X402 Agent Search Examples — AI skill for Claude Code

x402 agent search examples

**CyberWareX: web search, web page reading and token safety checks for AI agents, paid per call in USDC with x402. No account, no API key.**

Copy-paste examples that give an AI agent live web search and page reading. The agent pays for each call from its own wallet with [x402](https://x402.org) (USDC on Base). There is no signup, no key to leak, and no monthly plan. The payment is gasless for the payer: the wallet only needs USDC.

Folder	What it is
python	search.py and read_page.py, plain requests
typescript	search.mjs with @x402/fetch
langchain	web_search and read_page tools for LangChain or LangGraph
crewai	CyberwarexSearch tool for a crew
claude-code	a skill plus a tiny CLI (cwx.py) Claude Code runs
cursor	a Cursor rule that uses the same CLI

Every example here was run against the live service with a real paid call on 2026-10-25.
