  label: NuGet Catalog API
  description: The NuGet Catalog API is an append-only resource that records the full history of all package events on nuget.org,
    including packages being added, modified, listed, unlisted, deleted, deprecated, and having vulnerability status updated.
    It provides a chronologically ordered log of every change to the package source, enabling consumers to build and maintain
    their own local copy of the entire set of packages available on nuget.org. The catalog is indexed by time and uses a hierarchical
    structure of index, pages, and leaves. Not all package sources implement the catalog resource.
