Global Crypto Market API
Live aggregate data for the whole cryptocurrency market — the top-down view, not a single coin, exchange or trading pair, powered by the public CoinGecko global feed, no key, nothing stored. The overview endpoint returns the combined market capitalisation of all crypto, the total 24-hour trading volume, the market-wide 24-hour cap change, the number of active cryptocurrencies and markets, and the ongoing / upcoming / ended ICO counts. The dominance endpoint returns each leading coin's share of total market cap — Bitcoin dominance, Ether dominance, the stablecoin share and the long-tail rest — the single most-watched gauge of where money sits in crypto. The defi endpoint returns the decentralized-finance sub-market: its market cap, its share of total crypto, its 24-hour volume and the largest DeFi token. Track total market cap, BTC dominance and the DeFi share as live JSON. This is the whole-market aggregate cut — distinct from the single-coin, single-exchange and cross-exchange coin-markets APIs in the catalogue.
