How this service works
Computes straight-line haversine distance and compass bearing between any two latitude/longitude points, returned in km, miles, and nautical miles. Useful for geofencing checks, travel-time estimation inputs, and mapping agents working from raw coordinate pairs rather than place names.
Output
Returns the haversine (great-circle) straight-line distance between the two coordinate pairs expressed in kilometers, miles, and nautical miles, along with the compass bearing from point 1 to point 2.
Example use cases
Example prompt
“What's the straight-line distance and compass bearing between coordinates 40.7128, -74.0060 and 51.5074, -0.1278? Give me the result in km, miles, and nautical miles.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/coordinates-distanceWhen to prefer
Use this endpoint when you have raw latitude/longitude coordinate pairs and need fast, accurate straight-line distance and bearing calculations without geocoding overhead. Ideal for geofencing checks, routing pre-filters, travel-time estimation inputs, or any mapping agent that already has coordinates rather than place names.
Side effects
- Missing or malformed lat/lon values result in a validation error
- Out-of-range coordinate values (e.g. lat outside -90 to 90) may cause errors
- Non-numeric strings passed for coordinate fields will fail parsing
- Identical coordinates may return zero distance and undefined or zero bearing
- Payment failure or insufficient USDC balance returns a 402 error
