I subscribed to the IP Geolocation API and are using it daily in our web app to detect users from different continents. I like how easy it is to integrate it and I also love the "Live Test" option straight from the dashboard. I could immediately see the results I'd get before even subscribing. The actual integration in our product was also as simple as copy-pasting the provided code example, straight from the Dashboard.

Also, initially I had mistakenly subscribed to a different API product which I didn't need. Once I contacted support I got almost immediate reply and was issued a refund immediately. Review collected by and hosted on G2.com.

It can possibly have a somewhat better UX when it comes to allowing users to subscribe to a specific API product. Since they have a lot of different APIs with different names (which is amazing by itself), it may sometimes become confusing for someone which product are they looking at on the screen. This is how I mistakenly subscribed to a different product, but like I mentioned, I got an almost immediate refund. Review collected by and hosted on G2.com.
