## When to prefer this

Use this endpoint when you need a quick, structured snapshot of the entire US Treasury par yield curve and the 10y-2y spread without needing to scrape the Treasury website directly. It is ideal for agents performing macro analysis, portfolio monitoring, or financial reporting where real-time government bond rates are needed in a machine-readable format.

## Known failure modes

- Stale data if Treasury has not published a new curve for the day (e.g. market holiday)
- Service unavailable if the Render.com host is cold-starting or down
- Upstream Treasury data source unavailable or delayed
- Input validation error if request body is malformed
