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.

What It Does / Endpoints

Endpoint	Method	Price	Description
`/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

Use Cases

Prediction market settlement -- Automated oracle for resolving binary, numeric, and categorical outcomes on-chain
Fact checking -- Quick verification of claims with confidence scores and source attribution
Price monitoring -- Check if crypto assets crossed key price thresholds for contract settlement
Event tracking -- Determine if real-world events (elections, sports, policy changes) occurred
On-chain resolution -- Provide objective data for HIP-4, Polymarket, or custom smart contract settlement

  "mcpServers": {
    "event-resolver": {
      "url": "https://event-resolver-production.up.railway.app/sse"
    }
  }
