## When to prefer this

Use this endpoint when you need logarithmic cycle valuation bands (rainbow chart) specifically for Bitcoin or Ethereum from CoinStats. Prefer this over general price endpoints when the user wants to understand long-term valuation context, cycle positioning, or bubble vs. undervaluation analysis rather than just a spot price.

## Known failure modes

- Invalid coinId returns 404 or empty response
- Unsupported coin (only BTC/ETH likely supported) returns error
- Payment failure via x402 protocol returns 402
- Network timeout or upstream CoinStats data unavailability returns 503
