[IP99](https://hashnode.com/@ip99)

IP risk & geolocation API by ThreatHunter

[Oct 14](https://hashnode.com/posts/how-to-detect-visitor-country-and-currency-in-javascript-no-backend-required/6a4e3d0b923573d74ddb6eb7/comment/6acf5002ba198b3aa9d9b790)

Nice zero-backend geo trick. For anything beyond UX localization (fraud, account risk), client-only country guesses get shaky once users sit on VPNs or residential proxies.

IP99 by ThreatHunter pairs geolocation with an IP risk score and evidence\_state (active / stale / none), so you can tell “we saw proxy signals recently” vs “we’ve never seen this address.” Free lookup, no key—useful when country alone isn’t enough.
