Federal Housing Finance Agency (FHFA) · Rate Limits

Fhfa Rate Limits

FHFA does not publish formal rate limits for its public data API endpoints and dataset downloads. As a federal government agency, FHFA data is freely accessible to the public. Standard web server infrastructure limits apply, and the agency reserves the right to modify, limit, or terminate access at any time per the API Terms of Service. Consumers should implement reasonable request pacing and caching to avoid placing undue load on FHFA servers.

Fhfa Rate Limits is the machine-readable rate-limit profile for Federal Housing Finance Agency (FHFA) on the APIs.io network, in the API Commons Rate Limits shape.

It captures 1 rate-limit definition, across the public tier, measuring requests_per_minute.

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

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Housing Finance, House Price Index, Mortgage, Government, and GSE.

Policies

Attribution Required
All applications and services using FHFA data must display the notice: "This product uses FHFA Data but is neither endorsed nor certified by FHFA."
Responsible Use
Consumers should cache responses locally where feasible, since FHFA datasets are updated on monthly or quarterly schedules rather than in real time. Avoid repeatedly downloading large files unnecessarily.
Backoff Strategy
Clients receiving 429 or 503 responses should implement exponential backoff with jitter and honor any Retry-After header returned.
Content Integrity
Users must not falsely represent or modify FHFA data content while attributing it to FHFA as the source.
