io.github.vanakenj45/x402-agent-api · Verify this server

Answers "Is this email address valid?", "Will mail to it bounce?" and "Is it a throwaway, a shared inbox or a typo?" before an agent sends mail or saves a lead. Checks, without sending mail: syntax, whether the domain accepts email (MX records, an A/AAAA record as implicit MX, or a null MX that refuses all mail), disposable/temporary providers (a maintained list of thousands of domains), free webmail (Gmail, Outlook, Yahoo, ...), role accounts (info@, support@, noreply@), likely misspellings of big providers with a corrected suggestion (gmial.com → gmail.com), and the domain's SPF and DMARC records and email provider. Returns a verdict (deliverable, risky, undeliverable), a 0-100 score and the reasons. The mailbox itself is not probed (no SMTP), so a catch-all domain accepts any name. An invalid address is still an answer (undeliverable); only a DNS failure is an error, not charged. You are only charged when a result is returned: invalid input (400) and upstream failures (4xx/5xx) are not settled. Costs $0.001 USDC per call via x402. Paid per call with x402 inside MCP (see the server instructions).
