x402 AI payment network gets governance body with Circle, Google as members

The Linux Foundation has formed a governance body for the x402 protocol, an AI payment network developed by Coinbase, with 40 members including Circle, Google, AWS, and American Express. The coalition aims to standardize machine-to-machine payments as AI agents increasingly participate in the global economy, with x402 transactions on Base surging to over 100 million in Q1 2026.

x402, the Coinbase-developed protocol that lets AI agents make autonomous payments, now has a governance body stitched together by the Linux Foundation. A total of 40 fintech players from the TradFi as well as the crypto space have joined this governance body as members, looking to standardize practices and rules around machine-to-machine payments. The idea to form this governance body started to take shape in April. In the last three months platforms like Google https://thecoinheadlines.com/crypto/pentagon-flagged-china-firms-tap-google-openai-via-singapore-ft/article-25782/ , Circle https://thecoinheadlines.com/tech-and-ai/circle-taps-elliptic-to-test-agentic-ai-for-crypto-compliance-risk-management/article-25560/ , AWS https://thecoinheadlines.com/crypto/coinbase-partners-with-aws-to-enable-ai-agent-micropayments-using-usdc/article-17358/ , American Express, Coinbase https://thecoinheadlines.com/crypto/coinbase-wins-uk-approval-to-become-an-everything-exchange/article-25141/ , and NEAR Foundation joined the initiative led by the Linux Foundation. Collectively, these 40 companies will work to set standard for AI payments over the HTTP protocol. The Linux Foundation, meanwhile, will serve as a neutral governance force to lead the coalition. To advance the growth of the x402 protocol, these member companies plan to structure how AI agents will eventually use this technology to support multiple payment types — ranging from traditional cards to stablecoins https://thecoinheadlines.com/crypto/us-uk-set-to-make-stablecoins-key-part-of-cross-border-settlements/article-26059/ . “AI agents and automated systems are becoming active participants in the global economy, yet they have lacked a native, secure way to transact,” said Jim Zemlin, CEO of the Linux Foundation. “By bringing together leading companies across finance, technology and more, we’re ensuring that the payment layer of the internet remains neutral, highly interoperable and ready to support digital commerce.” Coinbase https://thecoinheadlines.com/crypto/binance-xrp-whale-outflows-hit-57-6-percent-while-coinbase-whales-remain-inactive/article-19536/ had released the x402 protocol for agentic AI payments last year in May. In the last one year, multiple crypto and fintech players including Algorand, Circle, Stripe, and Stellar integrated the protocol with their platforms to support AI-to-AI financial transactions, without any intervention from humans. While Coinbase’s Base blockchain serves as the primary, free of cost settlement chain for x402 payments, in May Solana claimed https://thecoinheadlines.com/blockchain/65-percent-of-ai-commerce-under-control-solana-claims-x402-dominance/article-20108/ that it controlled 65 percent of x402-enabled agentic AI payments. Since its launch, the protocol has already witnessed widespread adoption especially in the crypto space — showing signs of an upward momentum going forward. “x402 is built-in to existing HTTP requests, with no additional communication required. Add one line of code to require payment for each incoming request. If a request arrives without payment, the server responds with HTTP 402, prompting the client to pay and retry,” the website of the protocol explains.

As per Chainalysis, agentic transactions via x402 on Base spiked to over 100 million in Q1 2026 from near-zero in mid-2025.

At present, the x402 protocol is facing competition from Google’s Agent Payments Protocol AP2 , Stripe’s Machine Payments Protocol MPP , and OpenAI+Stripe’s Agentic Commerce Protocol ACP . These protocols are letting AI agents pay for cryptographic mandates, streaming micropayments, and e-commerce shopping respectively.
