#dominance

Live whole-market crypto data — the bird's-eye view of the market, not single coins — served from the public CoinGecko feed with no key and nothing cached. The global endpoint returns the total crypto market capitalisation and 24-hour volume, the market-cap dominance of the biggest coins (Bitcoin around 56%, Ethereum around 9%), the 24-hour market-cap change, and how many active cryptocurrencies and markets exist. The trending endpoint returns the coins people are searching for most right now — CoinGecko's trending list — with each coin's symbol, market-cap rank, price and 24-hour change. The treasuries endpoint returns the public companies that hold Bitcoin or Ethereum on their balance sheets, ranked by holdings, with each company's coin count and current USD value and the grand total — Strategy alone holds over 800,000 BTC worth tens of billions of dollars. This is the market-overview, sentiment and institutional-flow layer for any crypto dashboard, research, screener or news app. Live from CoinGecko, nothing stored. Distinct from single-coin price, sector and TVL APIs — this is the whole market, what's trending, and who's holding. 4 endpoints.
