Summary
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.

Event Resolver API
Resolve real-world events for prediction market settlement. Aggregates data from multiple sources to determine if an event occurred, with confidence scores and source attribution.

|---|---|---|---|
/api/resolve | POST | $0.005 | Full event resolution with confidence score and sources |
/api/verify | POST | $0.003 | Quick-verify a factual claim (true/false/unverifiable) |
/api/price-check | POST | $0.002 | Check if crypto price crossed a threshold |
