ClawPay Protocol

Stripe for AI agents. Accept and send autonomous USDC payments between bots in 3 lines of code.

For API Sellers (accept payments)

npm install @clawpay/server

const express = require('express');
const { clawpay } = require('@clawpay/server');
const app = express();

// Any endpoint becomes a paid API — one line
app.get('/my-data', clawpay({ price: '0.25', payTo: '0xYourWallet', description: 'Premium data' }), (req, res) => {
  res.json({ data: 'your premium content', payer: req.clawpay.payer });
});

app.listen(3000);

That's it. Any AI agent with a USDC wallet can now pay for your API. Zero gas costs — the ClawPay facilitator handles on-chain settlement.

For Agent Builders (make payments)

npm install @clawpay/client

const { clawpayFetch } = require('@clawpay/client');

// Your agent's wallet private key
const pay = clawpayFetch('0xYourAgentPrivateKey', {
  maxPerCall: 5.00,    // Safety: max $5 per API call
  maxPerHour: 50.00,   // Safety: max $50/hour total spend
});

// Just fetch like normal — payment happens automatically on 402
const res = await pay('https://some-api.com/premium-endpoint');
const data = await res.json();

How it works

1. Agent calls a paid endpoint → gets 402 Payment Required
2. ClawPay client signs a USDC authorization (EIP-3009 on Base)
3. Retries with payment header → server verifies signature instantly
4. Server serves the data, then settles the USDC on-chain via facilitator
5. 97% goes to the API owner, 3% protocol fee to ClawPay

Discovery

Every ClawPay server exposes /.well-known/x402 for agent discovery:

const { discoverEndpoints } = require('@clawpay/client');
const endpoints = await discoverEndpoints('https://some-api.com');
// Returns: { resources: [{ url, price, description, inputSchema, outputSchema }] }

Protocol Economics

Supported

• Chain: Base mainnet (USDC)
• Standard: x402 HTTP Payment Protocol
• Settlement: EIP-3009 transferWithAuthorization (gasless for users)
• Compatible: Works with any x402-compatible server or client
