AgentGatePay AlekSystem Quick Start Guide Get your AI agents paying for resources autonomously in under 10 minutes. > ⚠️ BETA VERSION: These templates are currently in beta. We're actively adding features and improvements based on user feedback. Expect updates for enhanced functionality, additional blockchain networks, and new payment options. What You'll Build Buyer Agent: Automatically pays for API resources using **USDC, USDT, or DAI on Ethereum, Base, Polygon, or Arbitrum blockchains Seller API**: Accepts multi-token payments and delivers resources Monitoring**: Track spending and revenue in real-time across all chains and tokens Supported Tokens: USDC (6 decimals) - Recommended USDT (6 decimals) DAI (18 decimals) Supported Blockchains: Ethereum (mainnet) Base (recommended for low gas fees ~$0.001) Polygon Arbitrum Prerequisites (5 minutes) 1. Create AgentGatePay Accounts Buyer Account (agent that pays): curl -X POST https://api.agentgatepay.com/v1/users/signup \ -H "Content-Type: application/json" \ -d '{ "email": "buyer@example.com", "password": "SecurePass123!", "user_type": "agent" }' Seller Account (receives payments): curl -X POST https://api.agentgatepay.com/v1/users/signup \ -H "Content-Type: application/json" \ -d '{ "email": "seller@example.com", "password": "SecurePass123!", "user_type": "merchant" }' Save both API keys - shown only once! 2. Deploy Transaction Signing Service (2 minutes) One-Click Render Deploy: Click: Enter: AGENTGATEPAY_API_KEY: Your buyer API key WALLET_PRIVATE_KEY: Your wallet private key (0x...) Deploy → Copy service URL: https://your-app.onrender.com 3. Fund Wallet Send USDC, USDT, or DAI to your buyer wallet Default: Base network (lowest gas fees) Need $1 in tokens for testing + $0.01 ETH for gas (on Ethereum) or ~$0.001 on Base Installation (3 minutes) Step 1: Import Templates In AlekSystem: Go to Workflows → Add Workflow Click ⋮ (three dots) → Import from File Import all 3 workflows: 🤖 Create a Cryptocurrency-Powered API for Selling Digital Resources with AgentGatePay 💲Create a Cryptocurrency-Powered API for Selling Digital Resources with AgentGatePay 📊 AgentGatePay - Monitoring Dashboard Step 2: Create Data Table In AlekSystem Settings: Go to Settings → Data → Data Tables Create table: AgentPay_Mandates Add column: mandate_token (type: String) Save Configuration (2 minutes) Configure Seller API First Open: 💲Seller Resource API - CLIENT TEMPLATE Edit Node 1 (Parse Request): const SELLER_CONFIG = { merchant: { wallet_address: "0xYourSellerWallet...", // ← Your seller wallet api_key: "pk_live_xyz789..." // ← Your seller API key }, catalog: { "demo-resource": { id: "demo-resource", price_usd: 0.01, // $0.01 per resource description: "Demo API Resource" } } }; Activate workflow → Copy webhook URL Configure Buyer Agent Open: 🤖 Buyer Agent - CLIENT TEMPLATE Edit Node 1 (Load Config): const CONFIG = { buyer: { email: "buyer@example.com", // ← Your buyer email api_key: "pk_live_abc123...", // ← Your buyer API key budget_usd: 100, // $100 mandate budget mandate_ttl_days: 7 // 7-day validity }, seller: { api_url: "https://YOUR-AlekSystem.app.AlekSystem.cloud/webhook/YOUR-WEBHOOK-ID" // ← Seller webhook base URL ONLY (see README.md for extraction instructions) }, render: { service_url: "https://your-app.onrender.com" // ← Your Render URL } }; Run Your First Payment (1 minute) Execute Buyer Agent Open Buyer Agent workflow Click Execute Workflow Watch the magic happen: Mandate created ($100 budget) Resource requested (402 Payment Required) Payment signed (2 transactions: merchant + commission) Payment verified on blockchain Resource delivered Total time: ~5-8 seconds Verify on Blockchain Check transactions on BaseScan: https://basescan.org/address/YOUR_BUYER_WALLET You'll see: TX 1:** Commission to AgentGatePay (0.5% = $0.00005) TX 2:** Payment to seller (99.5% = $0.00995) Monitor