| ● | Polymarket Liquidity Authenticity + UMA Resolution-Risk | ◦ | Per-market liquidity authenticity + UMA resolution-risk for Polymarket prediction markets, sold to AI trading agents via x402 ($0.20/call, USDC on Base). Returns whether apparent volume is broad/organic or concentrated/manufactured (HHI, effective traders, book cross-check, on-chain counterparties) AND the UMA resolution-risk on two axes: how often a category disputes on UMA x when disputed, how often the result FLIPS the original proposal vs just confirms, plus whether the criterion is objective (checkable) or subjective. Dispute-rate and flip-rate often invert by category - a two-axis read no other tool gives. Fact/base-rate, never a wash verdict nor per-market prediction. Also two /market-authenticity/{conditionId} and /x402-authenticity/{payTo} parameterized endpoints (see /openapi.json). | Data | 3 | $0.05 | 100.00%25 chk | $4 | 6 | BSE |
