  NuGet is the package manager for .NET, providing a centralized repository for
  developers to discover, share, and consume reusable code libraries. The NuGet
  developer platform exposes a set of HTTP APIs that enable programmatic access
  to package search, metadata retrieval, content download, catalog browsing,
  and package publishing against the nuget.org feed.

    description: >-
      The NuGet Server API is a set of HTTP endpoints used to download
      packages, fetch metadata, publish new packages, and perform other
      operations against a NuGet package source. The V3 API uses JSON as its
      underlying media type and is accessed through a service index located at
      https://api.nuget.org/v3/index.json, which enumerates all available
      resources and capabilities.

    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, and deleted. 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.

    description: >-
      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.

    description: >-
      The NuGet Package Metadata API, accessed through the RegistrationsBaseUrl
      resource, provides detailed metadata about packages available on a NuGet
      package source. It returns registration information including all
      available versions of a package, their dependencies, download URLs,
      descriptions, authors, license information, and deprecation status.

    description: >-
      The NuGet Package Content API, accessed through the PackageBaseAddress
      resource, allows clients to download package content files (.nupkg) and
      package manifests (.nuspec) from a NuGet feed. It uses a flat container
      structure where packages are organized by lowercase package ID and
      version, providing direct access to the binary package files.
