Email Check

by APEX Email address verification in Email & messaging

x402 APIPassing, checked 3 h ago

Email verification: is one address deliverable, disposable or a role account? Check ONE email address before you send to it: pass [email protected] and get a verdict (deliverable-domain, role-account, disposable, bad-shape or no-mail-domain) from its shape, its MX records read live over DNS, 25 known disposable-mail domains and 27 role-account names like info, support and admin. The mailbox itself is not probed, and the answer says so. Paid in USDC on Base.
