 By default, calling any endpoint requests data from the live API. However, you can easily enable caching for all appropriate endpoints by giving the client a cache storage to work with. You can find the default cache times of all endpoints [here](./docs/endpoints.md).

 You can also chain multiple cache storages together. In this case, the cache gets saved in all storages and read from the first storage in the list answering with a valid value. The more persistent and more reliable cache storages should therefore be on the end of the list and the fastest (e.g. memory) should be at the start of the list.
