  xCures ships NO first-party client library in any public package registry. Every registry was queried
  unauthenticated on 2026-09-04 and every one came back empty: npm search "xcures" total 0,
  pypi.org/pypi/xcures/json 404, rubygems.org/api/v1/gems/xcures.json 404, crates.io search total 0,
  packagist search empty, no Maven/NuGet coordinate. The company's GitHub organization
  (https://github.com/xCures, created 2019-11-01) is public but holds only two research repositories —
  dateparser_with_bounds (Python) and keras_lstm_vae (Jupyter) — neither of which is an API client.
  This matters because the surface LOOKS like it has SDKs: the docs footer carries an "SDKs" link, the
  changelog page is titled "Release notes and changes for the xCures API and client SDKs", and the
  Postman collection is named "xCures SDK — Workflow Playbook". What xCures calls its SDK is a
  documentation and Postman surface, not a distributed library.

    note: >-
      The docs footer "SDKs" link 302s to the Redocly portal login. So does /faq and
      /platform_user_guide. If a distributable client library exists it is behind that customer login and
      is not publicly enumerable; nothing is asserted about it here.
distributed_artifacts:
  note: >-
    These are the things a developer actually downloads from xCures today. Neither is a versioned package
    and neither has a registry metadata endpoint, so version and published are recorded null with the
    reason.
  artifacts:
    - name: xCures SDK — Workflow Playbook (Postman collection)
      registry: direct-download
      url: https://docs.xcures.com/downloads/xCures_SDK_Workflows.postman_collection.json
      http_status: 200
      official: true
      version: null
      published: null
      version_note: >-
        Checked, nothing to record. The file carries an internal _postman_id of
        "xcures-sdk-workflows-v1" but no semantic version, no dated release and no registry entry, and
        the download URL is unpinned — it floats to whatever is current, so a consumer cannot tell what
        they are getting either.
      contents: 75+ requests across 11 workflow folders
      file: ../examples/xcures-workflow-playbook.postman_collection.json
    - name: xCures Agent Skills
      registry: direct-download

      version: null
      published: '2026-08-19'
      version_note: >-
        No version field on the skills or the index. Each entry does carry a sha256 digest, which pins
        content without naming a version; the publication date is taken from the changelog entry that
        announced them.
      contents: 6 SKILL.md documents
      file: ../skills/_index.yml
third_party:
  note: NOT official. Recorded only so it is not mistaken for a first-party SDK on a later pass.
