  title: Octopus Energy Public Consumption API
  version: '1.0'
  description: 'The Octopus Energy Public API is a free JSON-over-HTTPS REST API exposing the

    UK product catalog, electricity and gas tariffs, electricity and gas meter

    points, half-hourly smart-meter consumption, and industry grid supply points.


    Authentication uses HTTP Basic auth with a per-customer API key as the

    username and an empty password. Products and tariffs endpoints are open and

    do not require authentication; meter-point and consumption endpoints require

    a key for the account that owns the meter.
