Congrats on the launch and the HN coverage @jonathan-kosgei! Looks very similar to my service, https://ipinfo.io:

    $ curl ipinfo.io/8.8.8.8
    {
      "ip": "8.8.8.8",
      "hostname": "google-public-dns-a.google.com",
      "city": "Mountain View",
      "region": "California",
      "country": "US",
      "loc": "37.3860,-122.0840",
      "org": "AS15169 Google LLC",
      "postal": "94035",
      "phone": "650"
    }

It also started as a simple geolocation API when I first launched it over 3 years ago. Since then we've built many custom data sets and expanded to more products, including IP to company details, carrier detection, reverse IP hosting data and more. See https://ipinfo.io/products. We've been lucky enough to signup customers like Dell, Tesla, eBay, TripAdvisor, Plesk and others. Happy to chat and share notes at some point!
