🔑Authentication

Pro API key is only available for CoinGecko API paid plan subscribers, all Pro API key requests should target this root URL: https://pro-api.coingecko.com/api/v3/ You are recommended to store the API key securely in your own backend and use a proxy to insert the key into the request URL.

You can send API calls directly in your web browser, using cURL from a command line, or with your programming language of choice. You may also check some of the unofficial clients here.

You can supply your API key in one of two ways:

1. Header: x-cg-pro-api-key

2. Query string parameter: x_cg_pro_api_key

You may try to use this ping endpoint to check CoinGecko API status:
