John Deere has a developer API for their Operations Center (field data, equipment telemetry, machine locations, etc.) but no official SDK. I needed it for a project, so I built one and open-sourced it.

28 APIs, 123 operations, fully typed, auto-pagination, HAL support, automatic retries. Generated from their OpenAPI specs with daily health checks.
