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 containing: WHOIS registry record (registrar, registrant, dates), DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy evaluation (SPF, DKIM, DMARC presence and validity), TLS certificate details (issuer, expiry, SANs), and a list of discovered subdomains.
Example use cases
Security audit of a vendor domain
“Run a full domain intel check on acmecorp.io — I need their WHOIS ownership info, DNS records, TLS cert details, and whether their mail policy is properly configured with SPF and DMARC.”
Detecting DNS changes over time
“I recorded the DNS records for example.com last week — here's my baseline snapshot. Can you check the current DNS state and tell me what's changed since then?”
Investigating a suspicious domain
“There's a domain, suspicious-login-portal.net, that showed up in our phishing logs. Can you pull the WHOIS, DNS records, TLS certificate, and any subdomains for it so I can understand who's behind it?”

Choose this endpoint when you need a comprehensive, multi-signal domain intelligence report in a single call — covering WHOIS, DNS, mail policy, TLS, and subdomains together — without registering an account or managing an API key. It is especially useful for agents that need on-demand, pay-per-use domain lookups (at $0.009 USDC per call via x402) for security audits, vendor due diligence, phishing investigations, or DNS change detection with baseline comparison.
Side effects
- Invalid or malformed domain name returns a 400-level error
- Domain does not exist (NXDOMAIN) may return empty or partial results
- WHOIS data may be redacted for privacy-protected registrations
- TLS certificate lookup fails if the domain has no HTTPS listener
- Rate or payment failure via x402 protocol returns 402 Payment Required
- Baseline comparison fails if baseline records are malformed or exceed 50 items
