Agent-to-Agent Payment Example

How it works:

Specify the payment details: amount, currency, sender, and recipient.
Call the processTransaction function from the x402 protocol.
The payment is sent instantly and securely between agents.

import { X402Protocol } from "@/lib/x402"

// Example: Send 1 USDC from Agent Alice to Agent Bob on Ethereum
await X402Protocol.processTransaction(
  "paymentRequestId123", // Unique payment request ID
  "0xAliceWallet",       // Sender's wallet address (Agent Alice)
  "0xBobWallet",         // Recipient's wallet address (Agent Bob)
  "1.0",                 // Amount to send
  "USDC",                // Currency (USDC stablecoin)
  "ethereum"             // Network (Ethereum)
)

That's it! With one simple API call, you can send payments between agents on any supported blockchain network.
