x402 Email Validate

Email address validation and deliverability scoring. Checks syntax, normalizes the address (including IDN and punycode), resolves live MX records and identifies the mailbox provider, and flags disposable throwaway domains, role accounts (info@, sales@) and free providers. Suggests a correction for likely typo domains and returns a 0 to 1 confidence score plus a deliverable / risky / invalid verdict. Use it to clean a signup form, scrub a lead list, or block junk registrations.
