DataForNerds is a free JSON API designed to collect, merge, and normalize reference data scattered across Microsoft support pages, release notes, and specification documents. It currently covers Windows 10/11/Server update history, Microsoft 365 Apps version history, Office language codes, and mappings from Windows versions to base build numbers. In short, it solves the problem of “stop writing one-off scrapers and maintaining outdated spreadsheets yourself.”
The service provides a unified /v2/ API, with responses using a fixed envelope that includes metadata and data. The metadata includes the dataset name, record count, source URLs, lastModified, lastCollected, and other fields, making auditing and incremental checks easier. Each dataset comes with a JSON Schema, with clear field types and meanings. The API supports GET, HEAD, and OPTIONS, as well as ETag/If-None-Match conditional requests, 304 responses, Cache-Control, Last-Modified, and open CORS, so it can be called directly from browser JavaScript. Examples are provided for PowerShell, Python, JavaScript, C#, curl, and Go, and Power BI usage is also mentioned.
The text clearly labels it as a Free JSON API, with no API key or authentication required. The terms of use allow personal, commercial, and other use cases, provided that the rights of the original content are not infringed. Attribution to DataForNerds is encouraged but not required. Note that this is an unsupported personal project, provided as-is, with no SLA. The official guidance also recommends caching data locally for high-frequency applications.
Its advantages are a very low barrier to use, a stable data structure, solid documentation and code examples, and daily updates via an automated collection pipeline. For tasks such as patch reporting, version compliance checks, and Office language code conversion, it can significantly reduce data-cleaning effort. The downsides are that its current data scope is concentrated on the Microsoft ecosystem; Windows Server coverage only includes 2022 and 2025; and there is no visible information about an official SDK, self-hosting option, enterprise support, or open-source repository. Also note that v1 raw.datafornerds.io will be retired on November 1, 2026.
It is suitable for IT administrators, DevOps teams, data analysts, and developers who need to embed Microsoft update data into their workflows. It is not ideal for enterprise core systems that require a strong SLA, broad software vendor coverage, or private deployment. The text does not provide information about access from mainland China. Since it is hosted on Cloudflare Worker/R2, actual availability should be tested in practice. Payment is not an issue because it is currently free. Alternatives include using Microsoft Learn/Support pages directly, building your own scraper, or evaluating official interfaces such as Microsoft Graph.
