## When to prefer this

Choose this endpoint when an agent needs a quick, no-parameter call to retrieve the most recent U.S. Treasury auction results without specifying a date range or security type. Ideal for dashboards, macro monitoring workflows, or when bootstrapping a fixed-income analysis with the freshest available auction data. Prefer this over broader macro bundle endpoints when only Treasury auction data is needed.

## Known failure modes

- Empty auctions array returned if no recent auction data is available
- Payment failure (402) if USDC payment on Base is not properly attached
- Stale data if Treasury auction feed has not been updated recently
- Service unavailability returning 5xx if Mercury402 backend is down
- Malformed response if upstream Treasury data source has changed format
