Geocoding — entry 079 of 80
Zippopotam.us
Zippopotam.us is a free, keyless geocoding lookup for place names: given a country code and postal/zip code it returns the place name, state/region, and latitude/longitude as JSON. It runs behind Cloudflare and now serves everything over HTTPS with an open Access-Control-Allow-Origin: * header, despite older docs still linking the plain-http form.
