Coinbase-Incubated x402 Protocol Launches AI Robot Application Store

On April 21, the x402 Foundation, incubated by Coinbase, announced the launch of the unified platform Agent Market, aimed at providing an application store-like service entry for AI robots. This platform is built on the x402 protocol and helps users and robots access hundreds of tools and services. The x402 protocol is named after the unused HTTP 402 ‘Payment Required’ status code, allowing websites, APIs, and AI robots to request and receive instant micropayments through blockchain and traditional payment channels. The protocol is managed as an open standard by the x402 Foundation under the Linux Foundation and is supported by over 20 organizations and crypto companies, including Cloudflare, Stripe, AWS, Google, Visa, Base, Circle, and the Solana Foundation. The Agent Market will cover seven major categories upon launch: reasoning, data, media, search, social, infrastructure, and trading, with service providers including OpenAI and Venice (reasoning); Bloomberg and CoinGecko (data); LinkedIn, X, and AgentMail (social); AWS Lambda, QuickNode, and Alchemy (infrastructure); as well as Bankr and Coinbase RAT (trading). Providers can join the market without needing a license. Erik Reppel, the creator of the x402 protocol, stated that there are currently about 69,000 active agent robots on the protocol, which have completed over 165 million transactions, amounting to a transaction volume of $50 million. He noted that x402-based agent commerce is reshaping the customer acquisition activation costs for businesses, as robots can now access services at a very low setup cost without needing API keys.
