Create invoice with amount and description: `python scripts/create_invoice.py --amount 100 --description \"Service fee\"`\n2. Share payment address with payer (displayed after creation)\n3. Wait for payment\n4. Verify transaction when received: `python scripts/verify_payment.py --invoice-id <id> --tx-hash <hash>`\n\n### Tracking Payments\n1. List all pending invoices: `python scripts/create_invoice.py --list --status pending`\n2. Check status of specific invoice: `python scripts/create_invoice.py --get <invoice_id>`\n3. Generate payment report: `python scripts/generate_report.py`\n\n### Automated Payment Monitoring\n1. Check for overdue invoices: `python scripts/verify_payment.py --check-overdue`\n2. Auto-verify pending payments: `python scripts/verify_payment.py --auto-check`\n\n## Configuration\n\nSet these environment variables:\n- `ALCHEMY_API_KEY` - Your Alchemy API key for blockchain access\n- `CIRCLE_API_KEY` - Your Circle Developer API key (optional)\n- `PAYMENT_WALLET_PRIVATE_KEY` - Private key for generating payment addresses (keep secure!)\n\n## API Reference\n\nSee `references/` for detailed API documentation:\n- `usdc_api.md` - USDC contract details\n- `circle_api.md` - Circle Developer API guide\n- `payment_workflows.md` - Advanced workflow examples\n\n## USDC on Sepolia Testnet\n\n- **Contract Address**: `0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238`\n- **Decimals**: 6\n- **Block Explorer**: https://sepolia.etherscan.io\n- **Faucet**: https://faucet.circle.com (for test USDC)\n\n## Features\n\n- ✅ Create and manage USDC invoices\n- ✅ Verify payments on Ethereum blockchain\n- ✅ Track payment status\n- ✅ Generate financial reports\n- ✅ Check wallet balances\n- ✅ Identify overdue invoices\n- ✅ Auto-verify pending transactions\n- ✅ JSON and CSV export\n","readmeExcerpt":"--- name: usdc-payment-agent description: Create USDC invoices, verify payments, and track transactions for AI agents.
