Coinbase Incubated x402 Protocol Launches AI Agent App Store Agent.market

Odaily News The x402 protocol, incubated by Coinbase, has announced the launch of a unified platform called Agent.market, positioned as an "AI Agent App Store" for centrally showcasing and integrating various tools and services built on the protocol. According to the introduction, Agent.market already covers seven major categories at launch: inference, data, media, search, social, infrastructure, and trading. It integrates service providers including OpenAI, Bloomberg, CoinGecko, LinkedIn, X, and AWS Lambda, and supports permissionless integration.

Erik Reppel, Engineering Lead at Coinbase Developer Platform, stated that the platform is essentially "an app store for agents." Currently, there are approximately 69,000 active agents on the x402 network, which have cumulatively completed over 165 million transactions, with a transaction volume reaching $50 million. Most services on Agent.market adopt a pay-per-use model, with some charging an "agentic premium" for AI agents. However, costs can be reduced through subscriptions in high-frequency usage scenarios. Meanwhile, the "agent economy" based on x402 is lowering customer acquisition and integration costs for businesses, unlocking previously constrained demand due to API keys, subscriptions, and micro-payment mechanisms.

The x402 protocol is named after the HTTP 402 "Payment Required" status code, enabling websites, APIs, and AI agents to conduct instant micropayments via blockchain and traditional payment channels. The protocol is governed as an open standard by the x402 Foundation under the Linux Foundation and has received support from over 20 technology and crypto institutions including Cloudflare, Stripe, Amazon Web Services, Google, and Visa.
