  Registry searches on 2026-09-05 — registry.npmjs.org search for "clearstream", pypi.org/pypi
  for clearstream / clearstream-api / clearstream-sdk (all 404) — plus a read of the Clearstream
  API Developer Guide (August 2025) and the Clearstream API services page.
description: >-
  Clearstream publishes no first-party client libraries. The only integration example Clearstream
  ships is a bash/curl script printed in the API Developer Guide; the guide's own framing is that
  clients build against HTTP directly, using standard mutual-TLS-capable HTTP tooling. Nothing on
  npm, PyPI, Maven Central, NuGet, RubyGems, crates.io, Packagist or pkg.go.dev is published by
  Clearstream Banking S.A.

      No package published by Clearstream Banking. The nearest hit, @churchapps/texting
      (version 0.4.0, published 2026-08-18), belongs to an unrelated US church SMS product also
      called Clearstream (clearstream.io) and is explicitly NOT attributed here.

  "Clearstream" is also the name of a US church text-messaging company at clearstream.io, which
  owns the GitHub organisation github.com/clearstream (repos: sms-calculator, xml-to-array,
  code-challenge; org bio "Clearstream is the church texting (and email!) service you'll love").
  That organisation has no connection to Clearstream Banking S.A. and must not be attributed to
  this record. It was previously wired into this repo's apis.yml as a GitHubOrganization pointer
  and was removed on 2026-09-05.

    Requests an access token with --cert / --cacert against /authmanager/oauth2/access_token,
    parses it with jq, then calls /playground/v1/echo. Dependencies named: a recent curl (the
    guide states 7.47.0 does not work) and jq.
