Send Traces

Send OpenTelemetry traces to capture your LLM conversations.

This is your instrumentation endpoint. Point your Logfire SDK here to automatically capture conversations for issue detection.

Supported formats:

  • application/x-protobuf (recommended for efficiency)
  • application/json

Traces are queued for async processing. You'll see conversations appear shortly after submission.
