GET /v1/email-validate
unprobed
Email validation and email list cleaning. Checks each email address for RFC syntax, a live MX record lookup returning the real mail hosts, disposable-domain detection, role-account flags (info@, sales@, noreply@), and a free-provider flag, rolled into a per-address ok/risky/invalid verdict with reasons. Batch up to 25 email addresses per call. Domain-level DNS only, no SMTP mailbox probe. Keyless.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
