EDF Kraken GraphQL API is one of 3 APIs that [EDF Energy](https://apis.io/providers/edf-energy/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include GraphQL, Kraken, Tariffs, Energy Products, and Smart Metering. The published artifact set on APIs.io includes API documentation, an API reference, a changelog, authentication docs, and rate-limit docs.

EDF Energy's primary developer API, and the surface EDF markets as its "open tariff APIs". It is the Kraken GraphQL API, licensed from Octopus Energy Group and hosted for EDF GB. Introspection is enabled anonymously: a standard IntrospectionQuery POSTed with no credentials returned HTTP 200 on 2026-07-27, yielding 2,492 types, 246 Query fields and 417 Mutation fields, saved verbatim as SDL in this repository. Retail product and tariff data resolves without any credential — energyProducts(postcode: "SW1A1AA", brand: "EDF") returned live EDF tariffs including EDF_FOL_06M_B1_1YR_26-07-24_v1 "Fixed Online 1 Year". Everything customer-scoped (smartMeterTelemetry, annualElectricityConsumption, applicableRates, plannedDispatches, vehicleChargingPreferences, fitInstallations, prepay ledgers) requires an Authorization header held by the account user, an organisation, or an OAuth application. Published limits: 50,000 points/hour for account users, 100,000 for organisations, 300,000 for OAuth applications; complexity limit 200; 10,000 nodes per request; rate-limit error KT-CT-1199. No consumer data mandate in Great Britain produced any of this.
