How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object containing the original claim, a verdict (true/false or similar), an array of supporting evidence items, and a numeric confidence score between 0 and 1 indicating how certain the system is about the verdict.
Example use cases
Crypto price threshold check
“Is it true that Ethereum is trading above $3,500 right now? Check this claim and tell me the verdict and how confident you are.”
Macroeconomic condition verification
“Verify the claim 'The US unemployment rate is below 4%' and give me the supporting evidence and a confidence score.”
Prediction market condition resolution
“I need to resolve a bet — verify the claim 'Gold is above $2,000 per ounce today' and tell me whether it's true with evidence.”
Technical details
Endpoint
GEThttps://klymax402.com/api/event-resolver/api/verifyWhen to prefer
Choose this endpoint when you need a structured, evidence-backed verdict on a specific factual claim — especially claims about crypto prices, DeFi metrics, or macroeconomic indicators. It is ideal for automated pipelines that need a machine-readable confidence score and evidence trail rather than a free-text answer. Prefer this over a general web search when you need a normalized, JSON-structured fact-check with a clear true/false verdict.
Side effects
- Ambiguous or unverifiable claim returns low confidence or null verdict
- Claim about a very niche or unsupported data source may return empty evidence array
- Malformed or missing 'claim' parameter results in an error response
- Stale data may cause incorrect verdicts for rapidly changing metrics like live crypto prices
- Rate limiting or payment failure with x402 protocol results in 402 payment required response
