What is Nasdaq Data Link's nomenclature system for data? What are Time-Series, Tables and Product Codes?
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.
Each time-series or tables data feed on Nasdaq Data Link has a short (3-to-6 character) ID known as "product codes" (formerly Quandl codes).
You will need to use these product codes when using the REST API for time-series or tables.
- The Berlin Stock Exchange Prices data feed has product code XBER. The product page for this data feed is at https://data.nasdaq.com/data/XBER-berlin-stock-exchange-prices - note that the URL contains the product code XBER. Note also the right panel of the product page which indicates that this data feed is to be used with the "time-series API" (REST API for time-series).
- The Core US Fundamentals data feed has product code SF1. The product page for this data feed is at https://data.nasdaq.com/databases/SF1/data - note that the URL contains the product code SF1. Note also the right panel of the product page which indicates that this data feed is to be used with the "tables API" (REST API for tables).
See our complete API documentation here.
Time-series data feeds, such as Berlin Stock Exchange Prices, contain many individual time-series which have their own codes appended to the parent product code, like this:
Royal BAM Group NV (BGPA) Adjusted Stock Prices: XBER/BGPA
For instructions on how to download product codes for every single time-series in a time-series data feed, please see here.
Tables data feeds, such as Core US Fundamentals ( SF1) contain one or more tables which have their own table codes.
Core US Fundamentals is a collection of tables and the product code for each individual table is shown on the Core US Fundamentals product page here. The product code for the Core US Fundamentals table is SHARADAR/SF1, the product code for the Tickers and Metadata table is SHARADAR/TICKERS, the product code for the Indicator Descriptions table is SHARADAR/INDICATORS and so on.
