How this service works
Pay-per-call market & on-chain data for Base trading agents over x402: live DeFi yields, cross-venue funding rates, token prices, Polymarket and RPC data — plus a pre-trade token-safety gate (GO/HOLD/BLOCK). No account, no API key; agents pay inline in USDC from $0.001/call.
Output
A JSON object containing the domain name, registrar name, creation date, expiry date, current status flags (e.g. client delete prohibited), and registrant information (may be null if redacted for privacy).
Example use cases
Domain expiry monitoring for portfolio
“Check the WHOIS record for mybrand.com — I want to know when it expires so I can make sure it gets renewed on time.”
Verify domain ownership before outreach
“Look up who owns and registered techstartup.io — I need the registrar and registrant details before I reach out about acquiring it.”
Fraud or phishing domain check
“Can you pull the WHOIS for this suspicious domain phishingsite.net and tell me when it was created and what its status flags are?”
Technical details
Endpoint
GEThttps://x402-data-api.sigrunner.workers.dev/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs WHOIS registration metadata for a domain — registrar, dates, status flags — without setting up an account or API key, paying only $0.01 USDC inline via x402. Prefer over traditional WHOIS APIs when operating in a crypto-native, accountless agent environment on Base.
Side effects
- Domain not found or unregistered — returns null or empty result
- Invalid domain format in query — may return error
- WHOIS privacy shielding — registrant field returns null
- Rate limits or upstream WHOIS provider timeouts
- TLD not supported by the underlying WHOIS service
