OpenAPI Specification

info:
  title: Grid Status API Info Reports API
  description: The Grid Status hosted API provides programmatic access to United States and Canadian electricity grid and power market data across CAISO, ERCOT, IESO, ISONE, MISO, NYISO, PJM, and SPP. Data is organized as datasets - day-ahead and real-time LMP and settlement point prices, load and load forecasts, fuel mix, ancillary services, storage, and transmission constraints - that are listed, described, and queried through a uniform interface with time-range filters, column filters, resampling, pagination, and JSON or CSV output. Authenticate with an API key from the Grid Status settings page, passed in the x-api-key header (or api_key query parameter). Grounded in the live OpenAPI 3.1 document published at https://api.gridstatus.io/openapi.json (version 1.3.0).
