Gated on the trading entitlement, like the runs route beside it. Each hour carries, per tier, the scored slot count and the sums of absolute and signed error, so the client can fold hours into days or a time-of-day profile and read MAE and bias off any bucket exactly. Only completed local days are scored, each morning, so the newest hours of the window carry no entry yet. ## OpenAPI ````yaml https://app.podero.com/api/partners/v2.0/openapi.json get /api/partners/v2.0/org/{org_id}/devices/{inverter_id}/forecast-accuracy openapi: 3.1.0 info: title: Podero Partner API version: '2.0' description: >- This API provides a unified interaction point for Podero's partner companies. The goal of this API is to give partners easily integratable endpoints that don't require extensive software development. For this reason, the endpoints focus around user and device management, setting of preferences and high level device controls. While direct control of devices is implemented for special use cases such as pause power, we abstract away low level direct device steering so developers and partners can focus on delivering maximum value to end users. termsOfService: https://www.podero.com/terms-and-conditions servers: [] security: [] paths: /api/partners/v2.0/org/{org_id}/devices/{inverter_id}/forecast-accuracy: get: tags: - Devices summary: Scored forecast accuracy for an inverter, by hour and forecast tier description: >- The scored accuracy of one inverter's forecasts over the last ``days``, per hour and tier.
