x402
Geospatial Distance and Bearing Calculator is a paid API for AI agents from geospatial.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).
Computes the great-circle distance and initial bearing between two WGS84 lat/lon coordinates.

How this service works
Distance and initial bearing between two coordinates.
Output
Returns the great-circle (haversine or Vincenty) distance between the two coordinates (likely in kilometers or meters) and the initial compass bearing in degrees from the origin toward the destination.
Example use cases
Drone flight path planning
“I need to know the straight-line distance and compass bearing from the launch point at 37.7749° N, 122.4194° W to the target at 37.8044° N, 122.2712° W so I can plan the drone's initial heading.”
Shipping route distance estimate
“How far apart are the ports at 1.3521° N, 103.8198° E (Singapore) and 22.3193° N, 114.1694° E (Hong Kong), and what's the initial bearing for the route?”
Nearest tower signal analysis
“Calculate the distance and bearing from my base station at 51.5074° N, 0.1278° W to the relay tower at 51.4700° N, 0.4543° W so we can check if it falls within the 50km range.”
Technical details
Endpoint
POSThttps://geospatial.openverbs.com/v1/distanceWhen to prefer
Use this endpoint when you need a fast, cheap ($0.002/call) programmatic computation of point-to-point geodesic distance and bearing from raw coordinates, without needing routing, roads, or address geocoding. Prefer it over full mapping APIs when you already have lat/lon values and just need the angular and linear relationship between two points.
Side effects
- Latitude or longitude out of valid range (lat: -90 to 90, lon: -180 to 180) returns a validation error
- Missing required 'from' or 'to' fields causes a 400 bad request
- Identical origin and destination may return distance 0 and undefined or null bearing
- Network timeout or service unavailability returns a 5xx error
- Payment failure via x402 protocol results in a 402 Payment Required response
