All common DNS records for a domain in one call: A, AAAA, MX, TXT, NS, SOA, CNAME, CAA and HTTPS, plus DNSSEC validation state. A complete DNS snapshot for audits, migrations and change tracking. $0.01 per domain.

Reverse DNS (PTR) lookup: the hostname for an IPv4 or IPv6 address, with the arpa name and TTL. Identify servers, mail hosts and hosting providers from an IP. $0.01 per lookup.

DNSSEC check for a domain: whether DS and DNSKEY records exist, whether the resolver validates the chain (AD flag), signing algorithms used. Security posture and DNS hygiene audits. $0.01 per check.

DNS CAA record lookup: which certificate authorities are allowed to issue TLS certificates for a domain (issue, issuewild, iodef), parsed. Certificate policy audits and issuance troubleshooting. $0.01 per lookup.

Natural-language Q&A over the x402 Base settlements warehouse. POST {question}. Backed by 132M settlement rows on Cloudflare R2 + pre-aggregated daily_stats (388 days, May 2025 - Jun 2026), queried via Anthropic Sonnet + DuckDB. Returns {answer, sql_trace, model, upstream_ms}; sql_trace lets the caller verify the data path is real, not hallucinated. $0.05 USDC on Base.
