boring-api · geo — Distance Matrix is a paid API for AI agents from geo.boring-api.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).
Computes a matrix of geodesic distances and bearings between multiple origin and destination coordinate pairs using pure in-Worker spatial math, with no external API calls.

How this service works
Pure-library spatial math and timezone lookup. Distance, bearing, polygons, point-in-polygon, timezone-by-coords. No external API calls — all computed in-Worker.
Output
Returns a matrix object containing pairwise computed distances (and likely bearings) between every origin and destination coordinate pair, all calculated in-Worker without external API calls. The response covers all combinations of the supplied origins and destinations arrays.
Example use cases
Example prompt
“Compute the distance matrix between these three origins — (40.7128, -74.0060), (34.0522, -118.2437), (41.8781, -87.6298) — and these two destinations — (51.5074, -0.1278) and (48.8566, 2.3522) — so I can see how far each city is from London and Paris.”
Technical details
Endpoint
POSThttps://geo.boring-api.com/distance-matrixWhen to prefer
Choose this endpoint when you need to compute distances between many pairs of coordinates in a single request without relying on Google Maps, Mapbox, or other external geocoding APIs. It is ideal for logistics, routing, or optimization tasks where you already have lat/lon coordinates and need a full N×M distance matrix computed quickly and cheaply. Prefer it over single-pair distance endpoints when you need all pairwise combinations at once.
Side effects
- Missing or malformed origins/destinations arrays returns a 400 error
- Non-numeric or out-of-range latitude/longitude values cause a validation error
- Empty origins or destinations array may return an empty matrix or error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Exceeding array size limits may cause a timeout or 413 error
