Logs evaluation data under a named project and evaluates it in one call (POST /log_and_evaluate), persisting results so they appear on the managed UpTrain dashboard with real-time monitoring. The same endpoint backs evaluate_experiments for A/B comparison of prompt or model variants.

title: UpTrain Managed Evaluation 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.
