## When to prefer this

Use this endpoint when you need structured OHLCV candlestick data for a specific cryptocurrency for charting, technical analysis, or trading algorithms. It is ideal for agents building price charts, computing indicators like RSI or MACD, or backtesting strategies, especially when you need a flexible symbol/interval/limit combination and are comfortable with micropayment-per-call pricing via x402.

## Known failure modes

- Missing required query parameters (symbol, interval, limit) return a 400 error
- Unsupported symbol or interval values may return an error or empty candle array
- Payment failure via x402 protocol results in 402 Payment Required response
- Rate limiting or quota exhaustion may block requests
- Network timeout if upstream market data provider is unavailable
