PJM Data Miner 2 API is one of 6 APIs that [PJM Interconnection](https://apis.io/providers/pjm/) publishes on the [APIs.io](https://apis.io/) network.

The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, a changelog, and rate-limit docs.

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.
