Amazon has cut Meta’s Muse shopping agent off amazon.com after asking the company to opt the store out — and getting no deal. As of Sunday night, people trying to shop Amazon through Muse were seeing a popup: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.”
This is a platform-control fight, not a product recap. Amazon says Meta never notified it that Muse would access the store, the agent does not identify itself while browsing, and it appears to capture and store customer logins. That mix, Amazon argues, creates privacy and security risk. If a customer prompts Muse, the agent can also reach account pages and order history. Because Muse does not identify itself, Amazon says that is an undisclosed third party moving through customer accounts, processing transactions, and handling sensitive data without Amazon’s knowledge or consent.
“We think it’s fairly straightforward that third-party applications that offer to make purchases on behalf of customers from other businesses should operate openly and respect service provider decisions about whether or not to participate,” an Amazon spokesperson said. The company requested that Meta remove Amazon from Muse. Amazon said Sunday night it is in direct conversation with Meta and declined to comment on whether it would take legal action.
GeekWire reported Meta did not immediately comment. When Muse launched on Sept. 8, Meta said the agent “has no visibility into people’s passwords or payment methods,” and that credentials a user shares “go into secure storage, so Muse can use them without seeing them.”
An anti-bot wall, tested live
The Register asked Muse to find the best-reviewed ergonomic office chair, add it to a cart, and proceed to checkout. Muse reported: “Hit a snag: Amazon is showing an anti-bot wall that blocks automated browsers outright – the browser couldn't even get to the search page, so no chair was found or added. I didn't push past it, since the notice says continuing would violate Amazon's terms.”
The standoff is sharper because the companies already work together. Amazon products have been purchasable inside Facebook and Instagram since 2023, and Meta signed a multibillion-dollar deal in April to run agentic AI workloads on Amazon’s cloud. That partnership did not buy Muse a shopping lane on amazon.com.
Terms of use after the Perplexity ruling
Amazon has spent the past year trying to keep outside agents off its store, suing Perplexity over its Comet browser and moving to block shopping agents from Google and OpenAI. It won a preliminary injunction against Perplexity in March, then lost it on Aug. 4, when the Ninth Circuit ruled that under federal anti-hacking law the user — not the AI company — was accessing Amazon’s computers. The court denied rehearing on Sept. 10. That left Amazon a contract path: claims built on terms of service. The Muse message does not accuse anyone of hacking. It cites Conditions of Use.
Amazon’s own agents are the contrast. Alexa for Shopping researches products. Buy for Me shops other brands’ sites, and Amazon says that feature identifies itself and lets brands opt out. The company also has a commercial reason to keep the session on its pages: it generated more than $68 billion in ad revenue last year, a business that depends on people browsing Amazon and seeing sponsored products.
If a service has a public API, Muse can connect with credentials the user provides. If it has none, Meta says the agent can use the service through a browser the way a person would. Amazon is refusing that browser path, analogizing to food-delivery apps that need restaurant agreement and travel agencies that book with airlines. Agentic checkout, in that framing, depends on merchant consent as much as model skill.
If you ship shopping agents, treat self-identification, credential handling, and a real opt-out as product requirements — then watch whether Meta actually removes Amazon from Muse, and whether other retailers copy the Conditions of Use wall.
