Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-fiscal-interest-expenseWhen to prefer
Choose this endpoint when you need structured, authoritative US Treasury interest expense figures broken out by debt security type (bills, notes, bonds, TIPS, floating rate notes). It is ideal for fiscal analysis, budget monitoring, and debt-service tracking, especially when you need both monthly and fiscal-year-to-date views without building your own FiscalData integration. Prefer this over building a raw FiscalData query when you want a pre-filtered, sorted, ready-to-consume result.
