API USAGE

4VIO API is very easy to use. It saves time for dealing with your own code, rather than dealing with API-related issues. All you have to do is determine what you want to do with the answer from the API you are using.

CODE SAMPLES

Bash

#!/bin/bash

ip=$(curl -s https://api.4vio.com/ip/v1)
echo "IP: $ip"

C#

using System;
using System.Net;

namespace ipapi.Examples {
    class Program {
        public static void Main (string[] args) {
            WebClient webClient = new WebClient();
            string publicIp = webClient.DownloadString("https://api.4vio.com/ip/v1");
            Console.WriteLine("IP: {0}", publicIp);
        }
    }
}

Go

package main

import (
        "io/ioutil"
        "net/http"
        "os"
)

func main() {
        res, _ := http.Get("https://api.4vio.com/ip/v1")
        ip, _ := ioutil.ReadAll(res.Body)
        os.Stdout.Write(ip)
}

Java

try (java.util.Scanner s = new java.util.Scanner(new java.net.URL("https://api.4vio.com/ip/v1").openStream(), "UTF-8").useDelimiter("\\A")) {
    System.out.println("IP " + s.next());
} catch (java.io.IOException e) {
    e.printStackTrace();
}

Javascript

<script type="application/javascript">
  function GetIP(json) {
    document.write("IP: ", json.ip, " - Country: ", json.ip_country);
  }
</script>

<script type="application/javascript" src="https://api.4vio.com/ip/v1/jsonp"></script>

jQuery

<script type="application/javascript">
  $(function() {
    $.getJSON("https://api.4vio.com/ip/v1/jsonp",
      function(json) {
        document.write("IP: ", json.ip);
      }
    );
  });
</script>

Lisp

;This example requires the drakma http package installed.
;It can be found here: http://www.weitz.de/drakma

(let ((stream
    (drakma:http-request "https://api.4vio.com/ip/v1" :want-stream t)))
  (let ((public-ip (read-line stream)))
    (format t "IP: ~A" public-ip)))

Lua

http.Fetch("https://api.4vio.com/ip/v1", function(body) print("IP: " .. body ) end

Objective-C

NSURL *url = [NSURL URLWithString:@"https://api.4vio.com/ip/v1"];
NSString *ipAddress = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
NSLog(@"IP: %@", ipAddress);

Scala

val addr = scala.io.Source.fromURL("https://api.4vio.com/ip/v1").mkString
println(s"IP: $addr")

Perl

use strict;
use warnings;
use LWP::UserAgent;

my $ua = new LWP::UserAgent();
my $ip = $ua->get('https://api.4vio.com/ip/v1')->content;
print 'IP: '. $ip;

PHP

ip = get('https://api.4vio.com/ip/v1').text
print('IP: {}'.format(ip))

require "net/http"

ip = Net::HTTP.get(URI("https://api.4vio.com/ip/v1"))
puts "IP: " + ip
