Tool changes
preview_b2b_leadsremoved
Preview verified B2B decision-maker lead datasets (65 YC/HN Tech Founders or 764 US Dental Clinics with live MX & SMTP verification) and get instant Base USDC x402 or Stripe download links.
Check an email address in real time (RFC 5322 syntax, live DNS MX lookup, typo suggestion, disposable and role-account flags). Checks the domain, not the individual mailbox. Supports VerifyPulse API key or HTTP 402 (x402) Base USDC micropayment.
after · 41% of words in common
Check an email address: syntax, whether its domain accepts mail, typo suggestion, disposable and shared-mailbox flags. Checks the domain, not the individual inbox. Costs $0.01 USDC on Base per call over x402, or one credit with an API key.
flatten_spfadded
Free. Replace the includes in a domain's SPF record with the IP ranges they resolve to, and return the TXT records to publish. Use it when an SPF record is at or over the 10-lookup limit.
monitor_sending_domainsadded
Free for up to 3 domains per call. Report what changed in SPF, DKIM, DMARC and MX since a previous run. Pass the `snapshots` object returned by the previous call as `previous`; the server stores nothing. The first call returns a baseline with no changes.
audit_sending_domainsadded
Free for up to 3 domains per call. Audit several sending domains at once and get a grade, SPF lookup count, DMARC policy, DKIM status and fixes for each, plus a snapshot to pass to monitor_sending_domains later.
Run a free real-time RFC 7208 SPF 10-DNS-lookup audit, DMARC policy (_dmarc) alignment check, and MX server inspection on any domain.
after · 25% of words in common
Free. Audit one sending domain: MX hosts, SPF with every include expanded and the true DNS lookup count against the limit of 10, DMARC policy including inheritance from the parent domain, and published DKIM keys. Returns a grade and the fixes to make.
verify_emailchangeddescription
before
Verify an email address in real time (RFC 5322 syntax, live DNS MX lookup, disposable domain filter, and zero-send SMTP handshake). Supports VerifyPulse API key or HTTP 402 (x402) Base USDC micropayment.
