Tracking DevFinanceTools since Aug 2026.
Free public geo APIs do not love datacenter traffic. My first instinct was to use ip-api.com — it’s the go-to for “what country is this IP” lookups and has a generous free tier. Hooked it up, ran the direct profile, got a clean response.... - Source: dev.to / 4 months ago
The original version used http://ip-api.com — 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 / 7 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 / 9 months ago
