How this service works
Domain registration data from RDAP (the successor of WHOIS): registrar, creation, expiry and update dates, status codes, nameservers and DNSSEC.
Output
A JSON object containing: the domain name, registrar name and IANA ID, ISO 8601 creation/expiry/update timestamps, an array of domain status codes (e.g. clientTransferProhibited), an array of nameservers, a boolean DNSSEC flag, the RDAP source URL, and a human-readable plain-text summary string.
Example use cases
Verify domain ownership before outreach
“Before I contact the team behind openai.com, can you pull up the RDAP registration info for that domain — registrar, creation date, and status codes?”
Check domain expiry for renewal planning
“I need to know when myfavoriteproject.org expires and who the registrar is so I can plan the renewal in time.”
Audit DNSSEC and nameserver configuration
“Can you check the WHOIS details for acmecorp.net and tell me if DNSSEC is active and which nameservers are listed?”
Technical details
Endpoint
GEThttps://agent-toolbox.zafermemon87.workers.dev/v1/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, standards-compliant domain registration metadata (RDAP) including registrar, dates, status codes, nameservers, and DNSSEC — especially when a clean JSON response with a plain-text summary is needed. Prefer over raw WHOIS scraping when accuracy and machine-readable output matter.
Side effects
- Domain not found / unregistered — RDAP returns no record
- Invalid or malformed domain name input returns an error
- RDAP registry timeout or upstream unavailability
- TLD not supported by any known RDAP registry
- Rate limiting from upstream RDAP servers
