From approximately 1550 until 1610 UTC, the LangSmith API, UI, and Run Ingest were intermittently unavailable due to an API error from our metering provider that caused a 500 response on the /orgs/current endpoint and a 403 response on some calls to other LangSmith API endpoints including /runs and /runs/batch.
These errors are no longer occurring and we are working to reduce our dependency on our metering provider for the majority of these calls in the future.
