CompSniper documentation
Build with real eBay sold prices, AI-cleaned price summaries, batch workflows, and MCP tools.
CompSniper turns a product keyword into up to 240 completed eBay sales with sold price, date, condition, shipping, seller data, and a cleaned price summary. Use the REST API from your application or connect the hosted MCP server to an AI client.
