Earthquake API

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.

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.

Exercises API

A complete exercise and workout database covering 870+ exercises: search and filter by target muscle, required equipment, category, difficulty level, force type and mechanic, fetch a single exercise with step-by-step instructions, primary and secondary muscles and demonstration images, pull a random exercise matching any filter, and read all available facet values to build filter UIs. Every endpoint accepts input via the query string or the request body and returns lean, predictable JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for fitness and gym apps, workout planners, personal-trainer tools and health platforms.

Every endpoint accepts input via the query string or the request body and returns lean, predictable JSON with normalized address, coordinates, phone and website fields. Ideal for beer and travel apps, store locators, maps and directory features.
