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 structured domain intelligence report covering: WHOIS registration details (registrar, registrant, expiry), full DNS record set (A, MX, NS, TXT, CNAME, etc.), email authentication policies (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and discovered subdomains.
Example use cases
Vendor security due diligence
“Before we onboard this new vendor, can you check vendorcorp.io and pull their WHOIS ownership info, DNS setup, whether they have proper SPF and DMARC mail policies, and if their TLS certificate is valid and who issued it?”
Phishing domain investigation
“We got a suspicious email from support@secure-mybank-login.com — can you look up that domain and tell me who registered it, when, what DNS records it has, and whether it has any legit mail security policies set up?”
Monitoring competitor subdomain exposure
“I want to see what subdomains rival-startup.com is exposing publicly — can you run a full domain intel lookup and list all the subdomains you find along with their DNS records?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-nazwa-pl?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive, multi-faceted domain intelligence in a single call without API key registration — especially suitable for ad-hoc agent workflows, one-off security audits, or automation pipelines that require WHOIS, DNS, mail policy, TLS, and subdomain data together. Prefer this over separate specialized tools when cost-per-call economics fit your use case and you want frictionless USDC-based micropayments via x402.
Side effects
- Invalid or non-existent domain returns an error or empty result set
- WHOIS data may be redacted for privacy-protected registrations
- Subdomains list may be incomplete if DNS zone transfer is not permitted
- TLS certificate data unavailable if domain has no HTTPS endpoint
- Payment failure via x402 results in 402 response and no data returned
- Rate limiting or abuse detection may block repeated calls for the same domain
