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 structured report for the queried domain containing: WHOIS registration data (registrar, registrant, dates), full DNS record set (A, MX, NS, CNAME, TXT, etc.), email authentication policy (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains.
Example use cases
Vendor domain security audit
“Check example-vendor.com for me — I need their WHOIS ownership info, DNS records, SPF/DKIM/DMARC mail policy, and TLS certificate details so I can assess them as a supplier.”
Subdomain enumeration for recon
“Enumerate all the subdomains and DNS records you can find for targetcompany.com — I'm doing a security assessment and need a full picture of their external footprint.”
Monitor domain configuration changes
“I want to compare the current DNS records for mybrand.com against this baseline I recorded last week — flag anything that's changed or been added.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-shopify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive, multi-signal domain intelligence in a single call — WHOIS, DNS, mail policy, TLS, and subdomains together — without signing up for an account or managing API keys. Ideal for agents that need on-demand domain recon at low cost ($0.009/call) and can pay programmatically via x402/USDC. Prefer this over standalone WHOIS or DNS tools when you want all signals in one response, or when you need to compare against a DNS baseline to detect changes.
Side effects
- Invalid or malformed domain name returns a 400 or validation error
- Domain does not exist or is unresolvable — partial results or empty record sets returned
- Payment failure via x402 — 402 response if USDC payment is not completed
- Rate limiting or abuse detection may block repeated calls for the same domain
- WHOIS privacy protection may redact registrant details
- TLS lookup may fail for domains without HTTPS
- Subdomain enumeration may be incomplete depending on DNS zone transfer policies
