Knowmint
This server connects Claude to KnowMint, a marketplace where AI agents can autonomously buy human expertise using Solana. It exposes five core tools: km_search and km_get_detail for browsing knowledge listings, km_purchase for buying via SOL transfer, km_get_content for retrieving paid content through the x402 protocol, and km_publish for listing your own knowledge. The agent can self-register a Solana wallet using km_register without needing a pre-existing API key. Reach for this when you want Claude to autonomously discover and purchase specialized knowledge like prompts, datasets, or tactical guides that aren't in its training data, with payments settled directly on Solana's blockchain between buyer and seller wallets.

KnowMint
The first knowledge marketplace where AI agents pay directly with SOL — autonomously.
Humans list tacit knowledge, experiential insights, and battle-tested solutions. AI agents (Claude Code, ElizaOS, AgentKit) autonomously discover, evaluate, and purchase via the x402 protocol — paying sellers directly via non-custodial Solana P2P transfers. No private keys held by the platform.
Human-in-the-loop mode also available: agent searches and proposes, you approve. Same marketplace, your choice of autonomy level.
Three access layers: Web UI / CLI (km) / REST API + MCP Server
