U.S.-listed cryptocurrency exchange Coinbase (COIN) is creating a new ecosystem that combines stablecoin-based micropayments with AI.
Building on the release earlier this year of x402, an open source payment protocol that enables instant stablecoin payments on any website, Coinbase engineers have added a discovery layer for AI agents, something like a “Google for agents,” that the firm is calling x402 Bazaar.
This matters because it’s about unlocking new paradigms within agentic commerce, a term often associated with humans setting out requirements and preferences for AI agents to shop for them.
In fact, the marketplace of things AI agents are going to want to buy is actually significantly bigger than the things that humans may want to buy, says Erik Reppel, head of engineering at Coinbase Developer Platform. He used the term “pay-per-crawl” to describe the problem being solved.
“Think of it as like paywalls for scrapers,” Reppel said in an interview. “ So x402 is a great standard for situations where an AI agent needs access to data or access to content in order to make more informed, better decisions.”
Imagine an agent pulling the latest market data, commissioning a design from an AI art model, or subscribing to a live data feed for sports or finance, Coinbase said in a blog about x402 Bizarre.
Some of the first projects listed include Prixe, a stock price API allowing agents to create up-to-date financial reports, and various image and video generation endpoints.
As more services are added, the possibilities for autonomous workflows will only expand, Reppel said.
“Really any digital goods or any digital piece of media can be paid for with X 402,” he said.
