Cryptowat.ch is a cryptocurrency charting and trading platform owned by Kraken. Cryptowatch contains cryptocurrency charts for most cryptos and exchanges.

Currently there aren't any private APIs. API is limited by CPU allowance instead of fixed amount of calls. Some calls take more time than others. Every client has allowance of 8 seconds of CPU time per hour.
For that we have Allowance class which is updated by every call. Class contains previous cost time and remaining time (in nanoseconds).

What API offers

All types can be called as a single object or as a list. Script automatically converts JSON string into object.
If you call a function which returns a list of objects you need to call a function which returns a single object by taking its route from list of objects.
