description: >-
  NESO publishes NO first-party client library on any package registry. The
  neso-energy GitHub organisation exists but is empty; the carbon-intensity
  organisation - whose api-definitions repository is described by NESO as "the
  Official Carbon Intensity API for Great Britain, developed by NESO" - carries
  documentation, methodology, terms and two demo applications, but no SDK. Every
  package listed below is third-party and is recorded as official:false. No SDKs
  pointer is wired in apis.yml because no first-party SDK exists.
