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 containing WHOIS registration data, DNS records (A, MX, NS, TXT, etc.), mail authentication policy (SPF, DKIM, DMARC), TLS/SSL certificate details, and enumerated subdomains for the queried domain. When a baseline is provided, the response can highlight changes since the last observation.
Example use cases
Security audit of a vendor domain
“I'm vetting a new vendor — can you pull the full domain intel on acmecorp.io? I want to see their WHOIS ownership, DNS setup, TLS certificate validity, mail policy, and any subdomains that are exposed.”
Detect DNS changes since last observation
“Check domain intel for example.com and compare it against this baseline I recorded last week: the NS records were ns1.example.com and ns2.example.com, observed on 2024-06-01T00:00:00Z. Flag any changes.”
Email deliverability investigation
“Can you look up the full domain intel for outbound.mycompany.com? I specifically need to see the SPF, DKIM, and DMARC mail policy records to debug why our emails are landing in spam.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-vercel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, all-in-one domain intelligence snapshot — WHOIS, DNS, mail policy, TLS, and subdomains — in a single call without signing up for an API key or managing credentials. It is ideal for ad-hoc investigations, security audits, or agent workflows that need to pay programmatically per lookup using USDC via x402. Prefer alternatives if you need continuous real-time monitoring, bulk domain scanning at scale, or deeper threat intelligence beyond infrastructure-level data.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist or is not resolvable returns empty or error response
- Payment failure via x402 prevents the call from completing
- Rate limiting or network timeouts on upstream DNS/WHOIS lookups may delay or fail the response
- Baseline object with missing required fields (domain, observed_at, records) returns a schema validation error
