OEB Regulatory Document Search (RDS) is one of 2 APIs that [Ontario Energy Board](https://apis.io/providers/ontario-energy-board/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 1 JSON Schema definition. Tagged areas include Regulatory, Document Search, Filings, Decisions, and Licences. The published artifact set on APIs.io includes API documentation, an API reference, an OpenAPI specification, authentication docs, and 1 JSON Schema.

The OEB's public regulatory document search, serving every filing, decision, order, licence, code amendment and piece of correspondence in the Board's case record. It runs on Micro Focus / OpenText Content Manager WebDrawer, and the OEB links directly to parameterised query URLs of the form /CMWebDrawer/Record?q=CaseNumber=EB-2021-0183&sortBy=recRegisteredOn-&pageSize=400 from its own website — the licensed-companies list alone links hundreds of them. Fetched anonymously on 2026-07-27, this surface also honours a `format=json` parameter and returns application/json — a Content Manager ServiceAPIModel payload with Results, TotalResults, Count, HasMoreItems and typed Fields including CaseNumber, SIDocumentType, Applicant, EnergyType, PrimaryApplicationType and DateIssued — while /CMWebDrawer/Record/{uri}/File/document returns the underlying PDF. IMPORTANT — the OEB publishes no API reference, no base-URI statement, no query-syntax documentation, no OpenAPI and no terms for this interface; the JSON output is default behaviour of the underlying WebDrawer product, not a product the OEB documents or supports. It is recorded here because it was verified live and anonymous, not because it is an offered API. No key, no signup, no rate-limit policy published.
