Preoracle

A prediction-market stack: we sync Polymarket data (Gamma + Dome), store it in Postgres, and expose market context and metrics (price change, volatility, volume, spread, liquidity, time to expiry). The worker also generates structured BUY/SKIP/HOLD verdicts via Gemini (generateContent). The web app is a simple chat UI that asks the backend for a market by condition_id and shows those metrics.

• Worker — Backend: syncs markets and candlesticks, serves GET /markets/:conditionId with context + metrics. Run npm run server (API), npm run sync (Gamma), npm run sync-dome (Dome cache), npm run metrics -- <condition_id>.
• Web — Next.js frontend; chat input sends requests to the worker and displays the response.

Run: In apps/worker, set DATABASE_URL, DOME_API_KEY, and GEMINI_API_KEY in .env, then npm run server. Optional: VERDICTS_LLM_TIER=high|default|lite|experimental|experimental-lite, VERDICTS_DELAY_MS=1200, TRACKED_MARKET_LIMIT=20–50. In apps/web, set WORKER_API_URL (e.g. http://localhost:4000) and npm run dev.
