$ curl 'https://api.userfeeds.io/ranking/feed;context=ethereum:0x06012c8cf97bead5deae237070f9587f8e7a266d:134330'
{"items":[{"about":null,"abouted":[],"author":"0x6be450972b30891b16c8588dcbc10c8c2aef04da","context":"ethereum:0x0...

In JavaScript (browser)

<!DOCTYPE html>
<html>
<head>
  <title>Simple ranking for Ethereum:</title>
</head>
<body>
  <script>
    fetch('https://api.userfeeds.io/ranking/cryptopurr_feed;context=ethereum:0x06012c8cf97bead5deae237070f9587f8e7a266d:134330')
    .then(function(response) {
      return response.json();
    })
    .then(function(ranking) {
      var div = document.getElementById('ranking');

      for (var i = 0; i < ranking.items.length; i++) {
        var item = ranking.items[i];
        div.innerHTML += i.toString() + '. ' + item.target.id + '<br/>';
      }
    });
  </script>
  <h1>Simple ranking for Ethereum</h1>
  <div id="ranking"></div>
</body>
</html>

In JavaScript (node.js)

const https = require('https');

const options = {
  hostname: 'api.userfeeds.io',
  port: 443,
  path: '/ranking/cryptopurr_feed;context=ethereum:0x06012c8cf97bead5deae237070f9587f8e7a266d:134330',
  method: 'GET'
};

console.log('Simple ranking for Ethereum:\n')

const req = https.request(options, (res) => {
  let data = "";

  res.setEncoding('utf8');
  res.on('data', (chunk) => {
    data += chunk;
  });
  res.on('end', () => {
    let ranking = JSON.parse(data);
    for (let index in ranking.items) {
      console.log(`${index}. ${ranking.items[index].target.id}`);
    }
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.end();


// Simple ranking for Ethereum:
//
// 0. http://example.com/one
// Score: 123.1234324
//
// 1. http://example.com/two
// Score: 32.234542343

In python

import requests

RANKING_URL = "https://api.userfeeds.io/ranking/cryptopurr_feed;context=ethereum:0x06012c8cf97bead5deae237070f9587f8e7a266d:134330"

response = requests.get(RANKING_URL).json()

print("Simple ranking for Ethereum:\n")

for index, item in enumerate(response['items']):
    print("{0}. {1}".format(index, item["target"]["id"]))
    print()
