Coinglass API: The Ultimate Crypto Derivatives Data Solution for Traders and Developers
1. What Is Coinglass API?
Coinglass API provides access to one of the most comprehensive sets of crypto derivatives data in the market.
It delivers real-time information on perpetual futures, funding rates, long/short ratios, and liquidation statistics across major exchanges like Binance, OKX, Bybit, and Bitget.
Whether you’re a quantitative trader, data scientist, or Web3 developer, Coinglass API enables you to build data-driven strategies and tools with institutional-grade accuracy.
2. Key Features of Coinglass API
| Feature | Endpoint | Description |
| ------------------------- | ------------------------- | ------------------------------------------------ |
| 📈 **Open Interest Data** | `/futures/openInterest` | Track futures market exposure across exchanges |
| ⚖️ **Long/Short Ratio** | `/futures/longShortRatio` | Measure market sentiment in real time |
| 💧 **Liquidation Data** | `/futures/liquidation` | Monitor major liquidations and volatility spikes |
| 🏦 **Funding Rate** | `/futures/fundingRate` | Analyze trader positioning and funding costs |
| 🌍 **Exchange Data** | `/exchange/list` | Retrieve supported exchanges and contract pairs |
These APIs empower you to monitor the entire crypto derivatives landscape in one unified framework.
3. Why Coinglass API Stands Out
✅ Institutional-Grade Data Quality – Aggregated from top-tier exchanges with high reliability
✅ Real-Time Performance – Sub-second latency ideal for trading systems
✅ Unified Data Structure – Consistent formats across exchanges for seamless comparison
✅ Flexible Integration – Easy access through RESTful endpoints and JSON responses
Coinglass bridges the gap between crypto exchanges and data-driven applications, offering a scalable way to power dashboards, trading bots, and analytics tools.
4. Quick Start: Python Integration Example
import requests
API_KEY = "your_api_key_here"
url = "https://open-api.coinglass.com/api/futures/openInterest?symbol=BTC%22
headers = {
"accept": "application/json",
"coinglassSecret": API_KEY
}
response = requests.get(url, headers=headers)
data = response.json()
print(data)
This example retrieves BTC open interest data across multiple exchanges.
You can easily extend it for other endpoints like funding rates, liquidations, or long/short ratios.
