• Use faster ujson instead of stdlib json to decode the responses

Methods summary

__init__(rpc_config_line[, http_adapter, ...])	Set up a factory.
get_total_api_call_counts()	Sum API call counts across all threads

__init__(rpc_config_line, http_adapter=None, thread_local_cache=False, api_counter=False)
