  title: Lakera Guard Policies API
  description: 'Lakera Guard is an AI-native security platform that screens LLM application

    inputs and outputs for prompt attacks, data leakage, content violations, PII

    exposure, and malicious links. The Guard API exposes a single screening

    endpoint that accepts OpenAI-style chat messages and returns a flagged

    response, plus a results endpoint that returns detector confidence levels

    without making a runtime decision.
