This connects your AI agent to a searchable index of 14,000+ x402-enabled HTTP APIs, all payable with USDC on Base. Each search costs $0.01 and runs against endpoints that support the x402 protocol for machine-to-machine payments. You get back structured results with endpoint URLs, pricing metadata, network info, and relevance scores. Use it when you need to discover blockchain, DeFi, or crypto APIs on the fly without manually hunting through docs or setting up individual API keys. It works with Claude Desktop, Cursor, Windsurf, and Python frameworks like LangChain. You'll need a wallet private key and a small USDC balance on Base mainnet to run queries.
