How this service works
Queries global registry metadata via the public RDAP protocol to find registration details.
Output
A JSON object containing the domain's registrar name, creation date (ISO 8601), expiration date (ISO 8601), a supported flag indicating whether WHOIS data is available for the TLD, a confidence level (e.g. 'high'), a data freshness timestamp (e.g. '2026-06'), and a disclaimer. Also includes a warnings array for any partial or uncertain data.
Example use cases
Domain expiry monitoring for portfolio
“Check the WHOIS record for mybrand.com — I want to know the registrar and the expiration date so I can tell if it's about to lapse.”
Verify domain ownership before outreach
“Look up who registered techstartup.io and when — I want to confirm the domain is legitimately registered before I reach out to them.”
Competitive research on rival site
“Can you do a WHOIS lookup on competitorsite.com and tell me when it was first registered and who the registrar is?”
Technical details
Endpoint
POSThttps://codepulse-api.hahavoid0.workers.dev/web/whoisWhen to prefer
Use this endpoint when you need structured WHOIS data (registrar, creation, expiration) for a specific domain without managing API keys or WHOIS parsing yourself. It is well-suited for agents that need quick, pay-per-use domain intelligence at $0.02 per call via x402 USDC on Base. Prefer this over raw WHOIS CLI tools when operating in an automated or agentic context that requires clean JSON output.
Side effects
- Domain not found or unsupported TLD — 'supported' field returns false
- Network timeout reaching WHOIS registry — HTTP error or empty result
- Invalid domain format in input — validation error returned
- Rate limiting by upstream WHOIS registry — degraded or missing data
- Stale data — 'data_as_of' may lag the real registry by weeks
