Example use cases

Technical details
Endpoint
POSThttps://api.vextorium.com/v1/us-national-debt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official, Treasury-sourced US national debt figures with breakdown by public/intragovernmental holdings and change metrics over 30-day and 1-year windows. It is the right choice over general web search when you need structured, machine-readable numeric data with consistent schema. Prefer it over other Vextorium economy endpoints when the specific need is national debt (not interest rates, CPI, or other economic indicators).
Side effects
- No input body required but malformed request structure may return 400 error
- Data may lag by one business day if Treasury hasn't published the latest figure
- Negative 30-day change is valid (debt can temporarily decrease) — not an error
- Service unavailable (503) if upstream Treasury Fiscal Data API is down
