How do I use the API to download just the latest value for a time-series?
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 here.
If you are using a time-series dataset and want the latest value from an individual time-series, use the limit=n parameter to get only the most recent n rows of data.
For example, if you are using the NASDAQ Stock Market Prices ( XNAS) data feed and want the latest value for the ACIW time-series, you can use an API call like this:
https://data.nasdaq.com/api/v3/datasets/XNAS/ACIW.csv?limit=1&api_key=YOURAPIKEY
In the above API call, data from the XNAS/ACIW time-series will be returned and only the latest 1 row of data will be returned because limit=1.
To see other parameters for individual time-series, please see the documentation here.
