WHOIS API and Bulk Domain Checking: Automation for Business

Manual WHOIS works for single lookups. For competitor monitoring, lead verification, or brand protection — automate with WHOIS API.

Python Example

pip install python-whois

import whois
w = whois.whois('example.com')
print(w.expiration_date)  # Expiration date
print(w.registrar)         # Registrar
print(w.name_servers)      # NS servers

PHP Example

$url = "https://www.whoisxmlapi.com/whoisserver/WhoisService"
     . "?apiKey=KEY&domainName=example.com&outputFormat=JSON";
$data = json_decode(file_get_contents($url), true);
echo $data['WhoisRecord']['expiresDate'];
