Amazon's Muse block exposes hurdles for agentic payments

Amazon's decision to block Meta's Muse shopping agent highlights a challenge for agentic commerce: an assistant's ability to make a payment does not guarantee permission to enter a merchant's website and complete a purchase.

Amazon said it cut off Muse after unsuccessfully asking Meta to exclude its marketplace from the service. According to GeekWire's September reporting, Amazon said Muse accessed its store without prior agreement, failed to identify itself and raised concerns about customer credentials and account access.

Amazon said third-party purchasing applications should "operate openly and respect service provider decisions about whether or not to participate," GeekWire reported.

Meta's published description presents a different security picture. It says Muse stores credentials securely without exposing passwords or payment details to the agent, requests approval before purchases and provides an audit trail. Its checkout options include Link, whose agent wallet generates one-time-use cards that conceal customers' actual card details, Meta noted.

Retailers choose different paths

The dispute does not establish that agentic shopping is being rejected across retail. Walmart announced Oct. 21 that it is introducing Agent Profiles, an Agent Gateway and terms governing AI agents shopping with Walmart and Sam's Club.

Profiles, scheduled to launch within a month, will distinguish agent purchases within customer accounts. Customers will be able to authorize agents, set spending limits and delete profiles. Walmart said its gateway will give agents a direct connection rather than requiring them to navigate pages designed for people, beginning with a beta for companies and developers.

Those differing approaches illustrate an emerging distinction for merchant services providers: accepting an agent's payment credentials and allowing the agent to shop are separate decisions.

Payment providers build trust mechanisms

Visa's Trusted Agent Protocol addresses part of that challenge. Introduced in October 2025 with Cloudflare, it uses cryptographic signatures to help merchants recognize approved agents and distinguish them from malicious bots. Its specifications support agent intent, consumer recognition and payment information.

Visa identifies mistaken bot blocking, support for guest and logged-in checkout, and visibility into the customer behind an agent as merchant concerns. Its developer documentation describes how merchant systems validate signed requests from approved agents.

These mechanisms address identification and transaction handling; participation remains a separate merchant decision. Amazon's restrictions and Walmart's planned gateway show that agentic commerce is developing through differing access policies, even as payment providers build common ways to recognize automated buyers.
