description: Elexon is the UK's Balancing and Settlement Code (BSC) Company, responsible for administering the electricity
  balancing and settlement arrangements in Great Britain. As the operator of the Balancing Mechanism Reporting Service (BMRS),
  Elexon publishes a publicly accessible REST API — the Insights Solution API — that provides free, no-key access to real-time
  and historical data from the UK electricity market. The API covers balancing mechanism dynamic and physical data per Balancing
  Mechanism Unit (BMU), bid-offer acceptances, balancing services adjustments, physical notifications, generation availability
  forecasts, settlement reports, meter readings, and UK market transparency data mandated under European legislation. All
  data is returned in JSON, XML, or CSV format. A companion near-real-time push service (IRIS — Insights Real-time Information
  Service) streams the same datasets over WebSocket/STOMP for latency-sensitive consumers. The API is freely accessible to
  industry participants and the public with no registration or API key required, and data may be reused with attribution ("Contains
  BMRS data © Elexon Limited copyright and database right").

  description: The Elexon Insights Solution API is a publicly accessible REST API providing free access to UK electricity
    balancing and settlement data. The API requires no authentication or API key and serves production-grade data continuously.
    Endpoints are grouped into Dataset Endpoints (raw published data, including superseded historical records), Opinionated
    Endpoints (specific use-case queries such as demand evolution or generation availability), Streaming Endpoints (JSON only,
    no paging restrictions), and Summary/Reference Data endpoints. Response formats include JSON, XML, and CSV. Core data
    domains include balancing mechanism dynamic and physical data per BMU, bid-offer data and acceptances, disaggregated and
    net balancing services adjustments (DISBSAD/NETBSAD), physical notifications (PN/QPN), non-BM STOR (NONBM), and 50+ BMRS
    datasets covering generation, demand, frequency, temperature, and market transparency. An interactive OpenAPI specification
    is published at https://data.elexon.co.uk/swagger/v1/swagger.json.
