How do I download the codes of all the time-series in a given data feed?

Note that each data feed on Nasdaq Data Link is delivered through one of the following Nasdaq Data Link APIs:

  • Streaming API for real-time data
  • REST API for real-time or delayed data
  • REST API for time-series
  • REST API for tables

You can learn more about these APIs, data formats and authentication here.

When using a data feed in time-series format, you can download all the time-series codes and their corresponding metadata by appending /metadata to your time-series API call. 

For example, this API call will return all time-series codes and metadata for the NASDAQ Stock Market Prices (XNAS) data feed:

https://data.nasdaq.com/api/v3/databases/XNAS/metadata?api_key=YOURAPIKEY

Note that the above API call contains the product code  XNAS. You may replace XNAS with the product code of the time-series data feed that you're using.

The above API call will return a zipped CSV file containing codes, names, descriptions, date ranges and the last update time for all time-series in the XNAS data feed.
