Getting started with the rest-client gem - QuotaGuard Static
Integrating with the rest-client gem is a one-liner. This will print out one of your QuotaGuard Static IPs:
require 'rest-client'
RestClient.proxy = ENV['QUOTAGUARDSTATIC_URL'] if ENV['QUOTAGUARDSTATIC_URL']
res = RestClient.get('http://ip.jsontest.com')
puts "Your IP was: #{res.body}"
