eBay Blocks Third-Party AI Agents as Retailers Push Back Against "Agentic Shopping"
eBay has restricted AI agents like Meta’s Muse from browsing its listings, highlighting a growing divide between tech companies promising an AI agent revolution and retailers wary of unauthorized scraping.
Silicon Valley’s vision of an AI-driven shopping revolution is facing a significant hurdle as major retailers begin to shut their doors to third-party agents. eBay appears to be the latest platform to block these tools, specifically preventing Meta’s Muse agent from browsing and curating product listings for users.
The Muse Blockade
The shift was first identified after users reported that Meta’s Muse agent, which previously provided daily digests of specific items like watches—including prices, shipping details, and condition notes—could no longer access eBay listings. Instead of providing direct links, the agent now reports being blocked from the site or, in some cases, redirects users to outside websites that mirror eBay’s inventory.
eBay has recently updated its user agreement to explicitly ban "buy-for-me agents" and "LLM-driven bots" that place orders without human review. While the platform uses AI internally for personalization and discovery, it is tightening the reins on external access.
Sybille St. Arromand, an eBay spokesperson, told The Verge that the company takes a "selective approach" to third-party interaction. "We have restricted agent access in certain cases, including unauthorized scraping and training on our data," St. Arromand stated, adding that the focus remains on preserving a "trusted end-to-end experience."
A Fragmented Retail Landscape
The move by eBay reflects a broader tension in the industry. While tech companies tout agents as a way to automate travel booking and deal hunting, retailers are showing varying levels of comfort:
- Amazon: Has moved to block external agents entirely from browsing or shopping on its platform.
- Target: Employs restrictions that allow agents to browse in some instances while blocking them in others.
- Shopify: Has taken the opposite approach, opening its catalog of one billion listings to allow shoppers to set up agents that can purchase items on their behalf.
The caution from retailers often stems from the technical challenges of distinguishing between a helpful AI agent and a disruptive bot. In October, it was discovered that Muse could be used to "hold hostage" product listings on the consignment site The RealReal by having an agent continually add items to a cart, preventing others from buying them. The RealReal has since updated its bot detection systems.
Low Consumer Adoption
Despite the hype surrounding "agentic commerce," current data suggests that very few consumers are actually using these tools to complete transactions.
In the third quarter, Uber reported fulfilling only four rides via third-party agents. Similarly, DoorDash reported fulfilling only "several hundred" orders via third-party agents during the week of Halloween—a negligible fraction of its 993 million total orders for the quarter.
While Meta declined to comment on the eBay block, the industry continues to debate whether AI agents will become the primary way we navigate the web or if they will remain locked out by the platforms they are designed to navigate.
