payclaw
Middleware de pago x402 de fácil integración para servidores MCP. Cobra a agentes de IA por llamada a herramienta usando USDC en la red Base: 10 líneas de código, sin procesador de pagos, sin KYC.
El dinero fluye directamente: billetera del agente → tu billetera. payclaw nunca retiene fondos.
Inicio rápido
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
Cómo funciona
El agente llama a tu endpoint de herramienta
Sin un pago válido → el servidor devuelve HTTP 402 con el precio y la dirección de la billetera
El agente paga USDC en la red Base y obtiene el hash de la transacción
El agente reintenta con el encabezado
X-Payment: <tx_hash>payclaw verifica en la cadena → ejecuta tu herramienta

適用於 MCP 伺服器的 x402 支付中介軟體。讓 AI 代理每次工具呼叫使用 Base 鏈上的 USDC 付款 — 10 行程式碼,無需支付處理器,無需 KYC。
資金直接流轉:Agent 錢包 → 你的錢包。payclaw 從不持有資金。
快速開始
Python
pip install payclawfrom fastapi import FastAPI, Request
from payclaw import require_payment, PayclawConfig
app = FastAPI()
config = PayclawConfig(price_usdc=0.001, wallet_address="0x你的錢包")
@app.post("/tool")
@require_payment(config)
async def my_tool(request: Request):
return {"result": "工具輸出"}JavaScript / TypeScript
npm install payclaw-x402import { requirePayment } from "payclaw-x402";
const gate = requirePayment({ priceUsdc: 0.001, walletAddress: "0x你的錢包" });
export default { fetch: gate.wrapFetch(async (req) => {
return Response.json({ result: "工具輸出" });
})};運作原理
Agent 呼叫你的工具端點
無有效付款 → 伺服器返回 HTTP 402,附上價格和錢包地址
Agent 在 Base 鏈支付 USDC,取得 tx hash
Agent 帶上
X-Payment: <tx_hash>header 重試payclaw 在鏈上驗證 → 執行工具
