \"a countdown to your birthday\", \"a tip calculator\", \"a page that tells a dad joke\". Then **just build it** — \\`create_val\\` (with \\`initialFile.fileType: \"http\"\\`), \\`load_val\\` it, and show them.\n- **Translate, don't lecture.** Avoid \"deploy\", \"endpoint\", \"HTTP handler\", \"Deno\", \"repo\", \"commit\". Say \"it's live\", \"your page\", \"the link\", \"the code\". Only go technical if *they* do.\n- **Narrate lightly so the magic is visible.** \"Okay — making you a page now… done, take a look on the left. Want it a different color?\" Keep it to a sentence; they can see the result.\n- **Never make them feel behind.** No \"as you probably know\", no assuming they understand a term. Celebrate small wins.\n- They don't need to type anything or learn commands — talking is enough. (They *can* also type a val name in the box on the page, or click **✨ Create a new val**, but you can do all of that for them by voice.)`;\n}\n\nfunction buildSystemPrompt(initialVal?: string, username?: string): string {\n return `${towniePrompt}${studioAddendum(initialVal, username)}`;\n}\n\n// Builds the declarative session config. accessToken is required to give the\n// AI val.town MCP access; initialVal seeds the system prompt.

Voice Edit SDK

\n One line of code, and any Val Town val gets a little green circle in\n the corner that lets you voice-edit its source.\n

\n\n

Usage — Hono

Two lines added to any val you own. The val identifier is auto-detected:

import { voiceEdit } from \"https://esm.town/v/dcm31/voice-edit-sdk/sdk.ts\";\napp.use(voiceEdit());

\n\n

Usage — plain fetch handler

import { wrapFetch } from \"https://esm.town/v/dcm31/voice-edit-sdk/sdk.ts\";\nexport default wrapFetch(myHandler);

\n\n

Or: plain HTML snippet

If you'd rather paste a script tag into your HTML:

<script src=\"/sdk.js\" data-val=\"handle/name\" defer></script>

\n\n

What it does

\n Adds a small green circle in the bottom-right corner. Click to expand\n a login card, sign in with Val Town, then click again to start talking.\n The AI uses your Val Town MCP token to read and edit the host val's\n source — say things like \"add a button that says hello\" or\n \"in main.tsx, change the title to 'Welcome'\". Refresh the\n page to see edits live.\n

\n\n

How it works

\n The script injects an <iframe> pointing at this\n val's /widget page.\n
\n The widget runs same-origin, so OAuth, WebRTC, and audio all live\n inside it — no cross-origin cookie or CORS issues.\n
\n On connect, the OpenAI Realtime API is given the Val Town MCP server\n plus your access token, scoped to the val you specified.\n
\n The circle pulses with the AI's voice volume via an\n AnalyserNode on the remote audio track.\n
