  summary: Anonymous, key-free HTTP downloads of the Ontario Energy Board's published open datasets.
  description: 'A machine-readable description of the Ontario Energy Board''s Open Data programme as an HTTP surface.


    PROVENANCE. The OEB publishes no OpenAPI, no API reference and no base path. Open Data is a set of stable, versioned files linked from 40 dataset landing pages under https://www.oeb.ca/ontarios-energy-sector/open-data. This document was GENERATED by API Evangelist on 2026-07-27 by crawling those pages and probing the files they link. Only files that returned HTTP 200 to an anonymous request in that run appear as operations, and each carries an x-evidence block with the probed URL, status, content type, byte size and Last-Modified. The OEB''s pages link a further ~165 historical and current RRR files (the 2015-2021, 2023 and 2024-2 series, plus the natural gas GD series) that this run could not verify because the host stopped answering under sustained probing; the full published inventory is recorded in data-model/ontario-energy-board-data-model.yml rather than asserted here as live operations.


    There is no query interface: no parameters, no pagination, no filtering, no content negotiation, no conditional request contract beyond the Last-Modified/ETag the web server sets. Every operation is an unconditional GET of a whole file. Authentication: none.


    Rate limiting: undocumented but real. Sustained parallel requests from one client caused www.oeb.ca to stop answering entirely (connection timeouts, no HTTP status) on 2026-07-27. Fetch serially and cache.'
