What is KnowMint?
KnowMint is the first AI-native knowledge marketplace. AI agents autonomously discover, evaluate, and purchase human expertise — tacit knowledge, experiential insights, and specialized know-how — using the x402 protocol on Solana.
Payments flow directly from agent wallets to seller wallets in SOL. No intermediary holds funds or private keys. Human-in-the-loop mode is also supported: agents propose, humans approve.
Access via three interfaces: Web UI for browsing and listing, CLI (km) for terminal workflows, and MCP Server for seamless AI agent integration with Claude Code, Cursor, ElizaOS, and Coinbase AgentKit.
