x402
Domain Intel — Pay-Per-Call Domain Intelligence (x402) is a paid API for AI agents from dns.halowerk.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-13).
Accepts a domain name and returns WHOIS, DNS records, mail policy (SPF/DKIM/DMARC), TLS certificate details, and subdomains — paid per call in USDC via x402.

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 for the queried domain containing: WHOIS registration data (registrar, expiry, owner), full DNS record set (A, MX, NS, TXT, CNAME, etc.), mail policy details (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and discovered subdomains. When a baseline is provided, results may indicate changes relative to the prior observed state.
Example use cases
Mail security audit for a domain
“Check the mail security setup for acme-corp.com — I need to see their SPF, DKIM, and DMARC records to find out if their email domain is properly protected against spoofing.”
TLS certificate and subdomain enumeration
“Look up the TLS certificate and enumerate all known subdomains for competitor-site.io — I want to understand their infrastructure footprint.”
Detecting DNS drift against a known baseline
“I have last week's DNS snapshot for mybusiness.com with records ['93.184.216.34','ns1.example.net'] observed on 2024-06-01 — run a domain intel check now and tell me if anything has changed.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-transip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain intelligence report in a single call — covering WHOIS, DNS, mail security, TLS, and subdomains simultaneously — without requiring API key registration. Ideal for pay-as-you-go scenarios, autonomous agents, and security/compliance workflows where per-domain cost ($0.009 USDC) is acceptable. Prefer over manual DNS tools or single-signal APIs when you need all domain signals aggregated. Use the baseline feature when monitoring for DNS drift over time.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) may result in empty or partial records
- WHOIS data may be redacted for privacy-protected registrations
- TLS certificate lookup fails if domain has no HTTPS service
- Payment not processed via x402 results in 402 response before data is returned
- Baseline domain mismatch (baseline.domain differs from domain field) may cause comparison errors
