How can I determine the currency code for the IP address location using Ruby?

To determine the currency code for an IP address using IP2Location.io in Ruby, you can use the IP2Location.io API to retrieve geolocation and related data.

  1. We'll assume that you have already installed Ruby and we won't cover that here. You will also need a paid subscription to the Plus plan or higher. Subscribe now!
  2. Save the below code into a file called test.rb on your computer.
    Ruby 
    
require 'net/http'
require 'json'

key = 'YOUR_API_KEY'
ip = '8.8.8.8'

uri = URI('https://api.ip2location.io/')
params = { :key => key, :ip => ip }
uri.query = URI.encode_www_form(params)

res = Net::HTTP.get_response(uri)

if !res.body.nil?
	begin
		myobj = JSON.parse(res.body)
		if res.is_a?(Net::HTTPSuccess)
			if myobj.key? 'country'
				puts 'The currency code for IP ' + ip + ' is ' + myobj['country']['currency']['code'] + '.'
			else
				puts 'ERROR: The currency code field requires a paid subscription to the Plus plan or higher.'
			end
		else
			if res.body.include? 'error_message'
				puts 'ERROR: ' + myobj['error']['error_message']
			else
				puts 'ERROR: ' + res.body
			end
		end
	rescue JSON::ParserError
		puts 'ERROR: Invalid JSON in response.'
	end
else
	puts 'ERROR: Error calling API.'
end
  3. In the command line, run the below command.
    Bash 
    
ruby test.rb

This script will output the currency code 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.
