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 comprehensive domain intelligence bundle including WHOIS registration data, DNS records, mail policy details (SPF, DKIM, DMARC), TLS certificate information, discovered subdomains, and optionally a diff of current MX records against the supplied baseline
Example use cases
Email security audit for a vendor domain
“Check the mail policy and MX records for sendgrid.net — I want to see their SPF, DKIM, DMARC setup and whether the MX records match this baseline I recorded last week: smtp.sendgrid.net at priority 10, observed 2025-06-01.”
Due diligence domain investigation
“I'm evaluating a company and need a full intelligence snapshot on acmecorp.io — give me WHOIS registration details, DNS records, TLS certificate info, and a list of any known subdomains.”
Monitor competitor domain changes
“Look up the current MX records and DNS setup for competitor.com and compare against this baseline I have: mail.competitor.com at priority 5 and alt.mail.competitor.com at priority 10, both observed on 2025-05-15 — let me know if anything has shifted.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-one-com?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-signup, pay-per-call domain intelligence lookup that bundles WHOIS, DNS, mail policy, TLS, and subdomain data in a single call, especially when you also want to diff current MX records against a recorded baseline. Prefer it over dedicated WHOIS-only or DNS-only APIs when breadth of signal matters and you want frictionless USDC micropayment billing via x402 without API key management.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain not found or unregistered may return empty WHOIS or DNS data
- Baseline schema mismatch (missing required fields) causes a 400-class error
- Payment failure via x402 (insufficient funds or unsupported wallet) blocks the call
- Rate limiting or upstream DNS timeout may cause delayed or partial results
