@x402sentinel/langchain

Sentinel tool for LangChain agents. Every x402 payment your chain makes is audited.

Install

npm install @x402sentinel/langchain @x402sentinel/x402

Usage

import { SentinelX402Tool } from "@x402sentinel/langchain";

const tools = [
  new SentinelX402Tool({ agentId: "research-agent" }),
];

// Use in your LangChain agent — all x402 payments tracked

With API key

const tools = [
  new SentinelX402Tool({
    agentId: "research-agent",
    apiKey: "your-api-key",
  }),
];

How it works

SentinelX402Tool extends LangChain's Tool class. When an agent calls it with a URL, it makes the request through Sentinel-wrapped fetch. Every x402 payment is automatically logged with full audit data.
