Endpoint

GET https://api.datafornerds.io/v2/microsoft/windows-server-update-history.json

A filtered subset of the full Windows Update History containing only Windows Server records (OSType = "Server").

Same 10-field schema as the full dataset. All records have OSType = "Server".

Field	Type	Description	Example
`OSType`	string	Always "Server" in this dataset	`Server`
`MajorVersion`	integer	Server product year (e.g. 2022, 2025)	`2022`
`WindowsVersion`	string	"2022", "23H2", "2025", etc.	`2022`
`KBNumber`	string	Knowledge Base article number	`KB5058385`
`OSBuild`	string	Full OS build number	`20348.5139`
`FullVersion`	string	NT version string	`10.0.20348.5139`

`IsExpired`	boolean	Whether Microsoft has marked this update as expired	`false`
`ArticleUrl`	string	URL to the KB article	`https://support.microsoft.com/kb/5058385`

Notes

Only Windows Server 2022 and Windows Server 2025 are currently supported. Older server versions (2019, 2016, etc.) are not included.
Microsoft marks EXPIRED inconsistently across version sections on their update history pages. DataForNerds normalizes this at the KB level: if any version of a KB is marked expired, all versions of that KB are reported as expired.
