Domain Age Checker in PHP

Returns the registration date and the age in years and days.

<?php

use IpApiIo\Client;

$client = new Client(apiKey: getenv('IP_API_IO_KEY'));

$age = $client->domainAge('example.com');

var_dump($age['is_valid']);          // true
echo $age['registration_date'];      // "1995-08-14"
echo $age['age_in_years'];           // 30
echo $age['age_in_days'];            // 11000+

if (($age['age_in_days'] ?? PHP_INT_MAX) < 30) {
    // treat brand-new domains as higher risk
}

Check a list of domains in one request (throws if empty).

$batch = $client->domainAgeBatch([
    'example.com',
    'brand-new-domain.xyz',
]);

foreach ($batch['results'] as $domain => $age) {
    echo $domain, ' ', $age['age_in_days'];
}
