How this service works
Live crypto trading intelligence for AI agents — real-time BTC signals, CVD, order flow, and active strategy setups, no API keys or signup. 43 pay-per-call endpoints total: trading data, AI inference (MiniMax M2.7 (456B-parameter Mixture-of-Experts)), web utilities, verification, and ERC-8183 ACP escrow with on-chain ERC-8004 reputation attestation (Agent ID 59646). Four payment rails: USDC on Base mainnet (default), USDC on Solana mainnet, HBAR/USDC on Hedera testnet, USDT on BNB Chain testnet. One free trial call per endpoint. Prices from $0.001/call.
Output
A JSON object containing the domain's creation date, expiration date, registrar name, and list of nameservers, e.g. {domain, created, expires, registrar, nameservers[]}
Example use cases
Verify vendor domain legitimacy before contract
“Before we sign with this new supplier, can you pull up their domain registration info? I want to see when domains-supply.io was created and who registered it so we know they're not a sketchy startup.”
Monitor expiring customer domains for renewal
“We're building a customer health dashboard. Can you check the expiration dates on these three customer domains so we can proactively alert them before they lose their registrations?”
Detect domain age for fraud assessment
“This client claims to be an established business but I'm suspicious. Can you look up their WHOIS data and tell me exactly when their domain was first registered? That'll help us assess how real they actually are.”
Technical details
Endpoint
GEThttps://agents.ai-rook.com/api/whoisWhen to prefer
Use this endpoint when an agent needs to retrieve domain registration metadata (registrar, dates, nameservers) without an API key or signup, paying only $0.005 USDC per call via x402 on Base mainnet. Prefer this over free WHOIS APIs when operating in a crypto-native, pay-per-call agent commerce context or when you need programmatic access without rate-limit concerns tied to authentication.
Side effects
- Domain not found or unregistered — likely returns empty or error response
- Invalid domain format — malformed input may return 4xx error
- WHOIS data unavailable for certain TLDs or privacy-protected domains
- Rate limiting or payment failure on x402 — 402 Payment Required if USDC payment not provided
- Stale or cached WHOIS data may not reflect very recent registration changes
