  Public package-registry metadata endpoints (registry.npmjs.org, rubygems.org/api,
  pypi.org/pypi, search.maven.org, api.nuget.org), read unauthenticated on 2026-08-14.

  Eligible ships first-party client libraries in five languages. Ownership is
  first-party on every entry: the RubyGems owners are @eligible.com staff handles,
  the npm maintainers all carry @eligible.com addresses, the NuGet author string is
  "Eligible Inc", and the Maven groupId is com.eligible. The GitHub repositories the
  packages point at (github.com/eligible/*, github.com/EligibleAPI/eligible-python)
  are no longer public — only github.com/EligibleAPI/eligible-ruby survives, and it
  is a placeholder that says the official client "has moved". The registries are
  therefore the only readable distribution surface, which is why version/published
  are recorded from registry metadata rather than from a repo.

    note: >-
      The most actively maintained client. 71 published versions; a 3.1.0.beta6
      prerelease shipped the same day as 3.0.3. The gem's own CHANGELOG shows the
      release cadence is dominated by one recurring task — "Updated pinned GDS SSL
      certificate" — because the library pins SHA-1 fingerprints for
      gds.eligibleapi.com and must ship a new version whenever that certificate
      rotates.
  - language: javascript
    registry: npm

    note: >-
      17 versions, first published 2016-02-06. Maintainer accounts are all
      @eligible.com addresses. The published README states the library implements
      only part of the API surface (cost estimation and the coverage/claims/payer
      models present in lib/models), not the full REST surface the Ruby gem covers.
      Do not confuse with the unrelated npm package "eligible", which is a
      create-next-app scaffold by a third party, or "eligible-api", a third-party
      implementation by bookmd.

    note: >-
      Released on the same annual January cadence as the other clients, one cycle
      behind them as of this probe (Ruby, Node and .NET all shipped again in
      January 2026; Java did not).

    note: >-
      ABANDONED. Seven releases, all in 2013; nothing published in the twelve years
      since, against an API whose other clients were re-released in January 2026.
      Eligible's own published Technical FAQ acknowledged the gap as far back as
      2016 ("We do have an older Python library, however we are producing a new
      Python library for release in 2016") and no replacement was ever published to
      PyPI. The linked GitHub repository is gone.
