All requests to the CoinGlass API require authentication using a unique, user-specific API Key.
Requests without a valid API Key or missing headers will be rejected with an authentication error.
🧾 How to Get an API Key
To get started, log in to your account and generate your API Key from your API Key Dashboard.
✅ Example Usage
curl -X GET "https://open-api-v4.coinglass.com/api/futures/supported-coins" \
-H "accept: application/json" \
-H "CG-API-KEY: YOUR_API_KEY"📦 Header Requirement
Every request must include the following HTTP header:
CG-API-KEY: your_api_key_here
If this header is missing or the API Key is invalid, the request will be denied with a 401 Unauthorized error. ❗
