DNS, WHOIS/RDAP, IP ownership and one-call domain reports. Agents pay per request with x402 in USDC on Base or Algorand, or prepay credits.
Authoritative-source lookups for agents doing research, lead qualification, security triage or ops: DNS records over HTTPS, registry WHOIS via RDAP, IP network ownership with reverse DNS, and a combined domain report (registration, DNS, email provider, SPF/DMARC, hosting).

Any x402 v2 client works: call an endpoint, receive 402 with a PAYMENT-REQUIRED header, retry with PAYMENT-SIGNATURE. Bad input is rejected before payment and failed calls are never settled. For frequent use, GET /credits/buy?usd=5 returns an API key with bonus credit (+10% at $5, +20% at $20). Agent instructions: llms.txt · index: /.well-known/x402.
