  title: GridX Enterprise Rate Platform Authentication Customer API
  description: Partner/enterprise API for the GridX Enterprise Rate Platform. The documented surface (the "Calculate" / pricing-engine APIs) covers dynamic pricing retrieval, customer account info and interval usage, and OpenADR demand-response program subscriptions. Documentation is published per utility deployment; the canonical reference is the PG&E deployment hosted at pge-pe-api.gridx.com, with an equivalent SCE pricing endpoint. Endpoint paths and shapes below reflect the public GridX Calculate API documentation; request and response schemas are summarized and may vary by utility deployment and by the GridX Empower (rate/bill/cost analysis) product contract, which is not fully published. No undocumented endpoints are fabricated here.
