Crypto Categories API
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.
