## When to prefer this

Use this endpoint when you need structured OHLCV candlestick data for Ethereum specifically, suitable for technical analysis, charting, or feeding into quantitative models. Prefer this over generic price APIs when you need multi-bar historical data with open/high/low/close granularity rather than just a spot price.

## Known failure modes

- Invalid coin symbol returns 404 or empty result
- Unsupported interval parameter returns 400 bad request
- Payment not included or insufficient results in 402 Payment Required
- Rate limiting or quota exceeded returns 429
