get-coin-history
ChatGPTGet a coin's price, market cap and 24h volume on a specific past date (snapshot at 00:00 UTC). Use this when the user asks what a coin was worth on a given date, e.g. 'BTC price on Jan 1 2024'. Not for current prices (use get-coin-markets) or price ranges over time (use get-coin-market-chart), and not financial advice.
get-coin-market-chart

get-global-market

get-top-gainers-losers
ChatGPTGet the top gaining and top losing coins over a time window and display them in a visual widget. Use this when the user asks what's pumping, dumping, or moving today. Not for a single coin's price (use get-coin-markets). Data only — never frame as a buy/sell signal. Requires a CoinGecko Pro API key.
