2. What Do You Need Before Using CoinGlass API?
Before getting started, you only need three things:
👉A CoinGlass account
👉A CoinGlass API Key
👉An environment capable of sending HTTP requests (such as Python, Node.js, or curl)
If you don’t have an API Key yet, you can apply for one on the CoinGlass API page.
3. Get Your CoinGlass API Key
🤖Log in to CoinGlass
📊Access the API management page
Create and copy your API Key
👉 Once you obtain your API Key, you can immediately start calling CoinGlass Open API v4 with no additional configuration required.
⚠️ Please keep your API Key secure and do not share it publicly.
4. Send Your First API Request
CoinGlass API v4 (Open API v4) uses a standard HTTP REST interface.
You can access the API by including your API Key in the request headers.
📘 Refer to the CoinGlass API documentation for more details.
Python Example
import requests
BASE_URL = "https://open-api-v4.coinglass.com"/
ENDPOINT = "/api/futures/open-interest/history"
headers = {
"accept": "application/json",
"CG-API-KEY": "YOUR_API_KEY_HERE"
}
params = {
"exchange": "Binance",
"symbol": "BTCUSDT",
"interval": "1d"
}
response = requests.get(BASE_URL + ENDPOINT, headers=headers, params=params)
print(response.text)
If the request is successful, you will immediately receive historical open interest data for Binance BTCUSDT, which means you have successfully connected to CoinGlass API.
