In order to make your Binance API read only, there are a few steps you need to take. First, you need to log into your Binance account and go to the settings page. Next, click on the “API” tab and then click on the “Create New Key” button. A pop-up will appear asking you to set a label for the key and select the permissions you want to set. Make sure the “Enable Trading” permission is not selected and then click on the “Create” button.
Your new key will be generated and displayed on the screen. Copy this key and save it in a safe place. Finally, go back to the settings page and click on the “Disable Enable Withdrawals” button. This will ensure that your API key can only be used for reading data and cannot be used to make any trades or withdrawals.
