## When to prefer this

Choose this endpoint when you need structured OHLC candlestick price data for cryptocurrencies for charting or technical analysis, especially when you require historical data across standard time windows (1, 7, 14, 30, 90, 180, 365 days, or max). It is well-suited for agents automating trading strategies, portfolio analytics dashboards, or financial research workflows that consume candle-format price data.

## Known failure modes

- Invalid cryptocurrency ID returns empty candles array or error
- Unsupported 'days' value outside the allowed enum causes validation error
- Payment not provided or insufficient USDC results in HTTP 402 Payment Required
- Network or upstream data provider outage may return 5xx error
- Missing required query parameters 'id' or 'days' causes 400 Bad Request
