How this service works
DNS records, WHOIS, SSL certificate, subdomain discovery, and reverse-IP lookup with x402 payments.
Output
Returns a JSON object with parsed WHOIS fields including domain name, registrar name and URL, creation date, expiration date, last updated date, name servers array, DNSSEC status, domain status flags, registrant org, country, and emails. Note that field availability varies by TLD and some registrars redact personal data.
Example use cases
Domain expiry monitoring for assets
“Check the WHOIS record for mybrand.io and tell me when it expires and who the registrar is — I want to make sure we don't accidentally let it lapse.”
Threat intelligence domain vetting
“I need to investigate whether phishing-site.net is a recently registered throwaway domain — pull its WHOIS data so I can see the creation date, registrar, and any contact info.”
Competitive research on brand domain
“Look up the WHOIS info for competitor.com — I'm curious when they first registered it, what registrar they use, and whether DNSSEC is enabled.”
Technical details
Endpoint
POSThttps://dns.payapi.market/dns/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured domain registration metadata (registrar, dates, name servers, DNSSEC) for a specific domain. Prefer it over generic DNS record lookups when the goal is ownership, registration history, or expiry information rather than DNS resolution. It is ideal for security investigations, compliance checks, competitive research, and domain portfolio management.
Side effects
- Domain not found or not registered — may return empty/null fields
- TLD not supported by WHOIS parser — limited field availability
- Registrar data redacted under GDPR or privacy proxy — emails/org/country may be null
- Malformed domain input — lookup fails
- Rate limiting or payment failure — request rejected
