How to lookup domain WHOIS in PHP

Let’s make this super easy. We will start by adding our desired API to our library with the following reference:

"require": {
"cloudmersive/cloudmersive_validate_api_client": "^1.4",

Then call the function domainPost:

require_once(__DIR__ . '/vendor/autoload.php');
// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');
$apiInstance = new Swagger\Client\Api\DomainApi(

new GuzzleHttp\Client(),
$domain = "domain_example"; // string | Domain name to check, for example \"\". The input is a string so be sure to enclose it in double-quotes.
try {
$result = $apiInstance->domainPost($domain);
} catch (Exception $e) {
echo 'Exception when calling DomainApi->domainPost: ', $e->getMessage(), PHP_EOL;

Our output for today’s example,, looks like this:

"ValidDomain": true,
"WhoisServer": "",
