Polymarket cross-category scanner for AI trading agents. Scans open markets in one category (crypto, economics, geopolitics, politics, sports, esports, entertainment, weather, ai-tech) against CLOB microstructure, whale positioning, base rates, and category intelligence layers; returns ranked value opportunities with our probability vs the market price. Requires ?category=. Optional ?horizon=short|mid|long tunes which intelligence layers lead. Never charged for an empty scan.
