OKX has introduced an open payments protocol for AI agents, joining a broader push by crypto and payments firms to build infrastructure that enables software agents to transact with minimal human involvement.
The new cross-chain Agent Payments Protocol (APP) is designed to support autonomous agent activity, including agent-to-agent payments, recurring and top-up payment flows, and other automated financial processes. OKX said the system also allows agents to negotiate terms, hold funds in escrow and release payments once tasks are verified.
The framework is built around OKX’s self-custodial Agentic Wallet and Payment SDK, with support for its X Layer network and broader cross-chain functionality. The company positions the protocol as a step toward enabling AI agents to move beyond simple payment requests into more independent commercial interactions.
The launch comes amid growing competition to establish payment rails for machine-driven commerce. Google is advancing its AP2 protocol, Coinbase has introduced the x402 standard, and efforts tied to Visa and Stripe are also gaining traction in the race to define how AI agents transact.
OKX pushes toward full AI-driven commerce
OKX is positioning its Agent Payments Protocol (APP) as a complete commerce layer rather than just a payment tool.
The company said AI agents can request real-time market data, with services responding via an HTTP 402 payment request. Agents can then pay per query, with settlement handled automatically.
Beyond simple transactions, agents can also delegate tasks—hiring specialized sub-agents to carry out research or other functions. APP facilitates this by opening an escrow account, with funds released only after the task is completed and verified, enabling more autonomous, end-to-end commercial workflows.
Developers can also integrate OKX’s payment tools on its X Layer network, where the company says certain stablecoin transfers can be executed without gas fees.
The broader push to enable machine-driven payments could further boost stablecoin adoption. According to Bernstein, stablecoins are well-suited for machine-to-machine transactions, as they make microtransactions economically viable and allow for programmable, conditional payments between software agents without human intervention.
