Four large platforms have taken different positions on letting outside AI agents reach their catalogs and checkout. This explains what each model means for discovery, payment data and product feeds.
Our takeAgent visibility on Amazon and Mercado Libre runs through their own listings and ads for now, while Walmart and Shopify reward product data that outside agents can read.
Amazon says millions more customers will get the option in the coming weeks, but has not said whether ads will appear in text replies.
Our takeFor brands on Amazon, a text reply fits very few products, and Workflow Labs research cited by PPC Land found Rufus narrowed 50 results to roughly five. Amazon has not said how products are picked in texts, whether sponsored prompts will run there, or whether Shop Direct merchants will see text-originated sales.
Agent Profiles let shoppers approve each order or set a limit, and an MCP-based Agent Gateway is in beta for developers.
Our takeWalmart gives outside agents their own identity and spending limits while keeping card data and purchase history in-house, so it can accept agent orders without becoming a simple fulfillment endpoint.
