How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object containing: DNS records (keyed by record type), WHOIS registrar information, an array of discovered subdomains, and a security headers object with a numeric score indicating how well the domain implements HTTP security headers.
Example use cases
Security audit of third-party vendor
“I need to assess the security posture of acmecorp.com before we onboard them — can you check their DNS records, security headers score, and any exposed subdomains?”
Investigating a suspicious phishing domain
“Someone flagged phishing-attempt-site.net as suspicious — can you pull the WHOIS registrar details and DNS records so I can see who owns it and how it's set up?”
Pre-launch domain health check
“We're about to launch on mybrand.com — can you do a full domain intel check including DNS records, subdomains, and security header scoring to make sure everything looks clean?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/domain-intel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a consolidated, single-call domain intelligence report covering DNS, WHOIS, subdomains, and security headers together — rather than calling separate specialized services for each. Ideal for security researchers, developers auditing third-party domains, or automated pipelines that need to quickly assess the legitimacy and security posture of a domain. Best when you want pay-per-call access with no account setup.
Side effects
- Domain does not exist or is unresolvable — returns empty DNS and WHOIS fields
- Rate limit or payment failure — HTTP 402 if USDC payment is not included or insufficient
- Invalid domain format in query parameter — may return error or empty result
- Private/reserved domains may return incomplete WHOIS data
- Newly registered domains may have incomplete propagation data
