Domain Registration Age & WHOIS Lookup (by Domain Name)

omnial/x402-domain-age-check

Given a domain name, returns its WHOIS registration creation date, age in days and years, registrar, and expiry date, plus a coarse risk indicator that flags recently-registered domains -- useful for screening a signup, sender, or link for fraud risk. A domain whose creation date can't be found in WHOIS data comes back with null age/registrar/expiry fields and a risk indicator of 'unknown', not an error.
