Crypto exchange OKX has launched its Agent Payments Protocol (APP), an open standard aimed at facilitating full business cycles for AI-driven transactions, allowing autonomous AI bots to pay for services and manage workflows. This initiative follows similar projects like Coinbase’s x402 and Stripe’s Machine Payments Protocol, reflecting a growing trend in agentic commerce where AI agents not only process payments but also engage in quoting, negotiating, and dispute resolution. APP, which is designed to operate across multiple blockchain platforms including Solana and Ethereum, will also feature escrow functionality to ensure funds are released only once services are delivered. This release builds on OKX’s existing AI tools and is supported by notable partners such as AWS, Alibaba Cloud, and the Ethereum Foundation, positioning APP as a comprehensive solution for autonomous business operations.
OKX: OKX is a global cryptocurrency exchange offering spot, futures, options trading, and Web3 services including wallets and onchain infrastructure across multiple blockchains. It recently launched Onchain OS to bridge AI agents with blockchain execution. In this news, OKX introduced the Agent Payments Protocol to enable AI bots to handle full business cycles from quoting to dispute resolution.
x402: x402 is an open payment protocol developed by Coinbase that enables instant stablecoin payments over HTTP for APIs, apps, and AI agents using the 402 status code. It supports an app store for bots to buy services like data access and cloud infrastructure. The news references it as a precursor to OKX’s more expansive Agent Payments Protocol.
OKX Agentic Wallet: OKX Agentic Wallet is a self-custodial, TEE-secured wallet built for AI agents to autonomously manage onchain assets, sign transactions, and execute across over 20 chains via natural language interfaces like MCP. It enables secure storage and movement for agent workflows. The news notes its integration with the new Agent Payments Protocol for multi-chain business use cases.
Agent Payments Protocol: Agent Payments Protocol is an open standard launched by OKX for AI agents to conduct autonomous commerce including negotiation, escrow, metering, settlement, and disputes across chains like Solana and Ethereum. It includes a Payment SDK for developers using OKX’s X Layer for low-gas transactions and integrates communication protocols like HTTP and XMTP. The news details its rollout as a comprehensive upgrade over prior one-off payment solutions.
Machine Payments Protocol: Machine Payments Protocol is an open standard co-authored by Stripe and Tempo for machine-to-machine payments, allowing AI agents to handle transactions via HTTP 402 responses without traditional cards. It focuses on micropayments and recurring agent payments. OKX’s announcement positions it alongside x402 as an existing but limited agentic payment offering.
Partners: OKX’s Agent Payments Protocol gains support from AWS, Alibaba Cloud, Ethereum Foundation, Solana, Uniswap, and others for cross-chain interoperability.
OKX AI Ecosystem: APP builds on OKX’s recent AI tools including Onchain OS, Agent Trade Kit, and Agentic Wallet for autonomous onchain operations.
Agentic Commerce Trend: Experimentation with AI agent payments is accelerating, with x402 featuring an app store for bot purchases and Stripe’s MPP enabling machine negotiations.
