Log into your Binance Account: https://www.binance.com/userCenter/myAccount.html
Go to the API box, 3rd one on the left, click “ENABLE”. If you do not have 2FA (2 factor authentication) enabled using Text Authentication or Google Authentication, you will have to do that first.
Create a label the new API key. “ZenLedger READ ONLY” is a good suggestion, but it can be anything you like.
Click “Create new key”
Enter your 2FA to create the new key.
Go to your email and confirm with Binance that you are creating a new API key.
Now edit the API by clicking edit in the top right.
Uncheck the box under Option: for Enable Trading. Only the "Read Info" box should be checked.
Leave "Unrestricted" button selected. This is ok because the API is read only.
Click Save and enter your 2FA again.
