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 method | Use case | Typical examples |
|---|---|---|
| One-time payment | Price known up front, single delivery | A single on-chain trace report / single LLM inference / image generation / speech synthesis |
| Batch payment | Very small unit price, very high call frequency | Agent tasks chaining many paid endpoints / IoT pay-per-second bandwidth and compute / Agent-to-Agent cents-level tool calls |
| Pay-as-you-go | Total cost not knowable up front, needs metered deduction | LLM token-based billing / byte-based streaming-data billing / voice/video API per-second billing |
| Escrow payment | Two parties don't trust each other, third-party guarantee needed | An Agent outsourcing marketing assets to another Agent / high-value services requiring acceptance / DAO commissioning task bids |
