Department Of The Treasury Rate Limits

Treasury APIs split into two regimes. Fiscal Data and SAM.gov Entity Management are fronted by api.data.gov, which enforces a default 1,000-requests-per-hour limit per developer key (raisable via support). OFAC's Sanctions List Service and TreasuryDirect open feeds are unauthenticated and bounded by fair-use rather than per-key quotas. api.data.gov surfaces 429 with X-RateLimit-* headers; OFAC and TreasuryDirect use standard server throttling.

Department Of The Treasury Rate Limits is the machine-readable rate-limit profile for Department of the Treasury on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, across the api-data-gov and open tiers, measuring requests_per_hour and requests_per_minute.

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

Tagged areas include Federal Government, Finance, Sanctions, Open Data, and Rate Limiting.

Policies

api.data.gov Key Pattern
Fiscal Data and SAM.gov enforce limits at the api.data.gov gateway; excess returns 429. Increases must be requested via api.data.gov support.
OFAC SLS Bulk Pattern
OFAC publishes daily refreshed lists; consumers should download once per day rather than poll. Fair-use limits apply at the network edge.
Backoff Strategy
On 429 / 503 implement exponential backoff with jitter, honoring Retry-After when present.
Caching Encouragement
Fiscal Data datasets are stable on a daily-or-weekly cadence; cache results aggressively to reduce gateway load.
