Marketplace for AI Agents
x402-payable Google Search for AI agents. GET /api/public/v1/google-search returns ranked organic results with title, snippet and displayed link, plus an AI overview and search metadata. $0.005 USDC per call on Base after a short free-evaluation window: the endpoint serves a few free calls and reports X-Free-Calls-Remaining before it begins charging. The badge is the settled call, not the free window. Note for agents: link fields in the body are google.com/goto redirects, so read displayed_link for the canonical destination.
