X-Agent open-source AI payment control plane xpense, collaborates with OKX to reconstruct the 'autonomous economic execution' architecture BlockBeats News: On July 28th, the Web3 AI ecosystem network X-Agent officially announced the open source of its new infrastructure project xagentAI/xpense after completing the deep integration of OKX Agenetic Wallet and launching the OKX market paid MCP tool. This project is positioned as the Payment Control Plan for AI Agents, filling the core control layer gap in AI's autonomous consumption, budget risk control, and delivery verification. Breaking through the bottleneck of "hanging a wallet" and solving the risk control problem of machine payment, the existing HTTP 402, x402, MPP, MCP, and OKX Agenetic Wallet provide signature and micro payment channels, but still lack upper level control in the scenario of "machine autonomous consumption". Xpense aims to address key engineering and risk management challenges: who decides the funding amount when agents need to purchase data or computing power in real-time during task execution, how to prevent duplicate charges, and how to verify whether paid services are truly delivered. The seven step deterministic control process and dual state machine design proposed by xpense is the core pipeline of "Intent → Policy → Route → Pay → Deliver → Verify → Account", and four engineering principles are established: non trust root of the big model: the big model only proposes consumption suggestions, and fund deduction and signature input are strictly controlled by the policy engine and budget lock atomization. Payment and delivery dual state machine isolation: Decoupling "whether funds are settled" and "whether services are returned" to ensure clear traceability, refund, and dispute resolution paths in case of network timeout or non delivery. Payment Perception Capability Router: A comprehensive evaluation tool for price, latency, delivery quality, and data privacy to create an "OpenRouter" in the field of AI capabilities. Deep integration with the OKX ecosystem: relying on OKX Agenetic Wallet's TEE key isolation and custody, as well as x402 gas free USDC settlement, to ensure hardware level key security and low-cost micro payments. Building an auditable and interpretable Agent economy, xpense, converges every financial behavior of the Agent into a unique chain of facts that includes intent, decision, attempt, receipt, and delivery, making it possible for enterprise level risk control, billing traceability, and attribution. X-Agent is accelerating the evolution of AI from an auxiliary software for human pre recharge and payment to an independent economic entity that can independently consume, provide services, and earn profits.
