AI agents that shop, compare, buy and check out for people and businesses, the protocols they use, and how merchants get ready for them.
Cloudflare's paper lists 14 problems agents create for websites, and HUMAN found Meta's Muse made 72% of AI agent requests.
Our takeArkose Labs found 97.7% of legitimate agent sessions carried no verified identity, and Muse, which HUMAN found made 72% of agent requests, is adding shopping tools.
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.
Across 330 test runs buying TVs, laptops and hair tools, the best agents hit 82% while the five cheapest models averaged 50%.
Our takeVisa has its own stake in how agent shopping is framed, but the failure patterns still matter: agents often bought the wrong product or never asked about requirements like return windows and compatibility.
Andy Jassy wants Amazon's own assistant to be the main way people shop its store, though he hinted the block on outside agents may ease.
Our takeAlexa for Shopping looks set to be the agent that matters for brands' Amazon revenue, since Amazon intends to keep shoppers and sponsored placements inside it, though the 50% spending figure is likely correlation.
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.
