One-call email verification for lead qualification and list hygiene: RFC 5322 syntax check, then a live MX lookup over DNS-over-HTTPS (Cloudflare, Google fallback). Detects non-existent domains (NXDOMAIN), null-MX domains that refuse mail (RFC 7505), and returns prioritized MX hosts. Query: ?email=someone@example.com. Verdict: deliverable | risky | undeliverable. 1h cache per address.
