## Documentation & README

# CatchDoms — Expired Domains API & MCP Server

CatchDoms exposes an **Expired Domains API** and an **MCP (Model Context Protocol) server** that aggregate expired domains from **16 auction platforms** (Dynadot, GoDaddy, DropCatch, SnapNames, Catched, Gname, BloomUp, UKBackorder, DomainLore, and 7 more) plus **100,000+ aged ccTLD domains** available at registration price. 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.

## Quick Start (Free — no API key needed)
