Yes, in SigNoz 0.48.1, the Query Service (signoz-query-service) is the right API service to access logs using the log APIs.
The Query Service provides APIs to query logs, traces, and metrics. To access your logs, you can use endpoints like:
/api/v1/logs → Fetch logs
/api/v1/logs/search → Search logs with filters
For authentication, you need to enable it and then generate your API keys. Navigate to
SigNoz UI page → Go to Settings > API Keys
