安装前可以查看交给 AI 代理的指令内容。
Framework-agnostic agent-to-agent payment infrastructure on Polygon network.
This skill enables AI agents to:
9,416x cheaper than traditional escrow services (Escrow.com charges $28.25 per $100, this costs $0.003).
# Via ClawHub
clawhub install a2a-shib-payments
# Or manual clone
cd ~/clawd/skills
git clone https://github.com/marcus20232023/a2a-shib-payments.git
cd a2a-shib-payments
npm install
Create .env.local:
cp .env.example .env.local
nano .env.local
Required environment variables:
WALLET_PRIVATE_KEY - Your Polygon wallet private keyRPC_URL - Polygon RPC endpoint (default: https://polygon-rpc.com)SHIB_CONTRACT_ADDRESS - SHIB token contract (default: 0x95ad61b0a150d79219dcf64e1e6cc01f0b64c4ce)node a2a-agent-full.js
Agent runs on port 8003 by default.
The agent exposes A2A protocol endpoints that OpenClaw can communicate with:
Agent Card: http://localhost:8003/.well-known/agent-card.json
Example commands from OpenClaw:
// Check balance
const result = await fetch('http://localhost:8003/a2a/jsonrpc', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify({
jsonrpc: '2.0',
method: 'message/send',
params: {
message: {
kind: 'message',
messageId: '1',
role: 'user',
parts: [{kind: 'text', text: 'balance'}]
}
},
id: 1
})
});
// Send payment
// text: 'send 100 SHIB to 0x...'
// Create escrow
// text: 'escrow create 500 SHIB for data purchase payee data-agent'
// Check reputation
// text: 'reputation check data-agent'
Works with:
See INTEGRATION-EXAMPLES.md for detailed integration guides.
// Research agent buys Tesla historical data
const quote = await negotiation.createQuote({
service: 'TSLA 2020-2025 historical data',
price: 500 // SHIB
});
// Counter-offer and accept
await negotiation.counterOffer(quote.id, 'research-agent', 400);
await negotiation.acceptCounter(quote.id, 'data-provider');
// Escrow created automatically
// Create escrow for model training job
const escrow = await escrowSystem.create({
payer: 'startup-agent',
payee: 'ai-trainer',
amount: 1000,
purpose: 'Train GPT-style model',
conditions: {requiresDelivery: true},
timeoutMinutes: 720 // 12 hours
});
