A simple to integrate Geolocation API that provides information about your users, either directly from a browser or device, or from any of your servers.
Provides data such as City, Region, Postal code, Country, Continent, Coordinates, Timezone, Currency, Organization, ISP, AS, if they are using a mobile network, or an anonymous proxy/VPN.
Works with IPv4, IPv6 or hostnames. Supports batch requests with up to 100 queries per HTTP request.
The free version requires no sign up or keys, and it's limited to 45 HTTP requests per minute from an IP address. Non-commercial use only.
The pro service includes more features such as SLA for 99.9% of monthly uptime, a dashboard with usage statistics, up to 10 API keys (customizable with restrictions), and more.
Predax is a real-time IP intelligence platform that detects VPN, proxy, Tor, and datacenter traffic with risk scoring from 0-100. Every lookup returns a full threat profile โ classification flags, geolocation, ASN data, network info, and a transparent provenance breakdown showing exactly why an IP was flagged.
Built for developers and site owners who need control over their traffic. Integrate via REST API with a single header, or install our free WordPress and WooCommerce plugins for one-click protection with no code required.

Predax's answer:
IPSentry is used by WordPress site owners, WooCommerce stores, and developers across multiple countries. As a privacy-focused company, we don't publicly disclose customer names without their permission.
Predax's answer:
IPSentry started from a personal frustration. I was running content sites monetised with Google AdSense, and kept getting hammered by waves of VPN and proxy traffic. This non-genuine traffic was dragging down my overall RPM โ advertisers don't pay premium rates when their ads are being served to masked, unverifiable visitors. My revenue was suffering and I had no visibility into what was hitting my sites.
I wanted control over my traffic. I wanted to see exactly who was visiting, filter out the junk, and make informed decisions about what to allow and what to block. I looked for a WordPress plugin that could do this โ detect VPN and proxy visitors, flag them, let me decide what to do โ and found nothing that actually worked. The few options that existed were either broken, absurdly expensive, or required wiring up an external API with custom code.
So I built my own. It started as a simple IP lookup tool, then grew into a full detection API with VPN, proxy, Tor, and datacenter identification. I added a WordPress plugin so any site owner could install it in one click and immediately see and control their traffic, then a WooCommerce plugin for fraud prevention at checkout.
The Community Threat Network came next โ the idea that when one site blocks a bad actor, every other IPSentry user benefits from that intelligence. Today IPSentry protects sites across multiple countries with millions of IP lookups per month.
Predax's answer:
IPSentry combines real-time IP intelligence with community-powered threat detection โ something no other provider offers at this price point.

Free public geo APIs do not love datacenter traffic. My first instinct was to use ip-api.com โ itโs the go-to for โwhat country is this IPโ lookups and has a generous free tier. Hooked it up, ran the direct profile, got a clean response. Then I ran it through the Bright Data proxies I had (these) and got a HTTP 402. Turns out ip-api.comโs free tier detects any datacenter egress and refuses to serve it. The proxy... - Source: dev.to / 2 months ago
The original version used http://ip-api.com โ plain HTTP. On a cloud server, that traffic is unencrypted and could be intercepted and spoofed. I switched to https://ipinfo.io which supports HTTPS on the free tier. - Source: dev.to / 5 months ago
In this example, I'll process messages based on their originating IP address. Multiple threads will enrich them with location data fetched from the public API at https://ip-api.com/. - Source: dev.to / 8 months ago

The Language may be different: You can check up the [Set language based on IP], and make the system automatically set up the browser language according to the IP that you set up. Mismatch of DNS or system time: We recommend you to replace the proxy IP and start the operation. Or you can enter the site https://ip-api.com for verification. Source: over 2 years ago
