Resolve any domain in one call: A/AAAA, MX, NS, CNAME, SOA and TXT records, plus parsed email-auth posture — SPF policy, DMARC policy, and detected DKIM selectors. A drop-in nslookup/dig replacement for agents, resolved over DNS-over-HTTPS (DoH) with redundant resolvers and automatic failover. Keyless, pay-per-call, structured JSON.
