  Elexon's Insights Solution API is provided free of charge to the public and industry

  data under the Balancing and Settlement Code (BSC). All data interfaces are freely
  accessible with no subscription, no API key, and no registration required. There are
  no paid tiers. Data may be reused with attribution under the BMRS Data Licence.
  The companion IRIS (Insights Real-time Information Service) push service is also
  free and public.
