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. Request bodies are limited to 128 MiB on the wire.

curl -X POST "https://loading/v1/traces" \  -H "Content-Type: application/json" \  -d '{}'
