X402 Mcp
Connects Claude to 177 crypto market intelligence endpoints from Carbon & Cashmere's API using automatic USDC micropayments. You get analyzed crypto news with sentiment scores, stablecoin supply data, Bitcoin on-chain metrics, Bittensor miner leaderboards, and research tools priced $0.003 to $0.50 per call. Payment happens via x402 protocol: your agent triggers an API call, the MCP server signs a USDC payment from your local EVM wallet (Base/Polygon/Arbitrum), and you get the data back. No subscriptions or API keys. Exposes the top 100 revenue-generating endpoints by default to avoid overwhelming Claude's tool selection. Useful when you need real-time crypto intelligence without managing API credentials or pre-purchasing access tiers.
