X402 Went From Experiment to Industry Standard In early 2026, x402 crossed a threshold. Stripe launched x402 payments on Base in February, letting developers charge AI agents directly in USDC. Google released the Agent Payments Protocol (AP2), with x402 as its first crypto extension - built alongside Coinbase, MetaMask, and the Ethereum Foundation. Cloudflare co-founded the x402 Foundation with Coinbase and shipped native x402 into their Agents SDK, including paidTool for charging per MCP tool call.
