Where can I find my API key?
If you do not have an account yet, you may sign up for one here. It is free to create an account and no credit card is required. As soon as you create your account, you'll be able to find your API key by logging in at data.nasdaq.com and going to your Account Settings.
When you sign up for an account, you will be asked your purpose for using Nasdaq Data Link (Business, Academic or Personal). Please ensure that you select the most appropriate purpose for you.
