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].

Questions to ask Nasdaq Data Link

Which publishers control the underlying licenses and redistribution terms for each dataset? How are revisions, symbol changes, schema changes, and discontinued products communicated? What point-in-time history is preserved for backtesting? What API rate limits and service levels apply by subscription tier, and what happens to historical access if a third-party publisher leaves the platform?

Compliance and legal considerations

Licensing varies by publisher and dataset, so subscribers should verify entitlements for storage, redistribution, derived works, and use across teams or applications. Exchange and real-time market data can carry additional display and redistribution restrictions, while third-party datasets remain subject to the originating publisher's terms.
