How this service works
Pay-per-request data toolkit for AI agents — 13 no-auth tools, $0.005 USDC each via x402. Web search, read URL, crypto price/markets/trending, Wikipedia, news headlines, weather, FX rates, IP geolocation, DNS lookup, stock quotes, and domain WHOIS.
Output
Returns a JSON object with the queried domain name, its WHOIS status flags (e.g. 'client delete prohibited'), expiry date, last updated date, registrar name, original registration date, and a list of authoritative nameservers.
Example use cases
Verify domain ownership before partnership
“Before we sign this deal, can you look up the WHOIS record for acmecorp.io and tell me who actually owns it, when it was registered, and who the registrar is?”
Monitor domain expiry for a competitor
“Check when stripe.com's domain registration expires — I want to know if it's coming up for renewal soon.”
Investigate suspicious phishing domain
“I got a suspicious email from paypa1-secure.com — can you do a WHOIS lookup and tell me who registered it, when, and what nameservers it's pointing to?”
Technical details
Endpoint
POSThttps://x402deploy.vercel.app/api/domainWhen to prefer
Use this endpoint when you need quick, structured WHOIS data for a single domain without setting up API keys or subscriptions. The x402 micropayment model ($0.005 USDC) makes it ideal for occasional lookups in agent workflows. Prefer this over raw WHOIS CLI tools when you need clean, parsed JSON output. Not suited for bulk domain lookups or continuous monitoring at scale.
Side effects
- Domain not found or unregistered — may return empty or error response
- Invalid domain format input — returns validation error
- WHOIS rate limiting by upstream registry — may return incomplete data
- Very new domains may not yet appear in WHOIS databases
- Payment failure via x402 — request not processed if micropayment is rejected
