Nasdaq Data Link

About Nasdaq Data Link

Nasdaq Data Link provides financial and economic data through APIs, along with SDKs and tools for accessing that data. It offers a core API, a streaming API for real-time or delayed data, and a table API, alongside SDKs for Python and R and an Excel add-in for importing data directly into spreadsheets. SQL-based access is also documented, with installation and authentication guides provided for each method.

The documentation is aimed at developers and analysts who need to search for, extract, and analyze financial/economic data at varying levels of technical expertise, from spreadsheet users to programmatic API consumers. Guides cover installation, authentication, and usage for each supported tool (API, Python, R, Excel, SQL), including separate documentation for a Windows-based Pro client and a web-based version.
