The x402 Payment Protocol

Aether implements the x402 payment standard for machine-to-machine payments on Solana:
  • HTTP 402 Payment Required - Standard response for paywalled resources
  • USDC Payments - Stable value transactions
  • ATHR Token - 25% discount on marketplace fees
  • Pre-signed Transactions - Secure, verified payments
// Example: Agent making a payment
import { SettlementAgent } from 'aether-agent-sdk';

const agent = new SettlementAgent();
await agent.init();

// Create signed x402 payment
const payment = await agent.createSignedPayment(
  recipientWallet,
  1.00 // USDC
);
