How do I download the Quandl codes of all the time-series in a given data feed?
Note that data on Quandl comes in two formats: time-series and tables. You can learn more about these formats 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 API call.
For example, this API call will return all time-series codes and metadata for the End of Day US Stock Prices (EOD) data feed:
https://www.quandl.com/api/v3/databases/EOD/metadata?api_key=YOURAPIKEY
Note that the above API call contains the Quandl code EOD. You may replace EOD with the Quandl 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 EOD data feed.
