For weeks, one eBay shopper had a quiet routine: his Meta Muse agent scanned the marketplace each morning and assembled a daily digest of watches for sale, with links, prices, shipping, and condition notes. This weekend, the digest stopped coming. Muse told him it was blocked from the site. According to The Verge, which reproduced the failure with other searches, eBay appears to have shut third-party AI agents out of its marketplace — sometimes leaving Muse pointing users at sites that merely mirror eBay's listings.
eBay isn't confirming the move outright. Spokesperson Sybille St. Arromand declined to say directly whether new limits were imposed, but told The Verge that eBay takes "a selective approach" to third-party access and has "restricted agent access in certain cases, including unauthorized scraping and training on our data." She added that eBay is talking with potential partners about how agents could help new customers discover its inventory. Meta declined to comment.
The paperwork was already there. eBay's user agreement, in terms that took effect February 20, 2026, bars "buy-for-me agents" and "LLM-driven bots" that place orders without human review. What changed is the enforcement: until recently, agents like Muse could still browse listings even if they couldn't buy. Now the browsing itself appears off limits.
That puts eBay on a clear side of the split forming across retail. Amazon blocks external agents entirely; Shopify has gone the other way, opening its catalog of a billion listings so shoppers can set agents up to buy on their behalf; Target sits in between. Every marketplace is now deciding, one by one, whether the agent economy is a customer to serve or a bot to stop.
The caution isn't abstract. The Verge discovered in October that Muse could hold listings hostage on The RealReal by repeatedly adding a product to a cart; the consignment site tightened its bot defenses afterward. Retail sites were built assuming human shoppers with human limitations — not swarms of agents that never sleep.
Here's the awkward part: hardly anyone is actually shopping this way yet. Uber fulfilled only four rides via third-party agents in Q3 and around 500 Uber Eats orders during Halloween week; DoorDash reported only "several hundred" agent orders against 993 million total last quarter. The agentic shopping revolution is, for now, mostly a press release — and eBay just decided to negotiate its terms before the traffic arrives.
