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 -request GET
--url 'https://open-api-v4.coinglass.com/api/futures/supported-coins'
--header 'accept: application/json'\
--header 'CG-API-KEY: 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. ❗
