Wildcard DNS check: resolves a random non-existent subdomain to see whether the zone answers everything (wildcard record), which affects subdomain enumeration, email catch-all behaviour and phishing risk. $0.01 per domain.
DNS change detection: snapshots a domain's A, AAAA, MX, NS, TXT and CA
DNS change detection: snapshots a domain's A, AAAA, MX, NS, TXT and CAA records, compares with the snapshot from your previous call (kept 90 days) and reports which record types changed. Call it on a schedule to get DNS hijack and misconfiguration alerts. $0.01 per check.
Tor exit node check: whether an IPv4 address is a current Tor exit, fr
Tor exit node check: whether an IPv4 address is a current Tor exit, from the Tor Project's published exit list (cached one hour). Fraud screening, abuse triage and access policy decisions. $0.01 per IP.
DMARC record parser and validator: paste any DMARC TXT string and get
DMARC record parser and validator: paste any DMARC TXT string and get the policy, subdomain policy, percentage, report addresses, alignment modes, whether it enforces, and warnings for common mistakes (p=none, missing rua, pct under 100, unknown tags). $0.01 per record.

Catch-all mailbox hint (no SMTP probing): estimates whether a domain a
Catch-all mailbox hint (no SMTP probing): estimates whether a domain accepts mail to any address, from provider defaults (Google Workspace/Microsoft 365 usually reject unknown users; many small hosts and Cloudflare Email Routing accept all), wildcard DNS and MX shape.
