Example prompt: Can you get me the hourly BTC candlestick data for the last 7 days from Carbon Cashmere's OHLCV endpoint so I can run some technical analysis?

## When to prefer this

Use this endpoint when you specifically need Bitcoin OHLCV candlestick data with flexible interval granularity (15m to 1d) and up to 90 days of history. Prefer this over generic price endpoints when you need structured OHLCV format suitable for technical analysis, charting, or backtesting. Note that this is BTC-only; use other endpoints for multi-coin data.

## Known failure modes

- days parameter out of range (must be 1-90) returns validation error
- invalid interval value (must be 15m, 1h, 4h, or 1d) returns error
- payment failure or insufficient USDC balance blocks request (x402 payment required)
- response truncated for large datasets — check _truncated flag and _originalSize
