Huobi

Overview

Huobi (HTX) provides spot trading and market data. Public market data works without auth (verified live, 100KB+ ticker dump); trading needs an API key.

Quick Start

Market tickers — keyless (verified live):

curl "https://api.huobi.pro/market/tickers"

{
  "status": "ok",
  "data": [
    { "symbol": "btcusdt", "open": 68000.0, "close": 68200.5, "high": 69000.0, "low": 67500.0, "amount": 12345.6 }
  ]
}

Klines / depth:

curl "https://api.huobi.pro/market/history/kline?symbol=btcusdt&period=1day"
curl "https://api.huobi.pro/market/depth?symbol=btcusdt&type=step0"

Authentication

• Public market endpoints: keyless (verified).
• Trading: register at htx.com → API key (HMAC-signed requests).

Rate Limits & Notes

• Public data: rate-limited per the docs (be polite).
• Symbols use btcusdt style (lowercase, no dash).
• The exchange rebranded to HTX — the API host remains api.huobi.pro.
