How this service works
US federal interest expense on public debt: latest month, fiscal-year-to-date and split by security type.
Output
Returns a JSON object with: the monthly US federal interest expense in USD, fiscal-year-to-date interest expense in USD, an array of interest expense broken down by security type (each with monthly and FYTD figures), the record date, data source URL, a plain-language summary, a verdict label, a degraded-data flag, threshold values for context, and attribution/disclaimer text.
Example use cases
Monthly debt cost tracking for macro dashboard
“Pull the latest monthly interest expense the US is paying on its public debt, including the fiscal-year-to-date figure and how it breaks down across different Treasury security types.”
Alerting when interest payments spike
“Check the most recent US federal interest expense data and tell me if it's flagged as unusually large based on the built-in thresholds — I want to know if this month's number is abnormal.”
Macro research on US debt burden
“I'm writing a report on US fiscal sustainability — can you get me the current monthly interest expense on public debt, the year-to-date total, and the breakdown by security type like bills, notes, and bonds?”
Technical details
Endpoint
GEThttps://treasury-macro.x402tookit.com/us-interest-expense?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, structured US federal interest expense data broken down by security type and fiscal-year-to-date, sourced from the US Treasury. Prefer it over generic financial data APIs when you specifically need official government debt interest cost figures with built-in anomaly thresholds and a plain-language verdict summary. It is not suitable for historical time series, individual bond pricing, or non-US sovereign debt.
Side effects
- Stale or delayed Treasury source data may result in degraded=true flag with a warning
- Treasury data publication lag may cause null values for the most recent month
- Network or upstream API failure returns an error response with no financial data
- Invalid query parameters may be silently ignored (view param is decorative only)
