Under the hood it pays [Superhighway](https://api-production-17e1.up.railway.app)\n**$0.001 per search in USDC** via the [x402](https://x402.org) protocol, using *your*\nwallet — no API key, no signup, no human in the loop.\n\n## Install\n\nAdd to your MCP client config (e.g. Claude Desktop's `claude_desktop_config.json`):\n\n```json\n{\n  \"mcpServers\": {\n    \"superhighway\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"github:patwalls/superhighway-mcp\"],\n      \"env\": {\n        \"AGENT_PRIVATE_KEY\": \"0xYOUR_FUNDED_BASE_WALLET_KEY\",\n        \"X402_NETWORK\": \"base\"\n      }\n    }\n  }\n}\n```\n\nRestart your client. The agent now has three tools that do the whole search job — **web_search** (live, ranked results), **news_search** (recent articles with dates), and **scrape** (read any URL as clean markdown). Find it, read it, pay per call.\n\n## Wallet\n\n`AGENT_PRIVATE_KEY` is a wallet you control, funded with a little **USDC on Base**\n(each search costs $0.001; gas is covered by the facilitator, so you don't need ETH).\nThe key only ever signs tiny USDC payments — keep it to a small balance.\n\nWant to try free first? Set `X402_NETWORK=base-sepolia` and fund the wallet from a\n[Base Sepolia faucet](https://faucet.circle.com) to pay in test USDC.\n\n## What you get\n\n`web_search` (web) and `news_search` (recent news) each return results as JSON:\n\n```json\n{ \"query\": \"...\", \"count\": 5, \"results\": [ { \"title\": \"...\", \"url\": \"...\", \"description\": \"...\" } ] }\n```\n\n---\n\nPowered by [Superhighway](https://api-production-17e1.up.railway.app) — the web-search API agents pay for.\n"}
