Ferc Rate Limits

FERC publishes one rate limit, on the Open Data API: 1,000 requests per hour per API key, reset on a rolling basis, enforced by the api.data.gov API Umbrella gateway. Exceeding it temporarily blocks the key. Higher limits are granted by contacting support — no published tier ladder. The eForms XBRL API publishes no rate limit.

Ferc Rate Limits is the rate-limit profile for FERC on the APIs.io network — every limit transcribed verbatim from the provider’s own documentation on 2026-07-27.

It captures 1 rate-limit definition, including Open Data API requests — The default rate limit for each user is 1,000 requests per hour and is reset on a rolling basis.

Limit state is signalled in the limit, remaining, and requestId response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting, Open Data, and Government.
