Geocoding — entry 048 of 80
keycdn IP Location Finder
KeyCDN's IP geolocation lookup is a free, no-signup JSON endpoint gated not by a key but by a special User-Agent header naming a site that must carry a KeyCDN backlink, rate-limited to 3 requests per second. It has no CORS support, so it can't be called directly from browser JavaScript on a third-party origin.
