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 response containing: WHOIS registration data (registrar, registrant, expiry dates), full DNS record set, mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and enumerated subdomains — all for the queried domain.
Example use cases
Pre-acquisition domain due diligence
“Before we finalize purchasing the domain startup.io, can you pull its full WHOIS registration info, DNS configuration, TLS certificate, mail policy, and subdomain list so I can assess its history and setup?”
Email deliverability audit
“Our emails from acme.com keep landing in spam — can you check the mail policy records (SPF, DKIM, DMARC) and DNS configuration for acme.com so I can see what's misconfigured?”
DNS change monitoring against baseline
“I recorded the DNS records for mycompany.com last week — can you check it again now and compare against my baseline snapshot to see if anything has changed?”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-netcup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need broad, multi-signal domain intelligence in a single API call without account registration or API key management. It is ideal for on-demand lookups where you need WHOIS, DNS, mail policy, TLS, and subdomains together rather than querying separate specialized services. The pay-per-call x402 micropayment model makes it well-suited for low-volume, ad-hoc agent workflows where subscription costs are not justified. Prefer this over manual DNS tools or multi-service orchestration when an agent needs a comprehensive domain profile in one step.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist or is not resolvable — WHOIS/DNS sections may return empty or error
- Payment failure via x402 (insufficient USDC balance or wallet not configured) blocks the call
- Baseline object schema mismatch causes request rejection
- Rate limiting or temporary DNS resolver unavailability may cause partial results
- Private/redacted WHOIS (GDPR-protected registrants) returns anonymized registrant data
