## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to U.S. national debt data without managing API keys or subscriptions. Ideal for AI agents that need on-demand federal fiscal data as part of economic research, financial dashboards, or policy monitoring workflows. Prefer this over web scraping Treasury.gov when you need structured JSON output with minimal setup.

## Known failure modes

- Empty data array if federal source is unavailable or rate-limited
- Payment failure if USDC balance is insufficient or x402 header is malformed
- success: false if upstream Treasury data API is down
- Stale data if federal source has not been recently updated
- HTTP 402 if payment is not included or rejected
