Kompy offers a robust Walmart product data API designed for developers and AI agents, providing comprehensive access to the entire Walmart catalog. This powerful API delivers live prices, current stock levels, seller information, customer reviews, and crucially, a full price history for every product, all presented as clean JSON.
The API is versatile, supporting both traditional RESTful endpoints and the Multi-Agent Communication Protocol (MCP) for seamless integration with AI agents like OpenClaw, Claude Code, and Cursor. This dual approach ensures that whether you're building a custom application in any programming language or empowering an AI agent with real-time e-commerce data, Kompy provides a consistent and reliable interface. Developers benefit from deterministic schemas, small payloads, and structured error responses, simplifying integration and ensuring data integrity.
One of Kompy's standout features is its unparalleled historical data. The platform meticulously records the Walmart marketplace around the clock, capturing hourly snapshots of price, stock, and buy-box changes for every tracked SKU. This means users gain access to the full Walmart price history, granularized per seller, extending back to the very first day of tracking. This extensive historical data is a unique offering, providing a significant advantage for market analysis, competitive intelligence, and identifying arbitrage opportunities, such as scanning clearance items for profitable flips on other platforms like Amazon.
Key API operations include kompy.product for full product records (price, stock, seller, rating), kompy.search for querying the live catalog with advanced sorting and filtering, kompy.history for per-seller price and stock history, and kompy.reviews for customer feedback. The API is designed for ease of use, requiring no specific SDK, and every response includes a request_id for traceability.
Kompy is compatible with a wide range of tools and frameworks, including LangChain, OpenAI Agents SDK, n8n, and any system that speaks plain HTTP or MCP. The service offers flexible pricing plans, from Hobby to Business, all starting with free credits, allowing users to begin making real requests immediately without commitment. This commitment to transparency and accessibility makes Kompy an essential tool for anyone needing deep, reliable, and historical Walmart product data.
