Example prompt: Can you pull the US Treasury auction data for January 15, 2025 and tell me what securities were auctioned that day?

## When to prefer this

Use this endpoint when you need Treasury auction data for a specific calendar date rather than aggregated or range-based data. Ideal for day-specific lookups, historical research, or tracking what was issued on a particular date. Prefer this over the avg-interest-rates or debt endpoints when you need auction-level granularity tied to a specific date.

## Known failure modes

- Invalid or malformed date format returns an error
- No auctions on the requested date (weekends, holidays) may return empty results or 404
- Future dates may return no data or an error
- Network timeout or upstream Treasury data source unavailability
