UpTrain Root Cause Analysis API

  title: UpTrain Managed Evaluation Auth Root Cause Analysis API
  description: Managed HTTP API for UpTrain, the open-source (Apache-2.0) LLM evaluation platform. The API grades supplied LLM input / output / context rows against a list of named checks (context relevance, factual accuracy, response completeness, conciseness, tonality, prompt injection, hallucination and more), logs results to a named project for dashboard monitoring, and performs root cause analysis on failures. These paths correspond to the public endpoints called by the uptrain Python package's APIClient (uptrain/framework/remote.py), rooted at {server_url}/api/public. The default managed server is https://demo.uptrain.ai. Requests are authenticated with an uptrain-access-token header.
