MISO Market Reports

name: MISO Market Reports
description: 'MISO''s long-running bulk market report surface — the second fully anonymous layer of its
  open market data, and the archive the Data Exchange APIs sit on top of. Every published report is a
  plain HTTP GET against docs.misoenergy.org/marketreports/ with no key, no account, no login and no licence
  click-through, returning real CSV, XLSX, XML, ZIP and PDF files named by market date. Confirmed anonymous
  on 2026-07-27: 20260726_da_expost_lmp.csv returned HTTP 200 with 1,165,710 bytes of day-ahead ex-post
  LMP, 20260726_sr_gfm.xlsx returned HTTP 200 with 21,922 bytes, and Dead_Node_Reports_Readers_Guide.pdf
  returned HTTP 200. The report catalogue is browsed from the Market Reports page, which drives an internal
  Episerver Find search service — there is no documented query API, no directory listing (docs.misoenergy.org/marketreports/
  itself returns HTTP 404) and no specification, so this is recorded as a verified public data surface
  rather than a specified API.'
