Huo Xing Cai Jing reports that x402, a protocol incubated by Coinbase, has launched Agent.market, a unified platform positioned as an “AI Agent App Store” to centrally showcase and connect tools and services built on the protocol. At launch, Agent.market encompasses seven categories: reasoning, data, media, search, social, infrastructure, and trading, integrating service providers such as OpenAI, Bloomberg, CoinGecko, LinkedIn, X, and AWS Lambda, with permissionless access supported. Erik Reppel, Engineering Lead at Coinbase Developer Platform, stated that the platform is essentially an “app store for agents.” Currently, the x402 network hosts approximately 69,000 active agents, with over 165 million transactions completed and a total transaction volume of $50 million. Most services on Agent.market operate on a pay-per-use model, with some charging an “agentic premium” to AI agents, though subscription plans can reduce costs for high-frequency use cases. Meanwhile, the “agent economy” built on x402 is lowering customer acquisition and integration costs for businesses, unlocking previously constrained demand limited by API keys, subscriptions, and micropayment mechanisms. The x402 protocol is named after the HTTP 402 “Payment Required” status code and enables websites, APIs, and AI agents to perform instant micropayments via blockchain and traditional payment channels. Governed as an open standard by the x402 Foundation under the Linux Foundation, the protocol is supported by over 20 technology and crypto organizations, including Cloudflare, Stripe, Amazon Web Services, Google, and Visa.
