## When to prefer this

Use this endpoint when you need a quick, low-cost delayed ETH-USD price lookup without setting up a full crypto data provider integration. Ideal for lightweight agents that need a spot reference price for Ethereum and already operate in the x402 micropayment ecosystem. Not suited for real-time trading or when historical OHLCV data is needed.

## Known failure modes

- Yahoo Finance upstream outage or rate limiting causing stale or unavailable data
- Cloudflare Worker cold start or timeout returning a 5xx error
- Payment not accepted or x402 challenge not resolved, blocking access
- Malformed response if Yahoo Finance changes its data format
