Octopus Energy

Octopus Energy is a UK-founded retail energy supplier and the parent of Kraken Technologies, the AI-powered energy operating system that runs both Octopus and many of the world's largest utilities. Octopus operates a free, open REST API at api.octopus.energy/v1/ that exposes the full UK product catalog, electricity and gas tariff pricing (including the half-hourly wholesale-linked Agile Octopus and Tracker tariffs), meter-point details, half-hourly smart-meter consumption, and industry grid supply points. The Kraken developer portal at developer.octopus.energy adds a second REST surface generated from an OpenAPI spec plus a GraphQL API at /v1/graphql/ with API Collections grouping partner-facing queries and mutations for accounts, ledgers, billing, smart meters, EV charging, heat pumps, batteries, and Intelligent Octopus dispatch. Through Kraken Technologies the same platform powers 90M+ customer accounts at EDF, E.ON, Origin Energy, Tokyo Gas, Plentitude, National Grid, Severn Trent, and other utilities in 30 countries — making Octopus one of the most consequential open and programmable surfaces in retail energy.

Octopus Energy publishes 7 APIs on the APIs.io network, including Consumption API, ElectricityMeterPoints API, ElectricityTariffs API, and 4 more. Tagged areas include Energy, Electricity, Gas, Renewable Energy, and Smart Meter.

The Octopus Energy catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Octopus Energy’s developer surface includes authentication, developer portal, documentation, changelog, signup flow, support, engineering blog, and 41 more developer resources.
