Get a Replicate API token at https://replicate.com/account/api-tokens\n2. Add it as an environment variable: `REPLICATE_API_TOKEN`\n\n## HTTP API\n\n**Endpoint:** `GET /`\n\n| Param | Default | Description |\n|-------|---------|-------------|\n| `lat` | `40.7128` | Latitude |\n| `lon` | `-74.006` | Longitude |\n| `location` | `New York` | Location name (used in prompt) |\n| `format` | `json` | `json` or `html` |\n\n### Examples\n\n```\n# JSON response (default)\nGET /?location=Tokyo&lat=35.6762&lon=139.6503\n\n# HTML page with rendered image\nGET /?location=Paris&lat=48.8566&lon=2.3522&format=html\n```\n\n## Cron\n\n`cron.ts` runs on a schedule (configure in Val Town UI) and stores the latest result in blob storage under the key `weather-art-latest`.\n\n## Files\n\n- `main.ts` — HTTP handler (entrypoint)\n- `cron.ts` — Interval/cron handler\n- `shared/weather.ts` — Open-Meteo API client\n- `shared/prompt.ts` — Weather → image prompt builder\n- `shared/replicate.ts` — Replicate SDXL client\n",[174],"2a9b8a2a-3a8a-11f1-a162-42b51c65c3df","shared","bc1fb6c1-dfd1-45ff-82e2-881df219f79f",1,["D",1776450051976],"directory",[181],"pulls","branches","forks","envVars",{"_194":183,"_196":61},"connections",{"_194":61,"_195":61},"count","unfilledCount","emptyCount",{"_41":180,"_31":181,"_29":182,"_135":-5,"_39":40,"_38":183,"_137":57,"_36":255,"_13":61,"_32":185,"_34":-5,"_23":24,"_139":-5,"_209":256,"_26":257},{"_41":246,"_31":247,"_29":248,"_135":182,"_39":40,"_38":249,"_137":24,"_36":250,"_13":251,"_32":33,"_34":252,"_23":24,"_139":-5,"_209":253,"_26":254},{"_41":237,"_31":238,"_29":239,"_135":182,"_39":40,"_38":240,"_137":24,"_36":241,"_13":242,"_32":33,"_34":243,"_23":24,"_139":-5,"_209":244,"_26":245},{"_41":230,"_31":231,"_29":232,"_135":182,"_39":40,"_38":183,"_137":57,"_36":233,"_13":61,"_32":33,"_34":234,"_23":24,"_139":-5,"_209":235,"_26":236},{"_41":173,"_31":174,"_29":175,"_135":-5,"_39":40,"_38":176,"_137":57,"_36":227,"_13":61,"_32":20,"_34":178,"_23":24,"_139":-5,"_209":228,"_26":229},{"_41":164,"_31":165,"_29":166,"_135":-5,"_39":40,"_38":167,"_137":57,"_36":224,"_13":169,"_32":170,"_34":171,"_23":24,"_139":-5,"_209":225,"_26":226},{"_41":156,"_31":157,"_29":55,"_135":-5,"_39":40,"_38":158,"_137":24,"_36":221,"_13":160,"_32":161,"_34":162,"_23":24,"_139":-5,"_209":222,"_26":223},{"_41":150,"_31":151,"_29":152,"_135":-5,"_39":40,"_38":153,"_137":57,"_36":218,"_13":61,"_32":33,"_34":35,"_23":24,"_139":-5,"_209":219,"_26":220},{"_41":147,"_31":27,"_29":30,"_135":-5,"_39":40,"_38":14,"_137":57,"_36":215,"_13":61,"_32":33,"_34":35,"_23":24,"_139":-5,"_209":216,"_26":217},{"_41":141,"_31":142,"_29":143,"_135":-5,"_39":40,"_38":144,"_137":57,"_36":212,"_13":61,"_32":33,"_34":35,"_23":24,"_139":-5,"_209":213,"_26":214},{"_41":132,"_31":133,"_29":134,"_135":-5,"_39":40,"_38":136,"_137":57,"_36":208,"_13":61,"_32":33,"_34":35,"_23":24,"_139":-5,"_209":210,"_26":211},["D",1776729110811],"children",[],[133],["D",1776727857669],[],[142],["D",1776729146204],[],[27],["D",1776727857040],[],[151],["D",1776457556103],[],[157],["D",1776454939962],[],[165],["D",1776450102868],[],[174],"2a9b5f14-3a8a-11f1-a162-42b51c65c3df","weather.ts","2a9b5fc8-3a8a-11f1-a162-42b51c65c3df",["D",1776450051976],"// Fetches current weather from Open-Meteo (free, no API key needed)\n\nexport interface WeatherData {\n temperature: number; // °C\n windSpeed: number; // km/h\n humidity: number; // %\n weatherCode: number;\n isDay: boolean;\n cloudCover: number; // %\n precipitation: number; // mm\n latitude: number;\n longitude: number;\n locationName: string;\n}\n\n// WMO Weather interpretation codes → human descriptions\nconst WEATHER_CODES: Record = {\n 0: \"clear sky\",\n 1: \"mainly clear\",\n 2: \"partly cloudy\",\n 3: \"overcast\",\n 45: \"foggy\",\n 48: \"depositing rime fog\",\n 51: \"light drizzle\",\n 53: \"moderate drizzle\",\n 55: \"dense drizzle\",\n 56: \"light freezing drizzle\",\n 57: \"dense freezing drizzle\",\n 61: \"slight rain\",\n 63: \"moderate rain\",\n 65: \"heavy rain\",\n 66: \"light freezing rain\",\n 67: \"heavy freezing rain\",\n 71: \"slight snowfall\",\n 73: \"moderate snowfall\",\n 75: \"heavy snowfall\",\n 77: \"snow grains\",\n 80: \"slight rain showers\",\n 81: \"moderate rain showers\",\n 82: \"violent rain showers\",\n 85: \"slight snow showers\",\n 86: \"heavy snow showers\",\n 95: \"thunderstorm\",\n 96: \"thunderstorm with slight hail\",\n 99: \"thunderstorm with heavy hail\",\n};\n\nexport function describeWeatherCode(code: number): string {\n return WEATHER_CODES[code] ??
