Overview
Huobi (now HTX) is a major global cryptocurrency exchange API headquartered in Seychelles, offering access to hundreds of spot and futures trading pairs. It provides real-time market depth, candlestick data, and trade history for currencies including BTC, ETH, and many altcoins. An API key is required for trading operations, but some public market endpoints can be accessed without authentication.
Beginner Tip
Start with the public market-data endpoints — such as GET /market/detail/merged — which do not require an API key, to familiarize yourself with the response structure before setting up authentication.
