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.

Live market data for crypto sectors and narratives — the themes the market actually trades, not single coins. Served from the public CoinGecko categories feed (no key, nothing cached), it ranks hundreds of sectors: Smart Contract Platforms, Layer 1s and Layer 2s, Memes, Artificial Intelligence, Real-World Assets, DePIN, Gaming, DeFi, Liquid Staking and many more. For each category it gives the total market capitalisation, the 24-hour market-cap change, the 24-hour trading volume and the three largest coins in that sector — so you can see, for example, that the Meme sector is roughly a $30B market led by Dogecoin and Shiba Inu, and which narratives are pumping or bleeding today. The categories endpoint ranks every sector and can be sorted by market cap, 24-hour change or volume; the category endpoint returns one sector by id or name with its market-cap rank and description; the movers endpoint surfaces the top gaining and losing narratives over the last 24 hours, filtered to real sectors so micro-cap dust does not distort the board. This is the sector-rotation and narrative-tracking layer for any crypto research, screener, portfolio or dashboard app — which themes hold the money and which are moving. Live from CoinGecko, nothing stored. Distinct from single-coin price, market-cap and mover APIs — this is the market by sector and narrative. 4 endpoints.
