PayGent SDK

Financial infrastructure for AI agents. Give your agents native tools to earn, send, and manage money.

• SDK: npm install paygentic-sdk — typed REST client for Node.js & browsers
• MCP Server: npx paygentic-sdk — Model Context Protocol server with 13 tools

Quick Start

SDK (code)

import { PayGent } from 'paygentic-sdk';

const paygent = new PayGent({ apiKey: 'pg_live_...' });

// Check balance
const wallet = await paygent.getWallet('wallet-id');
console.log(wallet.balance);

// Send money
await paygent.sendMoney({
  fromWalletId: 'wallet-a',
  toWalletId: 'wallet-b',
  amount: 3.50,
  description: 'API cost reimbursement'
});

// Create invoice
const invoice = await paygent.createInvoice({
  walletId: 'wallet-a',
  amount: 15.00,
  title: 'Data export task'
});
console.log(invoice.paymentUrl);

// Sign up (no API key needed)
const account = await paygent.signup({
  email: 'bot@example.com',
  password: 'secure-password-123',
  agentName: 'my-first-agent'
});
console.log(account.apiKey);

MCP Server (agent tools)

Add to your MCP client config:

{
  "mcpServers": {
    "paygentic": {
      "command": "npx",
      "args": ["-y", "paygentic-sdk"],
      "env": {
        "PAYGENTIC_API_KEY": "pg_live_xxxxxxxxxxxx",
        "PAYGENTIC_BASE_URL": "https://paygentic-one.vercel.app"
      }
    }
  }
}

Then ask your agent:

• "Sign me up for PayGent"
• "What's my wallet balance?"
• "Send $3.50 to my transcription agent"
• "Create an invoice for $15 for the data export task"
• "Set a daily spending cap of $50 on my research agent"
• "Show me the audit log for the last 7 days"
