#altcoins

Live spot market data from MEXC, a top centralised crypto exchange known for listing the widest range of altcoins and new tokens first. The ticker endpoint returns a symbol's 24h last price, bid/ask, high/low, volume and change. The tickers endpoint returns the top symbols by 24h quote volume. The movers endpoint returns the biggest 24h gainers or losers among liquid pairs — the altcoin-momentum view MEXC is watched for. Read live from MEXC, nothing stored. This is MEXC's own spot ticker and altcoin-momentum layer — a distinct centralised-exchange venue, separate from other exchange feeds and from DEX, lending and oracle APIs.

Live spot-market data from KuCoin, one of the largest crypto exchanges and the best-known venue for altcoins, via its public API. KuCoin lists over a thousand trading pairs, so its signature is breadth. Get a pair's full 24-hour snapshot: last price, best bid and ask, high, low, the 24-hour change in price and percent, the base and quote volume, the 24-hour average price and the taker and maker fee. Pull the entire board — every KuCoin pair in one call with its last price and 24-hour change. Get the top of the order book with the spread. Read OHLCV candles at any interval. Live, no key, nothing stored. Distinct from Coinbase, Bitstamp, OKX, Gate.io, Bitfinex, Gemini, Kraken and Bybit venue APIs and from aggregated feeds — this is KuCoin's own ticker, full pair board, order book and candles. Perfect for trading, charting and market-data apps.

Live market data from Gate.io, one of the largest crypto exchanges by listed assets, served from its public v4 API — no key, nothing cached. Gate.io lists thousands of trading pairs, far more than mainstream venues, so it is where new and long-tail altcoins trade. The ticker endpoint returns a pair's snapshot: last price, best bid and ask, 24-hour change percentage, base and quote volume and 24-hour high/low. The tickers endpoint returns every one of Gate.io's roughly 2,200 pairs in one call, sortable by 24-hour change or volume — a sweep of the whole altcoin market. The candles endpoint returns OHLC candlesticks at an interval you choose, from ten seconds to one month. The currency endpoint is Gate.io's distinctive piece: for any coin it returns the deposit and withdrawal status across every blockchain it supports — whether deposits and withdrawals are enabled, on which chains, and whether the asset is delisted or trade-disabled — the operational data a wallet or exchange integration needs before moving funds. Everything is Gate.io's live venue data, nothing stored. Distinct from Coinbase, Bitstamp, OKX and Kraken venue APIs — this is Gate.io's deep altcoin order flow and its per-chain deposit/withdrawal status. 4 endpoints, no key on our side, real-time.

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.
