How exactly do you authenticate you api key?

When searching for a coin (say BTC) how exactly do you authenticate you api key, like what would be the exact link you put in the browser. Im new with APIs and having a hard time with the intro part of the docs and authenticating your api key.

Hi @HUH_Clipz, that’s a good question. Authenticating by putting the API key into your URL is not very secure. What you could do is add the API key to your header when doing a request.
