  Smart Pension publishes NO first-party client libraries for the Keystone API, in any language.
  This is a deliberate-looking gap rather than an oversight in our search: the developer portal's
  Getting Started, Flows and Client Credentials guides walk the reader through raw curl and
  hand-rolled OAuth, and never mention an SDK; the spec's only x-samples-languages value is
  "curl"; and the public GitHub organisation contains 28 repositories of which none is a Keystone
  client — they are internal tooling, Heroku buildpacks, GitHub Actions and forks, and 22 of the 28
  are archived. The one suggestively-named repo, smartpension/documentation ("Swagger file
  describing Smartpension API"), is archived.
  The integration burden therefore falls entirely on the payroll and benefits vendors listed on
  smartpension.co.uk/payroll-integration, each of whom has written its own client.
