How to detect:

The v2 Metrics API is only available on Langfuse Cloud. Self-hosted deployments cannot access v2 endpoints and must use v1 API.

Recommended action:

Continue using v1 Metrics API for self-hosted deployments. Monitor Langfuse announcements for migration path to v2 on self-hosted. Consider migrating to Langfuse Cloud if v2 performance improvements are critical.
