How this service works
Domain in, WHOIS, DNS, mail policy, TLS certificate and subdomains out. Pay per call in USDC over x402. No signup, no API key.
Output
A structured report containing: WHOIS registration data (registrar, dates, registrant), DNS records (A, AAAA, MX, NS, TXT, CNAME), mail policy records (SPF, DKIM, DMARC), TLS certificate details (issuer, validity, SANs), and an enumerated list of discovered subdomains.
Example use cases
Email security audit for a vendor domain
“Check the mail policy for sendgrid.net — I need to see whether they have SPF, DKIM, and DMARC properly configured before we start sending email on their behalf.”
DNS change monitoring against baseline
“I recorded shopify.com's DNS records last week — can you re-query them now and compare against that baseline so I can see what changed?”
Subdomain enumeration for security review
“Run a full domain intel scan on acme-corp.io and list all the subdomains you find along with their DNS and TLS certificate details — I'm doing a pre-engagement recon.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-bunny-dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call domain intelligence snapshot — combining WHOIS, DNS, mail policy, TLS, and subdomains — without signing up for an account or managing an API key. Ideal for ad-hoc lookups, agent workflows that need pay-as-you-go pricing in USDC, or when you want to compare current DNS state against a previously captured baseline.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) may return empty or error response
- Payment failure via x402 prevents the call from being processed
- Rate limits or upstream DNS timeouts may cause partial or failed results
- Baseline object with mismatched domain field may cause comparison errors
