  Versions and publish dates are read from the registry metadata endpoints at
  fetch time, not from prose.

  RB2B ships no conventional server-side SDK in any language. Its first-party
  distributable code is (a) an MCP server on npm that wraps the Identity /
  Enrichment API, (b) a WordPress plugin distributed from GitHub, and (c) the
  browser tracking pixel distributed from CloudFront. PyPI, RubyGems, Packagist,
  crates.io, NuGet, Maven Central and pkg.go.dev return no RB2B package. There
  is no rb2b GitHub organisation — https://api.github.com/orgs/rb2b returns 404.

    note: >-
      The only registry-published RB2B client library. Published under the @rb2b
      npm scope, package author "RB2B". Wraps the 13 REST endpoints of
      https://api.rb2b.com/api/v1 as 19 MCP tools; ships a bin,
      `rb2b-apis-mcp`. The named git repository is not publicly readable
      (GitHub API 404) — the npm tarball is the readable artifact.

      Injects the RB2B tracking snippet into the WordPress global header; the
      user pastes their RB2B Account ID from
      https://app.rb2b.com/script/setup_script_html. Distributed from a GitHub
      repository, not the WordPress.org plugin directory, so there is no
      registry metadata endpoint and no released version to read — version and
      published are null because there is nothing published to record, not
      because they were not checked. RB2B's changelog dates a plugin update to
      2026-05-13 ("updated to ensure that it works with the latest version of
      WordPress").

    kind: browser-pixel
    note: >-
      Per-account build served from CloudFront; the URL embeds the account ID,
      not a version, so it floats to whatever RB2B currently serves and a
      consumer cannot tell what they are getting. There is no CDN JSON metadata
      endpoint for this path. The only version marker RB2B exposes is an
      in-snippet constant, `reb2b.SNIPPET_VERSION = "1.0.1"`, documented in the
      framework install guides — recorded here as a note rather than as
      `version:` because it labels the loader snippet, not the fetched bundle.

      Third-party n8n community node that receives RB2B visitor webhooks. Listed
      for completeness and explicitly NOT counted as a first-party SDK. RB2B
      does document an official n8n integration on its own side
      (support.rb2b.com/en/articles/11838541-setup-guide-n8n).

  server_side_sdk_note: >-
    No first-party REST client library exists for any server-side language. An
    integrator calls https://api.rb2b.com/api/v1 with a plain HTTPS request and
    an Api-Key header, or drives it through the MCP server.
