How this service works
Web extraction, domain lookups and document tools for AI agents. Pay per call in USDC via x402 on Base or Algorand.
Output
Returns structured domain registration data sourced via RDAP, including the registrar name, registration creation date, expiration date, domain status flags (e.g. clientTransferProhibited), and a list of nameservers associated with the domain.
Example use cases
Domain expiry monitoring for portfolio
“Check when openai.com is set to expire and who the registrar is — I want to know if it's coming up for renewal soon.”
Verify domain ownership before outreach
“Before I reach out to this company, can you pull the WHOIS registration data for acmecorp.io so I can see who registered it and what its current status is?”
Due diligence on a domain acquisition
“I'm thinking about buying the domain vintagewatch.com — can you look up its registration history, creation date, expiry, and nameservers so I can assess it?”
Technical details
Endpoint
GEThttps://agentpay.agentpay-apis.workers.dev/lookup/v1/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need domain registration metadata — registrar, dates, status, nameservers — from the authoritative RDAP protocol. Prefer this over generic WHOIS scrapers when structured, machine-readable registration data is required. If you also need DNS records, IP ownership, or a combined domain report, consider the sibling DNS or one-call domain report endpoints on the same provider.
Side effects
- Domain not found or unregistered — returns empty or 404-equivalent response
- TLD not supported by RDAP — some ccTLDs may not have RDAP endpoints
- Rate limiting from upstream RDAP registries — may return timeout or error
- Invalid domain format passed as input — missing TLD or malformed string
- RDAP registry temporarily unavailable — upstream service outage
