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
A structured report containing WHOIS registration details (registrar, registrant, expiry dates), full DNS records (A, MX, NS, TXT, CNAME, etc.), mail authentication policy (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains for the queried domain.
Example use cases
Domain ownership and registration audit
“Can you look up who owns acmecorp.io and when it was registered? I also want to see the full DNS setup and whether their TLS certificate is still valid.”
Email deliverability and security check
“Check the mail policy records for newsletter.example.com — I need to know if they have SPF, DKIM, and DMARC configured properly before I trust emails coming from that domain.”
Baseline DNS change monitoring
“I recorded DNS records for competitor.com last week — here's the baseline snapshot. Can you fetch the current domain intel for competitor.com and compare against those records to see if anything changed?”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-domainfactory?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive, multi-faceted domain intelligence in a single call — covering WHOIS, DNS, mail policy, TLS, and subdomains simultaneously — without signing up for an account or managing API keys. Especially useful for agents that need pay-as-you-go access (at $0.009 per call) for sporadic domain lookups, competitive research, security audits, or DNS change detection workflows.
Side effects
- Domain not found or unregistered — returns empty or null WHOIS fields
- DNS resolution failure for the queried domain
- Payment not received or x402 transaction rejected — request not processed
- Invalid domain string exceeding 253 characters or malformed input
- Rate limiting or upstream WHOIS/DNS query throttling
- Baseline object provided with missing required fields (domain, observed_at, records)
