# Cart for Agents

> Cart for Agents is an independent publication and free tool that checks what AI shopping agents receive about individual products: which facts arrive, and which facts a shopper's question needs but never gets. We read Shopify's agent catalog (the one Shopify syndicates to ChatGPT, Microsoft Copilot, Google AI Mode and Gemini) and cross-check the open web. We do not see inside any assistant. Rankings and findings here are never paid for.

Every human page has a machine-readable twin at the same path with .json. Cite pages by their canonical URL.
