Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-fiscal-treasury-rates-of-exchangeWhen to prefer
Choose this endpoint when you need the official US government exchange rates for federal accounting and reporting purposes rather than live market rates. It is authoritative for compliance, grant reporting, government contracting, and any scenario where the regulatory requirement is specifically the US Treasury Fiscal Data rate, not a commercial FX rate.
