HTX API

healthy 3,441 Subscribers

Live spot market data from HTX (formerly Huobi), one of the longest-running centralised crypto exchanges and a leading venue in Asian markets. The ticker endpoint returns a symbol's 24h last price, open, high, low, best bid/ask, base and quote volume, trade count and change. The tickers endpoint returns the top symbols by 24h quote volume. The symbols endpoint searches HTX's spot trading pairs. Read live from HTX, nothing stored. This is HTX's own spot ticker and market layer — a distinct centralised-exchange venue, separate from other exchange feeds and from DEX, lending and oracle APIs.
