A time-series is a collection of observations or measurements taken over a period of time, generally in equal intervals. Time-series only contain numeric data types and are indexed by one date field. In other words, time-series data are always sortable by date. Through our API calls, users can retrieve the entire time-series or any slice of it.
Many of Nasdaq Data Link’s databases are stored as time-series because financial data generally consists of two types: dates and observations, which perfectly fit the time-series format.
The time-series API gives you a choice of three formats (JSON/XML/CSV) and libraries for multiple tools.
You do not need any special software to use the Nasdaq Data Link API for Time-Series. All calls are made directly in your browser's address bar. You can also make API calls from your computer's command line (console/terminal), using curl, wget or similar utilities.
