Domain Age API Code Examples

PHP Code Example

Basic PHP example using cURL. We will get domain age for the domain name “whoapi.com”.

<?php

$apiKey = "demokey";
$domain = "whoapi.com";

$url = "http://api.whoapi.com/?domain=" . urlencode($domain) . "&r=domainage&apikey=" . $apiKey;

// Initialize cURL
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute request
$response = curl_exec($ch);

// Check for cURL errors
if (curl_errno($ch)) {
    die("cURL error: " . curl_error($ch));
}

curl_close($ch);

// Decode JSON response
$data = json_decode($response, true);

// Handle API response
if ($data["status"] === 0) {
    echo "Domain: " . $data["domain_name"] . "<br>";
    echo "Registered: " . ($data["registered"] ? "Yes" : "No") . "<br>";
    echo "Created: " . $data["date_created"] . "<br>";
    echo "Expires: " . $data["date_expires"] . "<br>";
    echo "Updated: " . $data["date_updated"] . "<br>";
    echo "Age (days): " . $data["age_in_days"] . "<br>";
    echo "Age (years): " . $data["age_in_years"] . "<br>";
    echo "Requests remaining: " . $data["_requests_available"] . "<br>";
} else {
    echo "API Error: " . $data["status_desc"];
}

?>

Javascript Code Example

We will get a domain age for the domain name “whoapi.com”.

const url = "http://api.whoapi.com/?domain=whoapi.com&r=domainage&apikey=demokey";

fetch(url)
  .then(response => response.json())
  .then(data => {
    if (data.status === 0) {
      console.log("Domain:", data.domain_name);
      console.log("Registered:", data.registered);
      console.log("Created:", data.date_created);
      console.log("Expires:", data.date_expires);
      console.log("Age (days):", data.age_in_days);
      console.log("Age (years):", data.age_in_years);
      console.log("Requests remaining:", data._requests_available);
    } else {
      console.error("API Error:", data.status_desc);
    }
  })
  .catch(error => console.error("Request failed:", error));

Ruby Code Example

We will get domain age for the domain name “whoapi.com”.

require 'net/http'
require 'json'
require 'uri'

url = URI("http://api.whoapi.com/?domain=whoapi.com&r=domainage&apikey=demokey")

response = Net::HTTP.get(url)
data = JSON.parse(response)

if data["status"] == 0
  puts "Domain: #{data["domain_name"]}"
  puts "Registered: #{data["registered"]}"
  puts "Created: #{data["date_created"]}"
  puts "Expires: #{data["date_expires"]}"
  puts "Updated: #{data["date_updated"]}"
  puts "Age (days): #{data["age_in_days"]}"

  puts "API Error: #{data["status_desc"]}"
end

Python Code Example

We will get domain age for the domain name “whoapi.com”. Naturally, don’t forget to add your API key.

import requests

url = "http://api.whoapi.com/"
params = {
    "domain": "whoapi.com",
    "r": "domainage",
    "apikey": "demokey"
}

response = requests.get(url, params=params)
data = response.json()

if data["status"] == 0:
    print("Domain:", data["domain_name"])
    print("Registered:", data["registered"])
    print("Created:", data["date_created"])
    print("Expires:", data["date_expires"])
    print("Updated:", data["date_updated"])
    print("Age (days):", data["age_in_days"])

    print("Requests remaining:", data["_requests_available"])
else:
    print("API Error:", data["status_desc"])

Java Code Example

We will get the domain age for the domain name “whoapi.com”. Instead of demokey you need to type your API key.

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.JSONObject;

public class WhoAPIExample {
    public static void main(String[] args) {
        try {
            String urlString = "http://api.whoapi.com/?domain=whoapi.com&r=domainage&apikey=demokey";
            URL url = new URL(urlString);

            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");

            BufferedReader reader = new BufferedReader(
                new InputStreamReader(conn.getInputStream())
            );

            StringBuilder response = new StringBuilder();
            String line;

            while ((line = reader.readLine()) != null) {
                response.append(line);
            }

            reader.close();

            JSONObject data = new JSONObject(response.toString());

            if (data.getInt("status") == 0) {
                System.out.println("Domain: " + data.getString("domain_name"));
                System.out.println("Created: " + data.getString("date_created"));
                System.out.println("Expires: " + data.getString("date_expires"));
                System.out.println("Age (days): " + data.getInt("age_in_days"));
                System.out.println("Age (years): " + data.getDouble("age_in_years"));
                System.out.println("Requests remaining: " + data.getInt("_requests_available"));
            } else {
                System.out.println("API Error: " + data.getString("status_desc"));
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
