Event Resolver API

br0ski777/event-resolver-x402

Connects to multiple data sources to resolve whether real-world events actually happened, with confidence scores and attribution. Exposes three paid endpoints: full event resolution for prediction markets ($0.005), quick claim verification ($0.003), and crypto price threshold checks ($0.002). You'd reach for this when settling prediction market contracts, checking if Bitcoin crossed $100K, or verifying factual claims programmatically. Uses x402 protocol for pay-per-call pricing in USDC on Base L2, no API keys required. Built for automated oracle resolution on platforms like Polymarket or custom smart contracts that need objective event data with source provenance.
