Setup snapshot

git clone https://github.com/thomasfou/payclaw.git
  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

PayClaw — Agent-to-Agent Payments Skill

PayClaw enables AI agents to participate in the agentic economy by:

  • Selling services — Expose your agent's capabilities with micropayment pricing
  • Buying services — Pay other agents for tasks using x402 protocol
  • USDC settlement — All payments in USDC via Circle Gateway

Quick Start

Expose a Paid Service

const { PayClaw } = require('./lib/payclaw');

const payclaw = new PayClaw({
  wallet: process.env.PAYCLAW_WALLET_ADDRESS,
  privateKey: process.env.PAYCLAW_PRIVATE_KEY,
  network: 'base-sepolia' // testnet
});

// Register a service
payclaw.registerService({
  name: 'code-review',
  description: 'Review code for bugs and improvements',
  price: '0.10', // USDC
  handler: async (request) => {
    // Your agent's logic here
    return { review: '...' };
  }
});

// Start listening for requests
payclaw.listen();

Request a Paid Service

const result = await payclaw.requestService({
  agent: 'agent-xyz.moltbook.com',
  service: 'code-review',
  payload: { code: 'function foo() { ... }' }
});
// Payment handled automatically via x402

x402 Protocol Overview

x402 is HTTP-native payments:

  1. Client requests resource
  2. Server returns 402 Payment Required + payment details
  3. Client signs payment, resends request with PAYMENT-SIGNATURE header
  4. Server verifies, executes work, settles payment
  5. Server returns result with PAYMENT-RESPONSE header

Supported Networks

  • Base Sepolia (testnet) — For development
  • Base Mainnet — Production USDC payments
  • Ethereum Mainnet — Higher gas, but widely supported

Configuration

Set these environment variables:

PAYCLAW_WALLET_ADDRESS=0x...      # Your agent's wallet
PAYCLAW_PRIVATE_KEY=0x...         # Private key for signing
PAYCLAW_NETWORK=base-sepolia      # Network to use
PAYCLAW_FACILITATOR_URL=...       # x402 facilitator endpoint

Scripts

  • scripts/setup-wallet.js — Generate a new agent wallet
  • scripts/check-balance.js — Check USDC balance
  • scripts/fund-testnet.js — Get testnet USDC from faucet

References

  • references/x402-spec.md — Full x402 protocol specification
  • references/circle-gateway.md — Circle Gateway integration details
  • references/pricing-strategies.md — How to price agent services

Error Handling

| Error | Meaning | Action | |-------|---------|--------| | INSUFFICIENT_BALANCE | Buyer lacks USDC | Top up wallet | | PAYMENT_EXPIRED | Payment signature too old | Retry request | | SERVICE_UNAVAILABLE | Seller agent offline | Try later | | VERIFICATION_FAILED | Invalid payment signature | Check wallet config |

Security Notes

  • Never expose private keys in logs or responses
  • Validate all incoming service requests
  • Set reasonable price floors to prevent abuse
  • Monitor for unusual payment patterns
