Nasdaq Data Link
Marketplace and API for financial, economic and alternative datasets, formerly known as Quandl, now owned by Nasdaq.
Nasdaq Data Link (the rebranded Quandl, acquired by Nasdaq in 2018) is a marketplace for financial, economic and alternative datasets — pricing, fundamentals, macroeconomic indicators, and niche alternative-data feeds like satellite or transaction data — delivered through a single, consistent API and downloadable file formats. Each dataset is published by an individual provider (some free, most paid or subscription), so coverage, refresh frequency and licensing vary by listing even though access goes through one uniform API. It suits quant researchers, analysts and fintech teams who want programmatic access to many financial datasets without integrating a different API per provider, more than teams wanting to publish their own data widely.
