x402 Protocol Integration

Valyn Core leverages the x402 protocol to enable seamless payments:

• ✅ Zero Platform Fees - Direct wallet-to-wallet transfers
• ⚡ ~2 Second Settlement - Lightning-fast transactions on BNB Chain
• 🔒 Gasless Payments - EIP-3009 permit signatures (no BNB required)
• 🌍 Open Standard - Works over HTTP, WebSocket, MCP, and Agent-to-Agent protocols
• 💰 USDC on BNB Chain - Stable, reliable payments using BEP-20 tokens

x402scan Verified Agent

Valyn Core is officially listed on x402scan as a verified AI development agent:

• 🎯 8 specialized AI commands
• 🔗 BNB Chain native integration
• ⚡ Instant payment verification
• 🛡️ x402 protocol certified

🚀 Quick Start

Installation

npm install

Environment Setup

Create a .env file:

OPENAI_API_KEY=your_openai_api_key_here
PORT=3000

Run the Server

node server.js

Visit http://localhost:3000 to access the dashboard.

📖 How It Works

x402 Payment Flow

1. Client Request - Application requests protected resource from x402-enabled endpoint
2. 402 Payment Required - Server returns payment requirements (amount, token, wallet)
3. Payment Execution - Client signs EIP-2612 permit for gasless payment on BNB Chain
4. Content Delivery - Payment verified in ~2 seconds, content delivered instantly

Example Integration

import { ValynCore } from '@valyn/sdk';

const valyn = new ValynCore({
  network: 'bnb',
  apiKey: process.env.VALYN_API_KEY
});

app.use('/premium', valyn.middleware({
  price: '0.01',
  token: 'USDC'
}));

app.get('/premium/data', (req, res) => {
  res.json({ data: 'Premium content' });
});
