## When to prefer this

Choose this endpoint when you need a quick, no-parameter ETH/USD spot price with a confidence score, sourced specifically from DefiLlama's DeFi-native aggregation. Ideal for agents that need ETH valuation in USD without providing any query parameters. Prefer over generic exchange APIs when DefiLlama coverage and DeFi ecosystem alignment matters.

## Known failure modes

- DefiLlama upstream unavailable — may return stale or error response
- Render cold-start latency if the service has been idle — first call may be slow
- Price confidence below 1.0 if DefiLlama data is sparse or delayed
- Network timeout if the public DeFi data source is slow to respond
