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, dates, contacts), all major DNS record types (A, AAAA, MX, NS, TXT, CAA, SOA), mail security policy records (SPF, DKIM, DMARC), TLS/SSL certificate details, and discovered subdomains. When a baseline is provided, changes since that snapshot are highlighted.
Example use cases
Email security audit for a domain
“Check the mail policy configuration for acme-corp.io — I need to know if they have valid SPF, DKIM, and DMARC records set up, and whether anything looks misconfigured.”
Competitive domain infrastructure recon
“Give me a full DNS and subdomain breakdown for shopify.com — nameservers, IP addresses, MX records, and any subdomains you can find.”
Detect DNS changes since last snapshot
“Compare the current DNS records for mybrand.com against this baseline I recorded last week: NS records were ns1.example.com and ns2.example.com as of 2024-06-01T00:00:00Z — flag anything that has changed.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-hetzner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain intelligence snapshot in a single call — covering WHOIS, all DNS record types, mail security policy, TLS certificate, and subdomains simultaneously. It is ideal for no-signup, pay-as-you-go workflows via x402 where provisioning API keys to multiple specialist services (WHOIS API, DNS resolver, certificate transparency logs) would be impractical. Prefer it for security audits, infrastructure recon, and DNS change detection use cases where breadth of output per call matters more than depth in any single category.
Side effects
- Invalid or malformed domain name returns validation error
- Domain not found or not resolvable returns empty or partial results
- WHOIS registry throttling may result in incomplete WHOIS data
- Payment failure over x402 results in 402 response before any data is returned
- Baseline schema mismatch (missing required fields) causes request rejection
- Some subdomains may be undiscoverable due to DNS wildcard or private configurations
- TLS certificate lookup may fail if domain has no HTTPS endpoint
