UK Postcode API
UK postcode and geography lookup as an API, built on the open postcodes.io dataset. Resolve any UK postcode to its latitude/longitude and full administrative hierarchy — district, ward, county, parish, parliamentary constituency, region, NHS health authority and statistical areas (LSOA, MSOA). Validate a postcode, reverse-geocode coordinates to the nearest postcodes (with distance), find postcodes near a given one, autocomplete a partial postcode for address forms, look up an outcode (the first half, e.g. SW1A) and fetch a random postcode. Real data, no key needed upstream. Ideal for checkout and address forms, delivery and logistics, store locators, and UK geo-analytics.

Postal Code API
Resolve postal and ZIP codes to city, state and geo-coordinates for around 60 countries — and the reverse, listing all postal codes of a city. Perfect for checkout and address-form autofill, shipping, store locators and geo-targeting.

Weather API
Real-time weather: current conditions, multi-day forecast, historical weather, marine/wave forecast, astronomy (sun/UV), air quality, geocoding and timezone.

GeoJSON API
Measure GeoJSON geometry on the surface of the earth. Compute the true area of a Polygon or MultiPolygon (in square metres, square kilometres, hectares, acres and square miles), find the centroid of any GeoJSON, get the bounding box (west/south/east/north) and its centre, measure the length of a LineString or MultiLineString (in kilometres, metres, miles and nautical miles), and test whether a latitude/longitude point falls inside a polygon. Accepts geometries, Features and FeatureCollections; coordinates follow the GeoJSON [longitude, latitude] order. Perfect for mapping apps, geofencing, territory and catchment analysis, route distances and spatial dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 6 endpoints. Distinct from abstract shape geometry, coordinate-format conversion, slippy map tiles and administrative-boundary data.
