Kompy is a Walmart product data API and MCP server that provides live prices, stock, sellers, and full price history for the entire Walmart catalog as clean JSON.
What is Kompy?
Kompy is a REST API and MCP (Model Context Protocol) server that delivers real-time and historical product data from Walmart. It accepts product IDs or search queries and returns structured JSON with price, stock status, seller info, ratings, and reviews. The platform is built by Kompy (no parent company stated) and runs as a cloud service accessed via HTTP or MCP.
