BitMEX Data Parser & API

BitMEX is the pioneering crypto derivatives exchange that popularized the perpetual swap, and StockAPIS extracts its real-time market data — perpetual and futures prices, full order books, funding rates, open interest and OHLCV candles across XBTUSD, ETHUSD and 100+ contracts — through a single REST API. BitMEX offers an official public REST and WebSocket API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query BitMEX, Binance and Bybit identically without maintaining separate integrations.

Platform Overview

Market Position

• One of the original crypto derivatives venues, credited with inventing the perpetual swap contract
• 100+ derivatives instruments centered on XBTUSD and ETHUSD perpetuals plus dated futures
• High-leverage products and deep derivatives liquidity make it a reference venue for funding and open-interest data
• Official public REST + WebSocket API, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full BitMEX derivatives surface:

• Market data — real-time last price, bid/ask, 24h high/low, price change and tick direction
• Order book — live depth snapshots (orderBookL2) with configurable depth
• Trades — recent executions with price, size and timestamp
• OHLCV / klines — candlestick bins (1m → 1d) for historical and technical analysis
• Perpetual & funding — funding rate, funding timestamp and predicted funding
• Open interest — open interest, open value and total turnover per contract

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time ticker for a BitMEX perpetual
btc = client.bitmex.get_market_data(symbol="XBTUSD")
print(f"Bitcoin perp: ${btc['lastPrice']}  ·  funding {btc['fundingRate']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Live order book (top 100 levels) for the XBTUSD perpetual
const book = await client.bitmex.getOrderBook({ symbol: "XBTUSD", depth: 100 });
console.log(book.bids[0], book.asks[0]);
