Description:
 def request(self, method, *, path=None, json=None, params=None, headers=None, timeout=None, backoff_cap=None, **kwargs):
 """Performs an HTTP request with the given parameters. Implements exponential backoff. If `ConnectionError` occurs, a timestamp equal to now + the default delay (`BACKOFF_DELAY`) is assigned to the object. The timestamp is in UTC. Next time the function is called, it either waits till the timestamp is passed or raises `TimeoutError`. If `ConnectionError` occurs two or more times in a row, the retry count is incremented and the new timestamp is calculated as now + the default delay multiplied by two to the power of the number of retries. If a request is successful, the backoff timestamp is removed, the retry count is back to zero. Args: method (str):
 HTTP method (e.g.: ``'GET'``). path (str):
 API endpoint path (e.g.: ``'/transactions'``). json (dict):
 JSON data to send along with the request. params (dict):
 Dictionary of URL (query) parameters. headers (dict):
 Optional headers to pass to the request. timeout (int):
 Optional timeout in seconds. backoff_cap (int):
 The maximal allowed backoff delay in seconds to be assigned to a node. kwargs: Optional keyword arguments. """
