How this service works
Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.
Output
Returns a JSON object with the great-circle distance in kilometers and miles, the origin and destination coordinate arrays, and the calculation method used (haversine). Example: {km: 5570.23, miles: 3461.179, from: [40.7128, -74.006], to: [51.5074, -0.1278], source: 'haversine'}.
Example use cases
Example prompt
“What's the straight-line distance between New York City (40.7128, -74.0060) and London (51.5074, -0.1278) in both kilometers and miles?”
Technical details
Endpoint
GEThttps://api.gocreativeai.com/v1/calc/distance/%7Barg%7DWhen to prefer
Use this endpoint when you need a quick, accurate great-circle (as-the-crow-flies) distance between two lat/lon coordinate pairs and want a simple numeric result in both km and miles without needing routing or road-based distance. Ideal for geospatial calculations in agent workflows where no API key setup is desired and pay-per-call USDC micropayment via x402 is acceptable.
Side effects
- Invalid coordinate format — coordinates must be provided as 'lat1,lon1,lat2,lon2' in the path argument
- Out-of-range coordinate values (latitude outside -90 to 90, longitude outside -180 to 180)
- Missing or malformed input query parameter resulting in 400 error
- Payment failure via x402 if USDC balance insufficient
