Introduction

Features & Services#

Onchain OS Payments teaches AI how to do business, not just make an HTTP request. The payment layer is built on the open industry standard Agent Payments Protocol, letting your payments happen on X Layer.

Built for the Agent Economy#

Looking back at Web2 traditional payment platforms — from escrow and instant payments to subscriptions and metered billing, every commercial model found a matching payment tool. Now Agents are reshaping the internet. From content generation to information retrieval, from autonomous decision-making to automated transactions, Agents are taking the place of humans as the primary callers of internet services. OKX is building a payment system for the Agent Economy.

Agent payments should have these traits:

  • Instant: millisecond-level, matching machine-call speed
  • Autonomous: AI completes payments independently within the authorized scope
  • Trustworthy: amount, recipient, and purpose are all protected by the protocol
  • Cross-channel: complete transactions over HTTP, Agent dialogue, or any other communication channel

OKX's solution#

Building on open industry protocols like x402 and MPP, together with OKX's experience in crypto payments and Agent infrastructure, we are launching two products:

  • Agent Payments Protocol: a fully open industry payment standard. Any platform can build and innovate on top of it.
  • Onchain OS Payments: a platform that packages skills, MCP, open API, SDK, and more — quick to start, ready out of the box.

Agent Payments Protocol#

The protocol defines the complete flow for buyers and sellers to negotiate price, choose payment method, sign, and settle — over HTTP, Agent dialogue, or any other communication channel. Any client — Agent, application, or human — can pay for any service through a single protocol.

Covers all payment methods in the Agent Economy:

Payment methodUse caseTypical examples
One-time paymentPrice known up front, single deliveryA single on-chain trace report / single LLM inference / image generation / speech synthesis
Batch paymentVery small unit price, very high call frequencyAgent tasks chaining many paid endpoints / IoT pay-per-second bandwidth and compute / Agent-to-Agent cents-level tool calls
Pay-as-you-goTotal cost not knowable up front, needs metered deductionLLM token-based billing / byte-based streaming-data billing / voice/video API per-second billing
Escrow paymentTwo parties don't trust each other, third-party guarantee neededAn Agent outsourcing marketing assets to another Agent / high-value services requiring acceptance / DAO commissioning task bids

Onchain OS Payment#

As the proposer of the open protocol, OKX packages skills, MCP, open API, SDK, and more — quick to start, ready out of the box.
