  title: API Evangelist enhancements for OEB Regulatory Document Search
  version: 1.0.0
extends: openapi/ontario-energy-board-rds-openapi.yml
x-generated: '2026-07-27'
x-method: generated
x-source: >-
  Live anonymous probes of https://www.rds.oeb.ca/CMWebDrawer on 2026-07-27 plus the live search-clause
  vocabulary at /Help/WDSearchClauseDefJS
x-note: >-
  The base document is itself generated by API Evangelist, because the Ontario Energy Board publishes no
  specification for this surface. This overlay records the enhancements that are OUR editorial layer
  rather than observed protocol facts - provenance flags, the pointer to the derived query vocabulary,
  the read-only/agent-safety annotations and the error-handling warnings an agent must carry. Keeping
  them in an overlay means the generated base can be regenerated from probes without losing them.

        HTTP 200 does not mean the query succeeded. Read SearchTitle on every response - an unknown
        clause or a wildcard used with '=' returns 200 with an empty Results array and the reason in
        that field.

        Take metadata from the search hit and fetch bytes from /Record/{uri}/File/document; record
        detail returns HTTP 500 TrimException (TrimErrorCode 22760) to anonymous callers.

        Check RecordExtension on the search hit before assuming PDF; correspondence is frequently MSG.
