Why does this limit matter?
Server-side polling and high-traffic evaluation can consume flag capacity independently from captured events.
This value is scoped to Cloud free tier; a different plan, runtime, model, endpoint, region, or account can produce a different effective constraint.
What should you check?
- Measure evaluations by SDK, environment, flag, and server/client path.
- Confirm the exact plan, model, runtime, endpoint, region, and account that serve the failing workload.
- Record the observed value, response headers or configuration, timestamp, and source without logging secrets.
Important caveats
- Local evaluation and implementation choices affect request volume.
- Treat the official source and live account configuration as authoritative if they differ from this verified snapshot.
HyperObserve reports the documented platform constraint. Your application, SDK, gateway, provider, region, or account can impose a lower effective limit.
