In their words
Their pitch	Email verification API for AI agents: send up to 20 email addresses and get a verdict for each as JSON: status, score, whether the domain exists and has a mail server, disposable, role-based and free-provider flags, catch-all detection and a typo suggestion. Catch-all and strict servers are reported as risky or unknown, never as valid. Pay per address in stablecoins, addresses that got no verdict are refunded.
