    OVO Energy publishes NO client SDK for an OVO Energy API, because it publishes
    no API. What OVO Technology does publish, and publishes prolifically, is
    general-purpose internal engineering tooling — Scala (Maven Central, groupId
    com.ovoenergy), TypeScript/Node (npm, scope @ovotech) and Go (pkg.go.dev,
    github.com/ovotech). Those are first-party OVO packages but they are NOT API
    client libraries: none of them talks to an OVO Energy product API. The only
    package that does reach OVO customer data is a COMMUNITY Python client built
    on the undocumented customer-session endpoints, and its own README says it is
    not officially supported. Nothing here earns an SDKs pointer.
packages:
  # ---- community API client (NOT first party) ----
  - language: python
    registry: pypi
    name: ovoenergy
    version: 3.0.2

      Community OVO Energy Python client — the library behind the Home Assistant
      OVO Energy integration. Talks to the undocumented customer-session endpoints
      (the same surface as smartpaymapi.ovoenergy.com), not to a published API.
      Its own README states: "This package is not officially supported by OVO
      Energy and is provided as-is. If OVO change their APIs, this package may
      break." Recorded as evidence of demand, not as an SDK.
  # ---- first-party OVO Technology open-source libraries (NOT API clients) ----
  - language: scala
    registry: maven
    name: com.ovoenergy:natchez-extras-core
    version: 8.1.1

    note: >-
      Distributed-tracing integrations (Datadog, http4s, doobie, fs2, log4cats)
      for the Natchez Scala library. 66 artefacts published under groupId
      com.ovoenergy on Maven Central for Scala 2.13 and 3. Internal engineering
      tooling — no OVO Energy product API is involved.
  - language: typescript

      "A minimal nodejs http server, built around the concept of strictly typed
      middlewares" — an OpenAPI-first HTTP server framework OVO uses to BUILD
      services, plus @ovotech/laminar-cli which generates TypeScript types from an
      OpenAPI document. Notable in context: OVO ships OpenAPI-driven tooling to
      the world while publishing no OpenAPI of its own.
  - language: typescript
    registry: npm

    note: >-
      Converts Avro schemas into TypeScript interfaces; part of a family with
      @ovotech/avro-kafkajs, @ovotech/avro-mock-generator, @ovotech/blaise and
      @ovotech/castle (Kafka consumer framework). Evidence of a real internal
      event-driven/Kafka estate — none of which is externally documented, and none
      of which yields a public AsyncAPI.

      Rotates cloud provider access keys; one of OVO Technology's better-known
      Go tools alongside github.com/ovotech/gitoops (Neo4j-based CI/CD attack-path
      mapping). Security/platform tooling, not a product API client.
