x402-toolbox Geo Distance Between Coordinates
x402
x402-toolbox Geo Distance Between Coordinates is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).
Calculates the straight-line (geodesic) distance between two geographic coordinate pairs, paid per call via x402/USDC on Base.

How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with a computed distance value between the two provided coordinate pairs, along with confirmation that the payment was accepted (ok: true, paid: true). The distance is expressed in a standard unit (likely kilometers or meters).
Example use cases
Flight path distance estimator
“Calculate the straight-line distance between Los Angeles (34.0522° N, 118.2437° W) and Tokyo (35.6762° N, 139.6503° E) in kilometers so I can estimate flight time.”
Delivery radius checker
“How far apart are coordinates 37.7749° N, 122.4194° W and 37.8044° N, 122.2712° W? I need to know if a delivery address falls within a 15-mile radius of our warehouse.”
Nearest store proximity check
“Give me the distance between 48.8566° N, 2.3522° E (Paris headquarters) and 48.8738° N, 2.2950° E (candidate store location) so I can see if they're too close to each other.”

Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/geo/distance-between-coordinates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-signup, pay-per-call geodesic distance computation between two coordinate pairs and are already operating within the x402/USDC payment ecosystem. It is ideal for AI agents that need to avoid API key management and want micropayment-based access. Prefer it over full geocoding APIs when you already have coordinates and only need the distance metric.
Side effects
- Missing or malformed latitude/longitude inputs return an error
- Coordinates out of valid range (-90 to 90 lat, -180 to 180 lon) may produce errors
- Payment failure via x402 (insufficient USDC balance) results in a 402 response and no computation
- Worker cold-start or timeout on Cloudflare edge may produce a 5xx error
- Schema parameter passed incorrectly may yield unexpected results
