## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.05) delayed DXY spot quote for macro analysis, dollar strength monitoring, or as context for forex/commodity trading decisions. Prefer this over full market data APIs when you only need the Dollar Index and want minimal cost and complexity. Note the data is delayed (not real-time), so avoid for latency-sensitive HFT use cases.

## Known failure modes

- Yahoo Finance upstream unavailable — returns error or stale data
- Rate limiting or payment failure with x402 protocol — returns 402 Payment Required
- Delayed data may lag real-time market conditions by 15-20 minutes
- Network timeout from Cloudflare Workers proxy layer
