Categories List
A flat identifier map of roughly 856 CoinGecko categories, each as category_id and name. These are the values accepted by the category filter on get_coingecko_coins_markets, so use this to turn a theme into a usable id. It carries no market data at all; for category market caps, 24h change and leading coins use get_coingecko_coins_categories.
