How can I find out the IAB category for an IP address using Deno?

To determine the IAB category for an IP address using IP2Location.io in Deno, you can use the IP2Location.io API to retrieve geolocation and related data. For more info, please see the IAB categories.

  1. We'll assume that you have already installed Deno and we won't cover that here. You will also need a paid subscription to the Security plan. Subscribe now!
  2. Save the below code into a file called test.js on your computer.
    JavaScript 
    
import * as https from "node:https";

var key = "YOUR_API_KEY";
var ip = "8.8.8.8";

let url = "https://api.ip2location.io/?key=" + key + "&ip=" + ip +
  "&format=json";

let d = "";
let req = https.get(url, function (res) {
  res.on("data", (chunk) => (d = d + chunk));
  res.on("end", function () {
    if (res.statusCode == 200) {
      let data = JSON.parse(d);
      if (data.ads_category !== undefined && data.ads_category !== null) {
        console.log(
          "The IAB category for IP " + data.ip + " is " + data.ads_category +
            ".",
        );
      } else {
        console.log(
          "ERROR: The IAB category field requires a paid subscription to the Security plan.",
        );
      }
    } else if (res.statusCode == 400 || res.statusCode == 401) {
      if (d.includes("error_message")) {
        console.log("ERROR: " + JSON.parse(d).error.error_message);
      } else {
        console.log(d);
      }
    } else {
      console.log(d);
    }
  });
});

req.on("error", function (e) {
  console.log(e);
});
  3. In the command line, run the below command.
    Bash 
    
deno --allow-env --allow-net test.js

This script will output the IAB category of specified IP address. Make sure to replace 8.8.8.8 with the IP address you want and replace YOUR_API_KEY to your own API key.
