Meta’s Muse agent loses access to eBay, The Verge finds

eBay would not say whether it had added new limits. A spokesperson told The Verge it takes “a selective approach” to third parties. eBay has restricted agents in some cases, including unauthorised scraping and training on its data, the spokesperson said, and is talking to possible partners about outside agents that could bring in new shoppers.

The written rule came earlier. Unless eBay gives permission, its user agreement, in force since 20 February 2026, bars automated access by agents that buy on a user’s behalf, by bots run by large language models (the AI behind chatbots) and by any flow that places orders without human review, Value Added Resource reported. Agents could still browse the site until recently, The Verge says. Amazon blocks outside agents entirely, while Target lets some through.

Our Photoroom profile, built from 76 user sources read on 2 October, found that most of those reviewers are resale and marketplace sellers on Depop, eBay, Vinted and Shopify.

For those sellers, The Verge’s checks show Muse sending shoppers in some cases to outside sites that mirror eBay listings, so a listing can still surface in an agent’s results without the buyer landing on eBay.
