Nasdaq Data Link

Nasdaq Data Link is the financial, economic and alternative-data platform of Nasdaq, Inc., operated at data.nasdaq.com. It aggregates and distributes numerical datasets from hundreds of publishers through a unified subscription interface and API^[1].

The platform positions itself as a one-stop source for finding and consuming data, offering millions of financial and economic datasets delivered through REST APIs, streaming feeds and client tools for Python, R, Excel and SQL^[2].

What It Does

Nasdaq Data Link acts as both a marketplace and delivery infrastructure for third-party data. Publishers list datasets on the platform, while subscribers access them through standardized APIs and tooling rather than negotiating separate integrations with each provider^[1][2].

Content spans traditional financial and economic series as well as alternative data, organized as classic time-series "datasets" and more complex relational "tables"^[1][2].

Products and Delivery

Documented delivery channels include a REST API for tables, a streaming API, and an API for real-time or delayed data. Client tooling comprises a Python SDK and command-line interface, an R package, an Excel add-in (including a NASDAQ.TABLE worksheet formula) and SQL clients for querying tables data^[2].

The platform enforces authentication and rate limits on API usage, and documents enterprise firewall workarounds such as IP whitelisting for institutional deployments^[2].

Buyers and Use Cases

Typical users are quantitative analysts, developers and researchers who pull published datasets directly into Python, R or Excel workflows; documentation emphasizes extracting millions of datasets from hundreds of publishers into those environments with minimal setup^[2].

Landscape

Nasdaq Data Link sits within Nasdaq, Inc.'s broader data and analytics business. The exchange operator combined its global data products and index businesses into a Global Information Services unit in 2013 and generates revenue from market data among other services^[3].

As an aggregator, it competes with other data marketplaces and direct-from-provider licensing models in the alternative-data industry, offering smaller publishers distribution reach while giving subscribers uniform API access^[1].
