How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with WHOIS data for the queried domain, including registrant information, registrar details, nameservers, registration and expiry dates, and status flags. The response includes a status field ('ok') and a roi_proof object showing compression ratio.
Example use cases
Domain ownership verification
“I need to verify who owns stripe.com — can you run a WHOIS lookup and tell me the registrant name, organization, and registrar?”
Domain expiry monitoring
“Can you check the WHOIS record for mybusiness.com and tell me when the domain registration expires so I know if it's about to lapse?”
Competitive domain research
“Look up the WHOIS info for competitor.io and tell me when it was registered, what nameservers it uses, and who the registrar is.”

Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/whois-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs programmatic WHOIS data with micropayment-per-call pricing via x402/USDC on Base, without needing a subscription or API key. It is well-suited for agents that perform on-demand, pay-as-you-go domain lookups within A2A or MCP workflows.
Side effects
- Domain not found or unregistered — empty or null WHOIS data returned
- Invalid domain format — malformed input may return an error
- Rate limiting or payment failure — x402 payment required per call; failed payment results in 402 response
- WHOIS privacy protection enabled — registrant details may be redacted
- TLD not supported — some ccTLDs may not return full WHOIS data
