boring-api · geo — Bearing is a paid API for AI agents from geo.boring-api.com, paid per call via x402, $0.0005/call, status unknown (last checked 2026-09-13).
Computes the compass bearing (initial heading angle) between two geographic coordinates 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 JSON object containing the computed bearing angle in degrees (0–360), representing the initial compass heading from the 'from' coordinate to the 'to' coordinate, calculated entirely in-Worker without any external API calls.
Example use cases
Drone flight path heading
“I need to know the initial compass heading my drone should fly from its launch point at 37.7749° N, 122.4194° W (San Francisco) to its destination at 34.0522° N, 118.2437° W (Los Angeles). Can you calculate that bearing angle for me?”
Ship navigation azimuth check
“Our vessel is departing from Southampton (50.9097, -1.4044) and heading to New York (40.7128, -74.0060). What's the initial compass bearing we should set for that transatlantic route?”
Hiking trail direction finder
“I'm standing at the trailhead at coordinates 36.4864, -118.5658 and need to reach the summit at 36.5785, -118.2923. What compass heading should I walk toward to go in the right direction?”
Technical details
Endpoint
POSThttps://geo.boring-api.com/bearingWhen to prefer
Choose this endpoint when you need a fast, cheap, serverless bearing/heading computation with no third-party API dependency or rate limits. Ideal for agents that need real-time directional math embedded in a workflow without managing geospatial libraries. Prefer over full mapping APIs (Google Maps, Mapbox) when you only need the bearing angle and want predictable $0.0005 per-call pricing.
Side effects
- Missing or malformed 'from' or 'to' coordinate objects — likely returns a 400 or validation error
- Coordinates outside valid lat/lon ranges (lat > 90, lon > 180) may produce incorrect results or errors
- Payment not included or insufficient — returns HTTP 402 requiring x402 payment of $0.0005 USDC
- Identical 'from' and 'to' points may return undefined or zero bearing
- Non-numeric latitude/longitude values causing parse failures
