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.

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.

Every IANA time zone with its coordinates and country, enriched in real time with the current UTC offset, abbreviation, DST status and local time (computed from the system ICU time-zone database — always up to date, no key). Look up a zone by name, list all zones for a country, search zones by name, or find the nearest IANA zones to any latitude/longitude. 418 zones across 247 countries/territories. Ideal for scheduling, calendars, logistics, geo apps and any feature that needs to map a place or coordinate to the right time zone and current local time.

Convert between latitude/longitude and the Maidenhead Locator System — the grid-square "QTH locator" (like JN58td or IO91wm) used by amateur radio, APRS and contesting to describe a position compactly. The encode endpoint turns a latitude and longitude into a locator at 4-, 6-, 8- or 10-character precision. The decode endpoint turns a locator back into the centre coordinates, the south-west corner and the size of the grid square. The distance endpoint gives the great-circle distance (kilometres and miles) and bearing between the centres of two locators — the classic "how far and which way is that station". Everything is computed locally and deterministically, so it is instant and private. Ideal for amateur-radio and APRS tools, contest logging, antenna aiming, and grid-based mapping. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the Maidenhead system; for Plus Codes, MGRS, UTM and DMS use a geo-convert API and for precise geodesic distance use a geodesy API.

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.

Functional-genomics experiments as an API — powered by NCBI GEO (Gene Expression Omnibus), the largest public repository of gene-expression data. GEO archives expression series and curated datasets from microarray and high-throughput-sequencing experiments across every organism. Search experiments by keyword and optionally by organism, and look up any series or dataset to get its metadata: title, summary, assay type (expression profiling by array or by sequencing), organism, number of samples, platform and the publication behind it. From β-cell stress studies to cancer transcriptomics across human and mouse, it turns the GEO archive into a simple search-and-fetch API for transcriptomics, bioinformatics and research-data discovery. A gene-expression / functional-genomics dataset repository — distinct from sequence (ENA), variant (ClinVar, dbVar), structure (PDB) and ontology databases. Open data from NCBI GEO (public domain).

Look up the administrative subdivisions of any country — 5,300+ states, provinces, regions and districts across 229 countries, with ISO 3166-2 codes. Search by name, country or type, fetch all subdivisions of a country (perfect for address-form dropdowns), or resolve an ISO 3166-2 code like US-CA to its name, type and coordinates. Bundled, fast and always available.

Search a database of 33,000+ cities worldwide (population 15,000+) from GeoNames. Find cities by name, country and minimum population, look up a city by id, or find all cities near a coordinate (radius search). Each city includes coordinates, region, population, timezone and elevation — ideal for autocompletes, location pickers, store locators and geo dashboards.

Real-time and historical earthquake data sourced from the USGS Earthquake Hazards Program. Pull ready-made summary feeds by magnitude band and period (significant, M4.5+, M2.5+, M1.0+ or all, over the past hour, day, week or month), run a full FDSN search by time window, magnitude range and geographic radius, count matching events, fetch the latest quakes worldwide, or look up a single event by its USGS id. Every event comes as a clean record with magnitude and type, place, ISO timestamps, depth and coordinates, felt reports, shaking intensity (CDI/MMI), PAGER alert level, tsunami flag and significance. Authoritative public data delivered through a fast, reliable API — ideal for insurance and risk, IoT and sensor alerting, newsrooms, research and disaster-response apps.

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.

Terrain elevation in metres above sea level for any coordinate — a single point or a batch of up to 50 points for route and grid profiles. Ideal for hiking and outdoor apps, mapping, drone flight planning, solar siting, flood and line-of-sight analysis.
