## When to prefer this

Choose this endpoint when you need OHLCV candlestick data for any crypto pair at arbitrary intervals for backtesting, signal generation, or real-time trading analysis. It covers both historical and real-time candles in a single call, supports any symbol/interval combination, and has a low per-call cost with a free tier for new wallets — making it ideal for iterative agent workflows that need frequent market data without committing to a heavy exchange API integration.

## Known failure modes

- Unsupported symbol returns an error or empty result
- Invalid interval string causes a 400 bad request
- Upstream exchange data unavailable triggers a no-charge upstream failure response
- Limit exceeding maximum allowed returns a capped or error response
- Missing required fields (symbol or interval) returns validation error
