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 registration details (registrar, registrant, expiry dates), full DNS records (A, MX, NS, TXT, etc.), mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains. If a baseline is provided, changes since the baseline observation can be highlighted.
Example use cases
Security audit of third-party vendor domain
“Run a full domain check on vendor-corp.com for me — I need to see their WHOIS info, DNS records, TLS certificate, mail policy, and any subdomains so I can assess their security posture before we sign the contract.”
Detecting DNS changes since last baseline
“Check acme.io's current DNS records and compare them against this baseline I captured last week: NS records were ns1.acme.io and ns2.acme.io, observed on 2024-06-01. Let me know if anything has changed.”
Email deliverability investigation
“Can you look up the mail policy for startup.io? I want to see their SPF, DKIM, and DMARC records to understand why our emails to them might be bouncing.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-all-inkl?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain intelligence report in a single call without managing API keys or subscriptions — ideal for one-off lookups, agent-driven security audits, or pay-as-you-go workflows. Prefer it over dedicated WHOIS or DNS tools when you need WHOIS, DNS, mail policy, TLS, and subdomains combined. The x402 micropayment model makes it suitable for low-volume, on-demand use cases where committing to a subscription is undesirable.
Side effects
- Domain not found or unresolvable — returns empty or partial results
- Invalid domain format (exceeds 253 characters or malformed) — request rejected
- WHOIS data unavailable for certain TLDs or privacy-protected registrations
- TLS certificate absent if domain has no HTTPS endpoint
- Payment failure over x402 — request not processed
- Rate limiting or temporary upstream DNS/WHOIS provider failures
