The easiest way is to use Clay’s built-in WHOIS enrichment to pull domain metadata like registration age, expiration, and security events. Just add your domain list to a Clay table and use the WHOIS enrichment action—no extra setup needed. For domain authority, Clay doesn’t directly provide that, but you can use external tools like Hunter.io for risk signals, or combine WHOIS data with other enrichments for a fuller picture. [1] [2] [3]
