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), DNS records (A, MX, NS, TXT, etc.), mail policy records (SPF, DKIM, DMARC), TLS certificate details (issuer, validity, SANs), and a list of discovered subdomains for the queried domain.
Example use cases
Investigate a suspicious sender domain
“Someone just emailed me from support@quickpay-secure.net — can you look up everything you can find on that domain? I want to see WHOIS, DNS, mail security policies, and TLS certificate details.”
Audit mail security for a competitor
“Can you check what mail security policies — SPF, DKIM, DMARC — mailchimp.com has set up, along with their DNS records?”
Map subdomains before a pen test
“I need a full domain intel report on acmecorp.io — especially any subdomains you can enumerate, plus DNS and TLS certificate info.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/registry-renewal-window?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call domain intelligence bundle — WHOIS, DNS, mail policy, TLS, and subdomains — without signing up for an account or managing API keys. It is ideal for ad-hoc, pay-as-you-go domain investigations, security research, or enrichment pipelines where you want to avoid subscription commitments. Prefer alternatives if you need real-time continuous monitoring or bulk batch lookups at high volume.
Side effects

- Payment failure via x402 returns 402 Payment Required
