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 details (registrar, registrant, expiry), full DNS record set (A, MX, NS, TXT, CNAME, etc.), email policy records (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains. Returned as a JSON object in response to the x402-paid POST request.
Example use cases
Audit email security configuration
“Check the mail policy for acmecorp.com — I want to know if they have SPF, DKIM, and DMARC set up correctly, and what their DNS records look like.”
Investigate suspicious domain infrastructure
“I got a phishing email that appears to come from paypa1-secure.com — can you pull the full domain intel on it including WHOIS ownership, DNS, TLS cert, and any subdomains?”
Monitor DNS changes against baseline
“Last week I recorded the DNS records for competitor.io — here's that baseline snapshot. Can you check if anything has changed since then?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-digitalocean?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 policy, TLS, and subdomains — without signing up for an API key. Ideal for agents that need pay-as-you-go domain lookups billed in USDC via x402, especially for security investigations, competitor research, or DNS change monitoring against a known baseline. Prefer alternatives if you only need a single signal (e.g. a dedicated WHOIS-only or DNS-only service) or if you require bulk/batch domain lookups at scale.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) may return empty or partial results
- WHOIS data may be redacted for privacy-protected domains
- TLS certificate data unavailable if domain has no HTTPS endpoint
- Baseline comparison fails if baseline object schema is malformed
- Payment failure or insufficient USDC balance blocks the request via x402 402 response
- Rate or quota limits may apply per wallet address
