OKX Data Parser & API

OKX is one of the largest cryptocurrency derivatives exchanges by spot and futures volume, and StockAPIS extracts its real-time market data — spot and futures prices, full order books, OHLCV candles, funding rates, open interest and options chains across 300+ trading pairs — through a single REST API. OKX offers an official public API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query OKX, Binance and Coinbase the same way without maintaining separate integrations.

Platform Overview

Market Position

• A top-5 crypto exchange by both spot and derivatives trading volume
• 300+ trading pairs spanning spot, margin, perpetual swaps, dated futures and options
• A derivatives-first venue with deep liquidity in perpetuals and a full crypto options book
• Official public REST + WebSocket API (the v5 unified-account API), complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full OKX market surface:

• Spot market data — real-time prices, 24h volume, bid/ask spreads and last trade size
• Order book — live depth snapshots with configurable size for bid/ask liquidity analysis
• OHLCV / candles — candlestick data across intervals (1m → 1M) for historical and technical analysis
• Perpetual swaps & futures — mark price, funding rates, open interest and liquidations
• Options — options chains, mark prices and implied volatility for BTC and ETH underlyings
• Instrument info — instrument IDs, contract specs, tick sizes and trading status

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time ticker for an OKX instrument
btc = client.okx.get_market_data(inst_id="BTC-USDT")
print(f"Bitcoin: ${btc['last']}  ·  24h vol {btc['vol24h']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Live order book (top 20 levels) for a perpetual swap
const book = await client.okx.getOrderBook({ instId: "BTC-USDT-SWAP", sz: 20 });
console.log(book.bids[0], book.asks[0]);
