What it does
Nasdaq Data Link brings financial datasets into a searchable catalogue with programming interfaces and integrations for Python, R and Excel. Its product range includes company fundamentals, fund information, index data and market prices. Analysts and developers can choose a data product around the figures and delivery method their project needs.
Nasdaq Data Link is useful when a spreadsheet or application needs a repeatable source of financial data. Its catalogue includes Sharadar company fundamentals and holdings, Nasdaq Fund Network information and index feeds. These products share a distribution platform, but their coverage and definitions are different.
For a price display, the API overview distinguishes Last Sale, which follows the market's qualifying-sale rules, from Last Trade, which reflects the latest transaction. Last Quote supplies the best bid and offer, while Snapshot combines daily price fields. Historical Bars can be requested by date or date range and interval. That distinction matters when deciding what a chart, quote tile or calculation should represent.
Start with the dataset that matches the market and fields you need, then choose an integration. Nasdaq provides routes for Python, R and Excel as well as application programming interfaces (APIs). Review the chosen product's coverage, permitted use and access terms before building it into a recurring report.
