\n\n\n\n\n`;\n\nconst SYSTEM_PROMPT =\n \"You are answering questions on behalf of Jon Gwynne about iTabs, a QR-based digital menu and preorder system for food venues, built solo by Jon, a Perth boilermaker with no formal coding background who directs AI to build the platform. Answer briefly (2-4 sentences), plainly, honestly, no sales-speak. \" +\n \"How iTabs works for a venue: a mobile-first menu customers browse and order from via QR code, no app download required. Every menu is built using Studio, an internal AI tool: a vendor photographs their existing menu, Studio reads it, brands it to their colours, and deploys it live in minutes — no designer, no developer needed. Venues run either a free simple tier where orders come through via WhatsApp, or a premium tier fully integrated with Square POS so orders fire straight into the till. \" +\n \"The business thesis: independent venues without in-house developers can't afford a custom ordering build, and third-party platforms like Uber Eats take a cut of every order. iTabs gives small venues a modern ordering experience without that overhead or commission. \" +\n \"Current proof phase: Allendale Square food court in Perth, where seven venues have menus built. Nobody is paying yet, but conversations are underway. The bigger opportunity being explored is a single link-out from a landlord's own venue directory (many of which dead-end at a Facebook page) into the iTabs directory for that food court, live now at https://allendale-square-food.val.run/. \" +\n \"If asked about pricing, say pricing isn't finalised yet and Jon can discuss numbers directly. If you don't know something, say so honestly and suggest emailing Jon at jgwynne7@gmail.com.\";\n\nexport default async function (req: Request): Promise {\n const url = new URL(req.url);\n\n if (req.method === \"GET\" && url.pathname === \"/og-image.png\") {\n const bytes = Uint8Array.from(\n atob(OG_IMAGE_BASE64),\n (c) => c.charCodeAt(0),\n );\n return new Response(bytes, {\n headers: {\n \"Content-Type\": \"image/png\",\n \"Cache-Control\": \"public, max-age=86400\",\n },\n });\n }\n\n if (req.method === \"POST\" && url.pathname === \"/ask\") {\n try {\n const body = await req.json();\n const question = (body?.question ?? \"\").toString().slice(0, 500);\n if (!question) {\n return new Response(JSON.stringify({ error: \"No question provided\" }), {\n status: 400,\n headers: { \"Content-Type\": \"application/json\" },\n });\n }\n\n const apiKey = Deno.env.get(\"ANTHROPIC_API_KEY\");\n if (!apiKey) {\n return new Response(\n JSON.stringify({ error: \"API key not configured\" }),\n {\n status: 500,\n headers: { \"Content-Type\": \"application/json\" },\n },\n );\n }\n\n const aiRes = await fetch(\"https://api.anthropic.com/v1/messages\", {\n method: \"POST\",\n headers: {\n \"Content-Type\": \"application/json\",\n \"x-api-key\": apiKey,\n \"anthropic-version\": \"2023-06-01\",\n },\n body: JSON.stringify({\n model: \"claude-haiku-4-5-20251001\",\n max_tokens: 400,\n system: SYSTEM_PROMPT,\n messages: [{ role: \"user\", content: question }],\n }),\n });\n\n if (!aiRes.ok) {\n const errText = await aiRes.text();\n console.error(\"Anthropic API error:\", errText);\n return new Response(JSON.stringify({ error: \"AI request failed\" }), {\n status: 502,\n headers: { \"Content-Type\": \"application/json\" },\n });\n }\n\n const data = await aiRes.json();\n const answer = data?.content?.[0]?.text ??\n \"Sorry, I couldn't get an answer right now.\";\n\n return new Response(JSON.stringify({ answer }), {\n headers: { \"Content-Type\": \"application/json\" },\n });\n } catch (err) {\n console.error(\"Ask endpoint error:\", err);\n return new Response(JSON.stringify({ error: \"Something went wrong\" }), {\n status: 500,\n headers: { \"Content-Type\": \"application/json\" },\n });\n }\n }\n\n const pageHtml = HTML.replace(\n /__OG_IMAGE_URL__/g,\n url.origin + \"/og-image.png\",\n );\n return new Response(pageHtml, {\n headers: { \"Content-Type\": \"text/html;
