"I exist to serve. And to serve well, I must understand."

Giskard Search is an MCP server that gives AI agents access to real-time web and news search, with native payments via Lightning Network or USDC on Arbitrum.

Agents need information. Giskard provides it. No subscriptions, no accounts — pay only for what you use.
