CatchDoms exposes an Expired Domains API and an MCP (Model Context Protocol) server that aggregate 22 sources: 21 auction and marketplace platforms (Dynadot, GoDaddy, DropCatch, SnapNames, Catched, Gname, Namecheap, NameSilo, Sedo, BloomUp, UKDroplists, DomainLore, Rakko, and more) plus an aged ccTLD database of 183,537 domains available at registration price. Authority+ adds a weekly pending-delete inventory of domains about to drop. Every domain is enriched with Trust Flow, Citation Flow, Domain Authority, backlinks count, referring domains, and Wayback history.
Use the REST API to integrate expired domain data into your tools, scripts, or pipelines. Use the MCP server to let Claude, Cursor, Windsurf, or any MCP-compatible AI assistant search expired domains conversationally — find drop-catches, check auction prices, and surface high-value aged domains programmatically.
