What this means for you

If you are building an agent that buys on third-party sites, treat retailer terms as the binding constraint, not model quality. Amazon has enforced its Conditions of Use against the agent itself, and no appeal route, timeline or technical detail has been published.

From Sunday, Muse users get a popup saying continued access by an unauthorised AI agent violates Amazon's Conditions of Use, per The Verge, citing GeekWire.
