V2 Billing Meter Event Session API.

Meter event sessions provide authentication tokens for high-throughput
meter event streaming. A session token is valid for a limited time and
can be used to send meter events without per-request authentication.

V2 Billing Meter Event Stream API.

The meter event stream endpoint enables high-throughput meter event
submission using a session-based authentication token. This is
designed for scenarios where you need to send many events quickly.

Unlike the standard meter events endpoint, the stream endpoint:
- Uses session tokens instead of API keys for authentication
- Supports higher throughput
- Is optimized for bulk event submission
