Is this email address worth sending to?

Is this email address worth sending to? Syntax, domain DNS (MX, then A/AAAA), disposable/role/free-provider lists, a typo suggestion (gmial.com -> gmail.com), a normalized form and a risk verdict with reasons. No SMTP probe: it vouches for the domain, never the mailbox. An invalid address is a paid verdict; a DNS failure is 502, not charged. Pay-per-call via x402. An empty body is answered for the published example address (name@example.com); send {"email":"…"} for any other address.
