  First-party client libraries published by VigLink (Sovrn Commerce). Sovrn ships no
  packages to any public language registry — npm, PyPI, RubyGems, Packagist, Maven
  Central, NuGet, crates.io and pkg.go.dev were all probed for viglink/sovrn package
  names and every one returned 404. The only first-party client distribution is the
  Commerce JavaScript library (vglnk), served unversioned from the Sovrn CDN and
  installed as a script tag from the publisher's Commerce install page.

    Both orgs exist. The public sovrn org publishes only Prebid.js / prebid-server
    forks and internal tooling (release-to-jira, brickhouse) — advertising-side
    projects, not Commerce API client libraries. The viglink org publishes no public
    repositories.

  official: true
  registry: cdn

  version_note: >-
    Unpinned CDN distribution. The install snippet loads
    https://cdn.viglink.com/api/vglnk.js with no version segment and the file carries
    no registry metadata endpoint, so a consumer cannot tell which build they are
    executing — it floats to whatever Sovrn last deployed. Probed 2026-08-13:

  api:

  - vglnk.link( link )
  note: >-
    Auto-monetizes outbound links on a publisher page and exposes a small JS API for
    programmatic link monetization. Calls the Link Check API at api.viglink.com/api;
    the api_url option exists so publishers can front it with their own CNAME.

- language: javascript
  name: Automated Comparisons library
  official: true
  registry: cdn
  url: null
  version: null
  published: null
  version_note: >-
    Documented as an embed library but Sovrn publishes no loader URL, version, or
    registry entry on the public docs page — the snippet is issued per publisher.

  note: Price-comparison embed library, distributed as a per-publisher snippet.

  No server-side SDK exists in any language. Every Commerce API is called directly
  over HTTPS with a site Secret Key in the Authorization header.
