How this service works
Domain registration data via RDAP (the structured WHOIS successor): registrar, creation/expiry dates, status, nameservers.
Output
Returns structured RDAP data for the queried domain, including registrar name, creation date, expiration date, current domain status flags, and nameserver hostnames.
Example use cases
Example prompt
“Can you look up the registration details for openai.com — I want to know the registrar, when it was created, when it expires, and what nameservers it uses?”
Technical details
Endpoint
POSThttps://agent402.tools/api/whoisWhen to prefer
Use this endpoint when you need structured, machine-readable domain registration metadata (registrar, dates, status, nameservers) via the modern RDAP protocol rather than parsing raw WHOIS text. Prefer over raw WHOIS scrapers when you need consistent JSON output across TLDs.
Side effects
- Domain not found or not registered — RDAP returns no data
- Invalid domain format provided — API may return validation error
- TLD not supported by RDAP — some legacy TLDs may lack RDAP coverage
- Network timeout or upstream RDAP registry unavailable
- Payment failure — x402 payment of $0.003 USDC not processed
