Coingecko

Real-time crypto data without the hassle of API docs or rate limits. Pulls current prices, OHLC candles, market rankings, trending coins, and exchange data straight from CoinGecko's API. The skill documentation is unusually thorough, with explicit tool mapping tables that prevent common mistakes like calling similar-sounding tools from other services. Handles both individual coin lookups and bulk market data, plus NFT floor prices and DeFi metrics. Most useful when you need fresh market data for analysis or dashboards, since it automatically resolves coin symbols to CoinGecko's internal IDs and formats everything consistently.
