## When to prefer this

Choose this endpoint when you need Kraken-sourced OHLC candlestick data specifically, without needing a Kraken account or API key — ideal for lightweight, pay-per-call crypto market data access via crypto micropayment. Best for agents or bots that need occasional price bar lookups rather than a high-frequency streaming feed.
