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 report including: WHOIS registry data (registrant, registrar, expiry), DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy analysis (SPF, DKIM, DMARC), TLS/SSL certificate details, and discovered subdomains.
Example use cases
Audit new vendor domain security
“Before we integrate with this vendor, can you run a full domain audit on acmecorp.io — I want their WHOIS owner info, DNS records, whether their SPF and DMARC are properly configured, and their TLS cert details?”
Detect DNS changes from baseline
“I recorded acmecorp.io's DNS records last week — here are the baseline records I saved. Can you check the domain again now and flag anything that has changed since then?”
Investigate suspicious domain
“I got a phishing email from someone claiming to be from payments-secure-bank.net — can you look up that domain's WHOIS, DNS, mail policy, and TLS certificate so I can figure out if it's legit or fake?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-one-com?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, comprehensive domain intelligence bundle (WHOIS + DNS + mail policy + TLS + subdomains) without signing up for an account or managing API keys. Ideal for ad-hoc domain audits, security investigations, or automated enrichment pipelines that pay per query in USDC. Prefer it over dedicated DNS resolvers when you need the full cross-section of domain metadata in one request.
Side effects
- Invalid or non-existent domain name — returns error with no records
- WHOIS data unavailable for certain TLDs — partial response without WHOIS
- Payment not completed via x402 — 402 Payment Required response before data is returned
- Rate limiting or temporary upstream DNS resolver failures
- Domain input exceeds 253 character limit — validation error
- TLS certificate unavailable for domains without HTTPS — partial response
