Accuracy and Limitations

• Currency Converter API's free API service, which Kraken uses, is updated once per hour, according to their website. This means that the data that Kraken provides does not reflect live market rates.
• Currency Converter API's free API service is restricted to 100 API calls per hour. If you use Kraken more than 100 times per hour, you risk having your API key banned by Currency Converter.
