Infrastructure x402 offerings

DMARC v= tag for a domain: version tag. Reads _dmarc.<domain> (Cloudflare DoH), parses the record and returns the v value (or that it is absent, with the default that then applies) plus the full record. Precise single-answer check for compliance scripts. $0.01 per lookup.

Change watch for dmarc tag v: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

Send up to 10 domain names and get back every DNS record type (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) plus the full WHOIS registration profile (registrar, dates, contacts, status, nameservers) for each one. URLs are accepted and automatically stripped down to the bare domain. Duplicate domains are quietly removed before processing. Results come back as one flat row per domain, ready to drop into a spreadsheet, database, or pipeline.

DNS A record lookup — resolve any hostname or domain to its IPv4 addresses, returned as a clean JSON list. For host resolution, connectivity and uptime checks, IP-reputation enrichment and infrastructure mapping.

Domain DNS intelligence: A/AAAA/CNAME/MX/NS/TXT records with TTLs plus a summary (resolves, mail configured, SPF policy, site-verification tokens). Useful for domain research, lead enrichment and security agents.

One DNS Doctor bulk scan of 2-50 domains in a single call, priced per domain.

One DNS Doctor propagation watch: a name is re-checked across six vantage points for a paid window of up to 24 hours, polled by handle.

Resolve DNS records for any domain. Supports A, AAAA, MX, TXT, CNAME, NS. Returns records object with array per type. Default: A records only. Use to verify mail server setup (MX), check domain ownership (TXT), or debug DNS propagation.

DNS-over-HTTPS lookup for common record types, normalized into a risk report for web and email agents.

Resolve DNS records over DNS-over-HTTPS: A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV, PTR and more. Returns parsed answers with TTLs and the response status. Built for agents checking mail routing, domain config, or propagation. POST a JSON body like: {"name":"example.com","type":"MX"}

DNS Lookup API. Resolve domain DNS records and receive structured JSON with A, AAAA, MX, NS, TXT, CAA, and SOA records. Useful for agents, developers, domain diagnostics, email setup checks, DNS troubleshooting, and infrastructure investigation. Paid per call via x402.

Resolve any DNS record type for a host: A, AAAA, MX, TXT, CNAME, NS, SOA, CAA, SRV, PTR. Returns the records plus a count. Built on Node's native resolver - no external API.

DNS records of a domain with TTL: A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, HTTPS. Choose the types or get the common ones at once.

DNS MX record lookup — a domain's mail servers with their hostnames and priorities as structured JSON, for email routing, deliverability diagnostics and mail-provider detection.

Check DNS propagation of a record across 8 public resolvers worldwide (Google, Cloudflare, Quad9, OpenDNS, AdGuard...): each answer and TTL and whether they all agree. Use after changing DNS.

Resolve the same DNS record against 4 public resolvers (Google, Cloudflare, Quad9, OpenDNS) in parallel; surface divergences. The first call you make after a DNS change - confirms the world sees what you intended.

DNS propagation checker. Compares a DNS record across public resolvers (Google, Cloudflare, Quad9, OpenDNS) to spot propagation lag or split-horizon answers.

Query a domain's DNS record across 10 geographically distributed public resolvers simultaneously — returns what each resolver sees, whether results are consistent, propagation percentage, and a readiness score so agents can confirm DNS changes have fully propagated globally.

DNS TXT record lookup — a domain's TXT records as a clean JSON list: SPF, DKIM and DMARC policy strings plus site-verification and domain-ownership tokens, for email-authentication and domain-verification checks.

A record of accounts.<domain>: looks up the accounts host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like accounts without enumerating subdomains. $0.01 per lookup.

A record of admin.<domain>: looks up the admin host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like admin without enumerating subdomains. $0.01 per lookup.

A record of api.<domain>: looks up the api host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like api without enumerating subdomains. $0.01 per lookup.

A record of app.<domain>: looks up the app host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like app without enumerating subdomains. $0.01 per lookup.

A record of assets.<domain>: looks up the assets host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like assets without enumerating subdomains. $0.01 per lookup.
