AgentSearch docs
Live web search for AI agents, free by default with no key (up to 25 searches/day per IP through the free relay). When an agent needs the page itself, Extract, Render and Search + Read are paid per call in USDC on Base with standard x402: search $0.008, extract $0.007, render $0.010, search + read $0.015. Failed calls are never charged.
