#geocoding

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.
