  registry queries against npm, PyPI, Packagist, RubyGems, crates.io and the
  WordPress.org plugin API, plus the DeBounce GitHub organization
  (https://github.com/debounceio) and the integrations pages on debounce.com
description: >-
  DeBounce publishes NO first-party client SDK library on any language package
  registry. What it does distribute officially is platform plugins and sample
  code: a WordPress plugin on WordPress.org, a Google Sheets add-on on Google
  Workspace Marketplace, an unpinned JavaScript widget loader on its own CDN, and
  a single PHP sample script on GitHub. Integrators call the REST API directly
  with an HTTP client. Because the API is a query-string GET surface with no
  request bodies, the absence of an SDK is a lower cost here than it would be for
  most APIs — but it is still an absence, and it is recorded as one.

  note: >-
    The distribution is UNPINNED — the documented snippet on
    https://debounce.com/solutions/javascript-widget/ loads a bare
    cdn.debounce.io/widget.js with no version segment and no integrity hash, so a
    consumer cannot tell which build they are getting and neither can this probe.
    There is no jsDelivr/unpkg metadata endpoint for a vendor CDN. Recorded as
    null after checking, not as unchecked. Separately, a live GET of that exact
    URL returned HTTP 200 with content-length 0 and content-type image/jpeg on
    2026-08-14, both with and without a browser User-Agent and Referer — the
    documented loader served an empty body at probe time.

  note: >-
    Google Workspace Marketplace exposes no unauthenticated version/date metadata
    endpoint, so version and published date are null after checking. Linked as
    official from the debounce.com footer.

    "PHP Sample code of DeBounce email verification API call." The repository
    contains a README and a single verify.php script — it is example code, not a
    packaged library, and it is not published to Packagist (a
    repo.packagist.org lookup for a debounce vendor returned 404). It is the ONLY
    repository in the debounceio GitHub organization. Recorded as version null
    because there is no registry release to read.
