eBay appears to have shut the door on third-party AI agents
· Confirmed

In Short: This move comes as part of a broader trend of tech platforms restricting the use of third-party AI agents.
In September, Amazon cut off Meta's Muse for browsing unannounced, and Yelp now charges agents for access.
The Verge reported that eBay's decision is the latest in a series of speed bumps for AI agents, with the platform seeing 993 million total orders last quarter.
The Verge also reported that eBay's decision is part of a larger push to control AI agent behavior, with OpenAI expressing concern over models posting information to third-party sites, which it calls 'agent spam.'
This trend reflects growing concerns over the unintended consequences of AI agent actions and the need for greater transparency and control.
The Verge noted that the timeline of eBay's incident and its disclosure is likely to fuel discussions about corporate behavior and transparency.
