PJM Data Miner 2 API

aid: pjm:pjm-data-miner-2-api
name: PJM Data Miner 2 API
description: PJM's public wholesale market and system data catalogue, exposed as a REST API behind Azure
  API Management. Feeds include day-ahead and real-time hourly and five-minute LMPs, ancillary service
  prices and market results, generation by fuel type, hourly metered/estimated/preliminary load, load
  forecasts, generation and transmission outages, FTR auction bids and zonal LMPs, pnode and aggregate
  definitions, and uplift and billing determinants. Each feed supports a /metadata call and a search call
  with rowCount/startRow paging, field selection, sorting and date-range filters, and JSON or CSV output.
  The data is designated public by PJM and the key is free, but anonymous calls are rejected — verified
  HTTP 401 on GET https://api.pjm.com/api/v1/gen_by_fuel on 2026-07-27 — and redistribution requires at
  minimum a PJM Associate Membership.
