Tool changes

2026-10-17domain_checkchangeddescription
before
Live technical checks of a domain, measured by us at request time: A/AAAA, NS, MX records, SPF and DMARC policies, DNSSEC presence (DS), CAA, TLS certificate issuer, validity dates and hostname match on port 443, and HTTPS security headers (HSTS, CSP, X-Frame-Options). Returns a simple risk flag list. Use when an agent must sanity-check a company's or vendor's domain before trusting an email, link or supplier: does it resolve, receive mail, publish SPF/DMARC, and serve a valid TLS certificate. Paid per call via x402 (USDC on Base).

Sanity-check a vendor's or sender's domain before trusting an email, link or payment request. Measured at request time: A/AAAA, NS and MX records, SPF and DMARC policies, DNSSEC (DS), CAA, the TLS certificate on port 443 (issuer, validity, hostname match) and HTTPS security headers, with a list of risk flags. Technical signals only, not a reputation or ownership verdict. Use when an unfamiliar domain appears in an invoice, email or supplier record. $0.003 per call, USDC on Base (x402).
