  title: Itron Starfish Data Platform API
  version: '1.0'
  summary: Device and observation REST API for the Itron Networked Solutions (Starfish) Data Platform.
  description: |
    Reconstructed OpenAPI specification for the Itron / Itron Networked Solutions
    (formerly Silver Spring Networks) Starfish Data Platform, based on the public
    `starfish-js` SDK (https://github.com/silverspringnetworks/starfish-js) and the
    Silver Spring Networks API Overview (https://developer.ssni.com/api-overview).

    The Starfish Data Platform exposes three primary resources:

    - **Devices** — IoT/sensor devices registered against a solution.
    - **Observations** — Time-series sensor data emitted by those devices.
    - **Device Templates** — Reusable shapes that describe a device's sensors.

    Authentication uses OAuth 2.0 client-credentials (a long-lived `clientId` and
    `clientSecret`) for backend integrations, or a short-lived bearer token issued
    by the Tokens API for browser-side use.

    NOTE: This spec is a best-effort reconstruction for catalog purposes; the
    authoritative reference remains the gated Itron developer portal.
