        "description": "Advanced geodesy beyond the simple great circle. The vincenty endpoint computes the distance between two latitude/longitude points on the WGS84 ellipsoid using Vincenty's inverse formula — accurate to within a millimetre, far better than the spherical approximation — plus the initial and final bearings, in metres, kilometres, miles and nautical miles. The rhumb endpoint computes the rhumb-line (loxodrome) distance and the single constant compass bearing that follows it — the path you steer by holding a heading, as used in marine and air navigation. The cross-track endpoint finds how far a point lies to the left or right of a great-circle path between two points (the cross-track distance), and how far along that path it is (the along-track distance). Everything is computed locally and deterministically, so it is instant and private. Ideal for marine and aviation navigation, surveying and GIS, route analysis, and mapping. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is advanced geodesy; for simple great-circle distance, bearing, midpoint and destination use a geo-distance API and for coordinate-format conversion use a geo-convert API."
