How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
Returns a JSON object with a boolean ok field and computed values including the geodesic distance between the two coordinate pairs and the compass bearing from point 1 to point 2, likely expressed in kilometers and degrees respectively.
Example use cases
Drone delivery range check
“I need to know the distance and bearing from our warehouse at 51.5074° N, 0.1278° W to a delivery address at 51.4700° N, 0.4543° W — can you calculate that for me?”
Ship navigation heading
“Calculate the geodesic distance and bearing from the port of Rotterdam at 51.9244° N, 4.4777° E to the port of New York at 40.6640° N, 74.0049° W so I can plan the ship's route.”
Geofencing radius validation
“How far is the customer's location at 48.8566° N, 2.3522° E from our Paris store at 48.8738° N, 2.2950° E, and in what direction — I want to check if they're within a 5 km service radius?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/geo_distance_bearing?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call geospatial computation with no API key or signup — ideal for AI agents needing one-off or low-volume distance/bearing calculations paid in USDC via x402. Prefer over self-hosted solutions when infrastructure overhead is undesirable, and over mapping APIs when you only need raw geodesic math without map rendering or routing.
Side effects
- Latitude out of range (-90 to 90) returns validation error
- Longitude out of range (-180 to 180) returns validation error
- Missing required coordinate fields (lat1, lon1, lat2, lon2) returns 400-level error
- Payment failure or insufficient USDC balance returns HTTP 402
- Identical coordinates may return zero distance and undefined or zero bearing
