Reads live MX, NS, SPF, DKIM and DMARC; detects Google Workspace, Microsoft 365, Zoho, Proton, Fastmail, GoDaddy and Cloudflare Email Routing; merges SPF within the 10-lookup limit, keeps existing senders, and stages DMARC none -> quarantine -> reject. Domains that send no mail get a lock-down set. Use it when mail lands in spam, before a DMARC rollout, or for a client. DKIM keys are generated by the mail provider, so for those it gives the exact console path. Read-only; nothing is stored. Costs $1 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input, an unknown domain or a DNS failure returns an error and is not charged.
check_email_addresschangeddescription, annotationsmeaning changedCheck one email address without sending mail: syntax, whether the domain accepts mail (MX, null MX, implicit A), disposable-domain flag (CC0 list), role-account flag (info@, support@...) and free-provider flag. Verdict ok / risky / undeliverable. No SMTP probe, so mailbox existence is not confirmed.
Check one email address before you send to it: syntax, whether the domain accepts mail (MX, null MX or implicit A record), a disposable-domain flag (public CC0 list of about 9,900 domains), a role-account flag (info@, support@, noreply@...) and a free-provider flag. Returns a verdict of ok, risky or undeliverable with plain reasons. Use validate_email first if you only need syntax. No SMTP probe is made and no mail is sent, so it cannot confirm the mailbox exists. The address is not stored or logged. Read-only; one live DNS lookup via Cloudflare DoH. Costs $0.005 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or a DNS failure returns an error and is not charged.

Free. Return the price of check_email_address (and of the HTTP-only email test report), the payment network (Base) and the receiving address. No input, no network request, no payment.

Free. Check the syntax of an email address offline and get the normalized address and domain, before paying for check_email_address. No DNS lookup, no network request, no payment.
