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. ❗

Response Headers:

API-KEY-MAX-LIMIT: Indicates the maximum allowed request limit for your API key (per minute).
API-KEY-USE-LIMIT: Shows the current usage count of your API key (requests made in the current time period).
