Amazon blocks Meta’s Muse AI agent from accessing Amazon.com

Amazon has blocked Meta’s Muse AI agent from accessing Amazon.com, according to a report by TechCrunch. Users attempting to purchase goods on Amazon via Muse received an error message stating that "continued access by an unauthorized AI agent violates Amazon’s Conditions of Use," effectively preventing further transactions through the agent.

The block was first observed on the evening of September 21, 2026, and was noted by GeekWire. Meta has not publicly responded to the restriction, and the company’s spokesperson did not provide a statement to TechCrunch.

Amazon’s decision to block Muse appears to stem from both competitive and operational considerations. The company has its own cohort of foundation models and operates one of the most popular inference platforms online, giving it little incentive to facilitate access for a rival AI agent. Additionally, Amazon may be wary of assuming liability for orders initiated by AI agents, particularly given the risk of errors or hallucinations in agent outputs. Muse is noted for having one of the lower hallucination rates among AI models, but even minimal errors could lead to customer disputes and vendor conflicts that Amazon would ultimately need to resolve.

The restriction underscores the growing friction between major platforms as AI agents become more embedded in consumer and commercial activities. It also raises questions about the future of interoperability between AI systems and e-commerce platforms, especially as companies race to integrate agentic capabilities into their services.
