Geo Distance API

healthy 3,497 Subscribers

Great-circle (as-the-crow-flies) navigation maths between latitude/longitude points. The distance endpoint returns the straight-line distance in metres, kilometres, miles and nautical miles, plus the initial and final compass bearing and the nearest 16-point compass direction. The destination endpoint computes where you end up from a start point, a bearing and a distance, and the midpoint endpoint finds the great-circle midpoint between two points. Perfect for proximity and radius search, geofencing, flight and shipping estimates, "distance from me" features and mapping. Pure local computation — no key, no third-party service, instant. These are straight-line distances on a spherical earth, not road routes. Live, nothing stored. 4 endpoints. Distinct from road routing, GeoJSON geometry measurement and coordinate-format conversion.

Geo Distance API — oanor API marketplace

Geo Distance API

A fast, fully-local great-circle geospatial toolkit: compute the haversine distance between two coordinates (in km, m, miles or nautical miles), the initial and final compass bearing, the geographic midpoint, the destination point reached from an origin on a bearing at a given distance, and a bounding box around a center for a radius. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for logistics, delivery and fleet apps, store locators, real-estate search, travel and mapping tools.

 Routing API — oanor API marketplace

Routing API

Driving routes with distance, duration and geometry, distance/duration matrices for up to 25 points, and nearest-road snapping — on the global OpenStreetMap road network. Coordinates are simple lat,lon pairs.

 OpenStreetMap Community API — oanor API marketplace

OpenStreetMap Community API

Live OpenStreetMap community and contribution data as an API — the people and the edits behind the collaborative free world map, served from the official OSM API. Look up any mapper by their user id for their profile (display name, account age, total changesets and GPS traces, roles), pull a user's recent changesets — each edit batch with its comment, the editor used, and how many map features it created, modified or deleted — or read the open and resolved map notes, the community feedback pins, inside a geographic bounding box. The OSM contributor-and-edits layer for mapping, community and dashboard apps. Live, no key. Distinct from geocoding, routing and map-tile APIs that merely consume OpenStreetMap data — this is the OSM community and editing activity itself.

 Meteorites API — oanor API marketplace

Meteorites API

NASA's catalogue of 45,000+ meteorites recovered on Earth as an API. For each meteorite: its name, NASA id, classification (recclass, e.g. L5, Iron), mass in grams, whether it was seen to fall or simply found, the year, and the latitude/longitude where it was recovered. Look one up by name or id, find the meteorites NEAR any coordinate (great-circle distance), rank by mass or year, list a classification or year, or search. Great for space, education, mapping and museum apps. Distinct from asteroids and close-approach data — these are rocks already on the ground.
