HTX Spot REST API
The HTX Spot REST API provides HTTP access to reference data (system status, symbols, currencies, chains), market data (klines, tickers, depth, trades, 24h summaries), account and balance information, wallet deposits/withdrawals, sub-user management, spot and conditional order placement and querying, and cross/isolated margin lending. Base hosts are api.huobi.pro and the AWS-optimized api-aws.huobi.pro. Authentication uses AccessKeyId plus an HMAC-SHA256 Signature Version 2 request signature.
