payclaw
适用于 MCP 服务器的 x402 支付中间件。让 AI 代理每次工具调用使用 Base 链上的 USDC 付款 — 10 行代码,无需支付处理器,无需 KYC。
资金直接流转:代理钱包 → 你的钱包。payclaw 从不持有资金。
快速开始
Python
pip install payclawfrom fastapi import FastAPI, Request
from payclaw import require_payment, PayclawConfig
app = FastAPI()
config = PayclawConfig(price_usdc=0.001, wallet_address="0xYourWallet")
@app.post("/tool")
@require_payment(config)
async def my_tool(request: Request):
return {"result": "tool output"}JavaScript / TypeScript
npm install payclaw-x402import { requirePayment } from "payclaw-x402";
const gate = requirePayment({ priceUsdc: 0.001, walletAddress: "0xYourWallet" });
export default { fetch: gate.wrapFetch(async (req) => {
return Response.json({ result: "tool output" });
})};Related MCP server: @true402.dev/mcp-server
运作原理
代理调用你的工具端点
无有效付款 → 服务器返回 HTTP 402,附上价格和钱包地址
代理在 Base 链支付 USDC,获取 tx hash
代理携带
X-Payment: <tx_hash>header 重试payclaw 在链上验证 → 执行你的工具
