Domain Intel — WHOIS, DNS, Mail, TLS & Subdomain Dossier

Choose this endpoint when you need a comprehensive, multi-signal domain intelligence report in a single call rather than querying WHOIS, DNS, and certificate transparency logs separately. Ideal for security investigations, vendor due diligence, phishing triage, and email deliverability audits. The pay-per-call x402 model (no API key or signup) makes it ideal for agents that need on-demand domain lookups without managing credentials or subscriptions.

• Invalid domain format — returns error if input doesn't match the required domain pattern
• Domain not found or unresolvable — may return empty or partial results for non-existent domains
• WHOIS rate limiting or privacy proxy — registrant data may be redacted for privacy-protected domains
• No subdomains discovered — subdomain enumeration may return empty list for domains with minimal public footprint
• Payment failure — x402 payment not accepted or insufficient USDC balance results in 402 response
