Humanloop LLM Platform API

aid: humanloop:llm-platform
name: Humanloop LLM Platform API
description: The Humanloop REST API and SDKs covered prompts, tools, datasets, evaluations, evaluators,
  and logs for LLM applications. Developers called prompt endpoints from production to capture logs, ran
  evaluations against datasets, and managed versioned prompt configurations. The platform is being sunset
  following the team's acquisition by Anthropic in 2025.
