eBay developers may not use its content or its data to train Artificial Intelligence (AI), nor may developers ingest eBay data into gen-AI models or tools. On June 24th, eBay updated its API license agreement where it added the new provisions and other terms.
eBay announced the new license agreement, writing the following:
“An updated API License Agreement was posted to our portal on June 24, 2025. We have made significant enhancements to our API License Agreement, including detailed data protection measures and compliance with international regulations. Important restrictions have been applied to the use of Restricted APIs and AI content. All developers are expected to be in full compliance with the API License Agreement, so be sure to take some time to read the updated document.”
Included in the updated agreement is a new definition: “”Restricted APIs” refers to any APIs provided by eBay that offer data or insights related to market trends, pricing strategies, sales volumes, user behavior, or related information whose access is specially granted to select Developers.”
eBay prohibits those select developers from ingesting Restricted API data “into any generative artificial intelligence model or tool (“AI”) licensed from or otherwise made available by a third party without eBay’s prior written consent, which may be granted or withheld in eBay’s sole discretion.”
eBay also included a warning to developers on how they use pricing tools that incorporate eBay data, requiring them to ensure the “eBay Enhanced Tools” comply with applicable law, “including without limitation complying with the FTC regulatory requirements on deceptive pricing.”
eBay also gave itself the right to develop tools that are competitive with eBay Enhanced Tools “provided that the technology does not incorporate and is not derived from or based on any of Developer’s Confidential Information” (excerpt).
