## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01 USDC) lookup of the US 10-year Treasury yield without setting up a full financial data subscription. It is ideal for macro dashboards, DCF valuation inputs, risk-free rate references, and bond market monitoring. Note that data is delayed, so avoid this if real-time precision is required for live trading decisions.

## Known failure modes

- Network timeout from Cloudflare worker
- Payment failure (402) if x402 micropayment of $0.01 USDC is not properly included
