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:
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.
