NuGet Search API

The NuGet Search API allows clients to query for packages available on a NuGet package source using the SearchQueryService resource found in the service index. It supports filtering by keyword, target framework, prerelease status, and package type, and returns paginated results with package metadata including versions, descriptions, download counts, and dependency information.

NuGet Search API is one of 7 APIs that NuGet publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