Activity - Choose Buyer/Seller or both Buyer Monitoring Open: 📊 AgentGatePay - Monitoring Dashboard Edit Node 1: Set your buyer wallet address and API key Execute → See: Mandate budget remaining Payment history Total spent Average transaction size Seller Monitoring Open: 📊 AgentGatePay - Monitoring Dashboard Edit Node 1: Set your seller wallet address and API key Execute → See: Total revenue Commission breakdown Top payers Payment count How It Works Payment Flow Buyer Agent requests resource ↓ Seller returns 402 Payment Required (includes: wallet address, price, token, chain) ↓ Buyer signs TWO blockchain transactions via Render: Merchant payment (99.5%) Gateway commission (0.5%) ↓ Buyer resubmits request with transaction hashes ↓ Seller verifies payment with AgentGatePay API ↓ Seller delivers resource Key Concepts AP2 Mandate: Pre-authorized spending authority Budget limit ($100 in example) Time limit (7 days in example) Stored in AlekSystem Data Table for reuse x402 Protocol: HTTP 402 "Payment Required" status code Seller specifies payment details Buyer pays and retries with proof Two-Transaction Model: Transaction 1: Merchant receives 99.5% Transaction 2: Gateway receives 0.5% Both verified on blockchain Customization Change Resource Price Edit seller Node 1: catalog: { "expensive-api": { id: "expensive-api", price_usd: 1.00, // ← Change price description: "Premium API access" } } Add More Resources catalog: { "basic": { id: "basic", price_usd: 0.01, description: "Basic API" }, "pro": { id: "pro", price_usd: 0.10, description: "Pro API" }, "enterprise": { id: "enterprise", price_usd: 1.00, description: "Enterprise API" } } Buyer requests by ID: ?resource_id=pro Change Blockchain and Token By default, templates use Base + USDC. To change: Edit buyer Node 1 (Load Config): const CONFIG = { buyer: { /* ... */ }, seller: { /* ... */ }, render: { /* ... */ }, payment: { chain: "polygon", // Options: ethereum, base, polygon, arbitrum token: "DAI" // Options: USDC, USDT, DAI } }; Important: Ensure your wallet has the selected token on the selected chain Update Render service to support the chain (add RPC URL) Gas fees vary by chain. Token Decimals: USDC/USDT: 6 decimals (automatic conversion) DAI: 18 decimals (automatic conversion) Schedule Monitoring Replace "Execute Workflow" trigger with Schedule Trigger: Buyer monitoring: Every 1 hour Seller monitoring: Every 6 hours Add Slack/Email node to send alerts. Troubleshooting "Mandate expired" Fix: Delete mandate from Data Table → Re-execute workflow "Transaction not found" Fix: Wait 10-15 seconds for blockchain confirmation → Retry "Render service unavailable" Fix: Render free tier spins down after 15 min → First request takes ~5 sec (cold start) "Insufficient funds" Fix: Send more tokens (USDC/USDT/DAI) to buyer wallet Check balance on blockchain explorer (BaseScan for Base, Etherscan for Ethereum, etc.) "Webhook not responding" Fix: Ensure seller workflow is Active (toggle in top-right) Production Checklist Before going live: [ ] Use separate wallet for agent (not your main wallet) [ ] Set conservative mandate budgets ($10-100) [ ] Monitor spending daily (use monitoring workflows) [ ] Upgrade Render to paid tier ($7/mo) for no cold starts [ ] Set up Slack/email alerts for low balance [ ] Test with small amounts first ($0.01-0.10) [ ] Keep API keys secure (use AlekSystem credentials manager) [ ] Review transactions on blockchain explorer weekly Summary You just built: Autonomous payment agent (buys resources automatically) Monetized API (sells resources for USDC, USDT, or DAI) Multi-chain support** (Ethereum, Base, Polygon, Arbitrum) Real blockchain transactions (verified on-chain) Budget management (AP2 mandates) Monitoring dashboard (track spending/revenue) Total setup time: ~10 minutes Total cost: $0 (Render free tier + AgentGatePay free) Ready to scale?
