🤖 AgentPay - AI Services Marketplace with x402

SKALE x402 Hackathon Submission

Pay-per-request AI services powered by x402 protocol on SKALE Network.

🎯 Problem

Current AI service payments are broken:

• Monthly subscriptions for occasional use
• High minimum payments
• No programmatic payment support
• AI agents can't pay for services autonomously

💡 Solution

AgentPay enables instant, per-request payments for AI services using x402:

// Server: Accept payment with one line
app.get('/api/analyze', x402({ price: '0.001', token: 'USDC' }), analyzeHandler);

// Client: AI agent pays automatically
const result = await x402Client.request('/api/analyze', { data });

✨ Features

• Pay-per-request: Only pay for what you use
• AI Agent Ready: Autonomous payments for AI-to-AI services
• Zero Gas on SKALE: Free transactions on SKALE Network
• Multi-token Support: USDC, ETH, SKL tokens
• Instant Settlement: No waiting, immediate access
