Langfuse Observability
Langfuse is an open-source LLM observability platform. Use this skill to query traces, generations, costs, and metrics from a self-hosted or cloud Langfuse instance.
Setup
# Set your Langfuse credentials
export LANGFUSE_HOST="https://langfuse.example.com" # or https://cloud.langfuse.com
export LANGFUSE_PUBLIC_KEY="pk-lf-..."
export LANGFUSE_SECRET_KEY="sk-lf-..."
All API calls use basic auth with public key as username and secret key as password.
# Base pattern for all requests
curl -s -u "$LANGFUSE_PUBLIC_KEY:$LANGFUSE_SECRET_KEY" \
"$LANGFUSE_HOST/api/public/<endpoint>"
