  The FCA publishes NO first-party SDK or client library in any language. Every
  package below is community maintained and is recorded here only so the
  ecosystem around the Financial Services Register API is visible; none of them
  is official, so no `SDKs` pointer is wired in apis.yml. Registries probed with
  no first-party result: npm, PyPI, Maven Central, NuGet, pkg.go.dev, RubyGems,
  Packagist, crates.io. No official FCA GitHub organisation exists (api.github.com
  /orgs/FCA-UK and /orgs/financial-conduct-authority both 404).
