FERC Open Data API is one of 2 APIs that [FERC](https://apis.io/providers/ferc/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Open Data, Energy Markets, Electricity, Natural Gas, and Regulatory Data. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, authentication docs, and rate-limit docs.

FERC's public open data API, serving the same data assets and datasets published in the data.ferc.gov Data Catalog. A Data-Assets endpoint returns the catalog and the dataset IDs; Details, Data, and Dictionary endpoints return per-dataset metadata, full row data, and column definitions. Free self-serve API key, 1,000 requests per hour, X-Api-Key header or api_key query parameter. Runs on the api.data.gov API Umbrella stack (x-api-umbrella-request-id) hosted on cloud.gov. Verified live 2026-07-27 — an unauthenticated GET returns HTTP 403 with API_KEY_MISSING and a bogus key returns HTTP 403 with API_KEY_INVALID.
