# meter_event_stream.py - use the high-throughput meter event stream to report create billing meter events.
#
# In this example, we:
#   - create a meter event session and store the session's authentication token
#   - define an event with a payload
#   - use the meter_event_stream service accessor in StripeClient to create an event stream that reports this event
#
# This example expects a billing meter with an event_name of 'alpaca_ai_tokens'.  If you have
# a different meter event name, you can change it before running this example.
