Frequently Asked Questions
RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. For .biz domains, RDAP provides structured JSON responses with registration data, nameservers, and availability status directly from the authoritative registry.
Use DomScan's API: curl "https://domscan.net/v1/status?name=example&tlds=biz" - This queries the official RDAP server and returns availability status in JSON format.
The official RDAP endpoint for .biz domains is https://rdap.neustar.biz/rdap. DomScan automatically routes queries to this endpoint for accurate results.
