Crypto Pro APIs (DefiLlama, CoinGecko, Arkham)

The REI Crypto MCP Server provides AI assistants with access to professional cryptocurrency data APIs through a unified interface. Built by the Rei Network, this implementation connects to DefiLlama Pro, CoinGecko Pro, and Arkham Intelligence APIs, offering tools for querying token prices, market data, blockchain analytics, and on-chain intelligence. The server exposes a comprehensive set of endpoints for tracking DeFi protocols, monitoring token performance, analyzing wallet activities, and accessing historical price data. Users can deploy the servers themselves with their own API keys or use them without keys through the Rei Network's hosted service, making it particularly valuable for crypto researchers, traders, and analysts who need real-time blockchain data during AI-assisted workflows.
