eBay Blocks Meta's Shopping AI From Its Platform

It appears eBay has blocked AI agents, including Meta's Muse.

A reader told The Verge that over the past few weeks, he had Muse browse platforms including eBay every day to put together a list of watches for sale, complete with product links, prices, shipping fees and condition notes. This weekend, Muse could no longer retrieve any eBay links or details, and said it was blocked by the website.

The Verge reproduced the issue with other search queries, and found that in some cases Muse would redirect users to other sites instead.

What makes this interesting is that agentic shopping has been hyped for more than a year, with promises that AI will compare prices for you, track discounts for you, and even place orders for you. When it actually came to real-world rollout, the first barrier is not model capability, but e-commerce platforms.

For eBay, AI agents are an awkward proposition. They browse the site on users' behalf, but never view ads, never click sponsored listings, do not contribute to user session duration, and walk away with fully structured product data. The traffic ecosystem that the platform spends huge sums to build is bypassed entirely by an unseen automated program.

For users, agents like Muse do cut down a lot of hassle. Getting a curated daily watch list is far more comfortable than manually searching keywords and scrolling through dozens of pages of results. But this convenience only works on the premise that the platform is willing to allow scraping — and eBay clearly has not made up its mind to support that.

Meta has not made any public statement, and eBay has not given an official response either. As The Verge notes in its original report, after getting blocked, Muse will sometimes rephrase its requests and keep trying to access the data, like a person kicked out by security who circles back around to the side entrance.

After all the hype around AI agent shopping, the first party to take actual action is the e-commerce platform, not the tech side. This says more clearly than any demo ever could about who actually holds the keys to the gate.
