AI agents are shopping like never before—and tools like Mastercard’s ‘Pay for Machines’ could turbocharge the trend

AI agents are making waves in the world of shopping, with tools like Mastercard’s “Agent Pay” poised to accelerate the trend. According to Mastercard’s Head of Product, Jorn Lambert, the surge in popularity of mass-market personal agents has led to a rapid acceleration in agentic commerce. Previously, industry leaders believed that agent-to-agent communication protocols like MCP and ACP would be the key drivers, but this assumption has been proven wrong.

Instead, products like Meta’s Muse and OpenAI’s Dots have created a critical mass of consumers eager to have their agents do their shopping for them.

To cater to these consumers, Mastercard has introduced “Agent Pay,” a tool that simplifies transactions not only with retailers but also with government services, including parking tickets. Moreover, Mastercard recently unveiled a tool enabling small business users to launch ad campaigns. For instance, a granola bar company allowed its agent to spend $400 on a social media campaign, which encompassed everything from purchasing ads on TikTok and Instagram to acquiring creative elements like images, music, and a script—all accomplished in a matter of minutes.

A key aspect of Mastercard’s solution is its utilization of x402, a payments protocol initially conceived for the internet but only recently revived by Coinbase. This open-source protocol serves as a messaging language for various payment methods, such as credit cards, debit cards, or stablecoins. Its open-source nature allows anyone to utilize or build upon it.

Another significant feature of Agent Pay is its potential to facilitate micropayments, which involve paying minimal amounts like 27¢ or $1.87 for online content. In the past, digital merchants and financial networks have been hesitant to embrace such payments due to processing costs. However, with stablecoins and agents willing to negotiate prices for even small data pieces, we can anticipate a rise in à la carte micro-offerings, replacing the need for monthly subscriptions to access content.

While predicting the adoption of new technology is always uncertain, Mastercard’s Lambert believes that tools like Agent Pay will give rise to numerous innovative businesses founded by college students experimenting in their dorms. The author of this report, Jeff John Roberts, concludes that it’s an exciting time for agentic commerce and looks forward to seeing the diverse ways in which AI agents will reshape shopping and business models.
