Domain Research
Looks up WHOIS data and scans seven domain marketplaces (Sedo, Afternic, Atom, and others) to help you research domains for acquisition. Hits a free API at mcp.domaindetails.com that returns registrar info, creation dates, nameservers, and current listings with prices. Includes evaluation rubrics weighted by use case: brand domains get scored on memorability and length, SEO domains on backlinks and keyword match. The workflow pushes you to check Wayback Machine history before buying, which is smart since spam penalties stick around. Rate limit is 100 requests per minute with no auth required. If your domain is taken, it suggests the "get/try/use" prefix patterns that everyone uses now.
