AI Payment

Empowering AI Agents for Autonomous Transactions, Ushering in a New Era of Web3 Payments

An automated micropayment solution built on the x402 protocol. With MCP protocol bridging, AI agents can perform global payments with zero manual intervention, reshaping the machine economy ecosystem.

Product Features

A Foundational Payment Architecture Designed for Machines and Automated Programs

Fully Automated with Zero Manual InterventionAgents automatically parse the 402 response, extract payment parameters, and retry the request with a locally signed payload, fully automated without manual intervention.

Instant Settlement with No Gas FeesBased on the EIP-3009 protocol, agents only need to sign an authorization, while Gate-facilitator handles on-chain broadcasting to enable seamless micropayments.

Chain-Agnostic Global CompatibilityThe protocol architecture is fully decoupled from any single network, allowing seamless movement across major networks and stablecoin ecosystems while avoiding complex cross-chain processes.

Native MCP Protocol BridgingProvide standardized Model Context Protocol (MCP) integration for AI agents, enabling easy access to order placement, signing, payment, and other functions.

Business Process

One Request, Instant Settlement

Payment Trigger

The agent requests a service. The merchant determines payment is required and returns an HTTP 402 response with payment details.

Agent Signature

The agent parses the parameters and uses the local wallet private key to encrypt and sign the transfer information (no gas fees required).

Verification

The agent retries the request with the signature. Gate Pay verifies the signature and order consistency.

On-Chain Delivery

After verification, the merchant delivers the service, and the Gate-facilitator asynchronously broadcasts the transaction on-chain.

Application Scenarios

Redefine Future Business Scenarios

Ideal for innovative fields where traditional payment methods, such as micropayments or pay-per-use billing, cannot effectively operate.

API Services Billed on Demand

Charge small amounts of USDC in real time for each API call. Developers do not need to purchase subscriptions in advance, lowering the barrier to use and enabling instant monetization.

Large model usage fees

Real-time financial data APIs

Agent-to-Agent Transactions

Enable autonomous buying and selling of data, compute, or services between AI agents, creating micro digital economies without manual intervention.

Agent compute crowdsourcing

Automated supply chain matching

Content and Digital Asset Paywalls

Build a pay-per-use model where user agents automatically pay fees when accessing restricted content, with no account registration required.

Premium research sold per report

Decentralized streaming billed by the second
