Geocoding — entry 049 of 80
Kiprio UK Postcode
Kiprio's UK Postcode API resolves a postcode to latitude/longitude plus a full slice of UK administrative geography — region, county, district, ward, Westminster constituency, LSOA/MSOA, and IMD deprivation data — over a single GET endpoint gated by an X-API-Key header. It's one of dozens of small HTTP APIs sharing one Kiprio account and a genuine free tier (1,000 requests/month, no card) before paid Pro/Business tiers kick in.
