Resolve a domain's DNS records (A/AAAA/MX/NS/TXT/CNAME) and flag basic email/security posture

Domain registration facts over RDAP (structured WHOIS): registrar, creation and expiry dates, status codes, nameservers

Email and DNS Cutover Review — Reviews a pasted plan, script or configuration for a change to a domain's mail and DNS on Cloudflare (turning on Email Routing, moving MX records, forwarding rules, sending alert mail from a Worker with the send_email binding, SPF, DKIM and DMARC records, deleting the records of an old host, the subject and sender name of automatic mail) and lists the ways it fails without any error. It flags sends to addresses the binding cannot reach, recipient lists that stop a…

One-call email verification for lead qualification and list hygiene: RFC 5322 syntax check, then a live MX lookup over DNS-over-HTTPS (Cloudflare, Google fallback). Detects non-existent domains (NXDOMAIN), null-MX domains that refuse mail (RFC 7505), and returns prioritized MX hosts. Query: ?email=someone@example.com. Verdict: deliverable | risky | undeliverable. 1h cache per address.

End-to-end email-auth report for a domain: SPF + DMARC + DKIM (probes common selectors automatically) + MX records + score 0–100. The one call to make when 'why is our mail going to spam?' lands in your inbox.

Pay-per-call email syntax and public DNS/mail posture preflight. No mailbox-level SMTP claim.

Detect which email service a domain uses (Google Workspace, Microsoft 365, Zoho, Proton, OVH, IONOS...) from its MX and SPF records, plus corporate spam filters and other senders. For B2B sales and audits.

Email validation: syntax, domain MX records and disposable-domain flag. Sends no email; the address is not stored.

Validate email addresses: RFC-style syntax checks, IDN domain normalization, live MX lookups with A/AAAA fallback (DNS-over-HTTPS), disposable-domain detection, role-address detection (info@, support@), free-provider flagging, and typo suggestions for popular providers (gmial.com -> gmail.com). Single address or batches up to 50. POST a JSON body like: {"emails":["ada@example.com","bad@mailinator.com","typo@gmial.com"]}

Email verification and deliverability check without sending anything: syntax, MX records, disposable-domain detection (121k+ known domains), role-account and free-provider flags. JSON verdict with a bounce/deliverability risk level. Validate emails for signup fraud prevention, list hygiene and lead qualification. $0.004 USDC per call, pay via x402, no API key.

Takes one email address and tells you whether it can actually receive mail. Returns a verdict of valid, invalid, or risky, splits the address into username and domain, and flags free providers and role accounts like admin@ or support@. One address per call.

Does accounting@<domain> look deliverable?
