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
Returns a comprehensive domain intelligence payload including: WHOIS registration data (registrar, registrant, expiry), all major DNS record types (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy records (SPF, DMARC, DKIM), TLS/SSL certificate details (issuer, expiry, SANs), and discovered subdomains. If a baseline is provided, the response may highlight differences from the baseline snapshot.
Example use cases
Email deliverability audit for a domain
“Can you check the mail policy for sendgrid.net — specifically SPF, DKIM, and DMARC — and let me know if anything looks misconfigured?”
Security audit of a competitor's domain
“Pull together everything you can on shopify.com: WHOIS ownership details, all DNS records, their TLS certificate info, and any subdomains that show up.”
Detecting DNS changes from a known baseline
“Here's a baseline snapshot of example.com's NS records from last week — can you check the current DNS state and flag anything that's changed?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-porkbun?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a single, consolidated domain intelligence report covering WHOIS, DNS, mail policy, TLS, and subdomains in one call without signing up for an API key or managing credentials — ideal for ad-hoc agent workflows, security audits, or one-off domain checks where pay-per-call economics ($0.009 USDC) make more sense than a subscription. Choose this over general DNS resolvers when you also need WHOIS, TLS, or email policy data in the same response.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) may return empty or partial results
- WHOIS data may be redacted (GDPR/privacy protection) for some registrars
- TLS lookup may fail if the domain has no HTTPS endpoint
- Rate or payment failure via x402 results in 402 Payment Required response
- Subdomains enumeration may be incomplete depending on zone transfer restrictions
