U.S. Treasury Fiscal Data · Rate Limits

Fiscaldata Rate Limits

Treasury Fiscal Data does not publish a fixed numeric rate limit for its public API, and no API key or account is required. Access is open. In practice, clients should be considerate of a shared public government service: request only the fields you need with the fields parameter, filter server-side with the filter parameter, and page through large result sets with page[size] (maximum 10000 records per page) rather than pulling everything at once. Excessive or abusive request volume may be throttled or blocked at the network edge, but no documented per-key quota exists because there are no keys.

Fiscaldata Rate Limits is the machine-readable rate-limit profile for U.S. Treasury Fiscal Data on the APIs.io network, in the API Commons Rate Limits shape.

It captures 2 rate-limit definitions, measuring requests and records.

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.

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

Limits

API Requests public
requests
not published
No fixed numeric request-rate limit is documented; access is unauthenticated and open.
Page Size request
records
10000
Maximum records returned per request via page[size]; paginate with page[number].

Policies

Server-Side Filtering
Use fields, filter, and sort to reduce payload size rather than fetching entire datasets and filtering client-side.
Pagination
Retrieve large datasets in pages of up to 10000 records using page[number] and page[size].
Polling Cadence
Poll no faster than the underlying report's update cadence (daily, monthly, or quarterly); more frequent requests return no new data.
Backoff Strategy
Implement exponential backoff with jitter and honor Retry-After on any 429 or transient 5xx responses from this shared public service.
