# AgentBIT, pay as you go: Domain WHOIS API

> Full domain intelligence via RDAP (the registries' official WHOIS successor): registration and expiry dates with computed age, registrar, EPP status codes, nameservers, DNSSEC — plus derived risk flags (newly registered, hold status, expiring) and a clean availability answer for unregistered domains. Registry data, structured JSON, no scraping.
