How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing the model used for the calculation ('mean-radius sphere') and the computed distance between the two coordinate pairs expressed in meters as a floating-point number.
Example use cases
Delivery radius eligibility check
“Can you tell me the distance in meters between our warehouse at 51.5074° N, 0.1278° W and a customer at 51.6214° N, 0.1546° W so I can check if they're within our 20km delivery zone?”
Nearest store location ranking
“I need the distance in meters between my current position at 48.8566° N, 2.3522° E and a store located at 48.8738° N, 2.2950° E — I'm building a nearest-store finder.”
Geofence boundary distance check
“Calculate the distance in meters from coordinates 37.7749° N, 122.4194° W to 37.8044° N, 122.2712° W so I can verify whether a reported event falls outside my geofence perimeter.”

Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/geometry/distance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, accurate great-circle distance computation between two coordinate pairs and want a simple metered API with per-call micropayment pricing via x402. It is best suited for single point-pair distance lookups rather than bulk routing or multi-waypoint navigation. Prefer it over full mapping APIs when you only need raw distance (not routes, turn-by-turn directions, or place lookups).
Side effects
- Missing or invalid lat/lon values outside -90 to 90 (lat) or -180 to 180 (lon) ranges return validation errors
- Payment failure or insufficient USDC balance may block the request under x402 protocol
- Malformed JSON body returns a parsing error
- Identical coordinates for both points return a distance of 0 meters (valid but may indicate a caller error)
