Nasdaq Data Link API Documentation

Welcome to Nasdaq Data Link. You'll find comprehensive guides and documentation to help you start working with Data Link as quickly as possible, as well as support if you get stuck. Let's get started.




You can download the Nasdaq Data Link Python package from PyPI or from GitHub. Follow the installation instructions below.

NOTE: Installation of the Nasdaq Data Link Python package varies depending on your system.

On most systems, the following commands will initiate installation:

pip install nasdaq-data-link
import nasdaqdatalink

On some systems, you may need this command instead:

pip3 install nasdaq-data-link
import nasdaqdatalink

Additionally, you can find detailed installation instructions for Python modules here: Python 3.x.


The Nasdaq Data Link Python module is free but you must have a Nasdaq Data Link API key in order to download data. To get your own API key, you will need to create a free Nasdaq Data Link account and set your API key.

There are two ways to configure the Python SDK to use your API Key:

  • Environment variable
  • Local file

Please read our configuration setup instructions for more details.
