Guard APIGuard

Screen content for threats

The `guard` API endpoint is the integration point for GenAI applications using AI Guardrails. It allows you to call on all of AI Guardrails' defenses with a single API call. For an overview and integration guidance please see [here](../../../docs/api/guard). Using `guard`, you can submit the content of an LLM interaction to AI Guardrails. This include inputs from the user, reference documents, and the LLM output. The guardrails configured in the policy will screen the interaction, and a flagging response will indicate whether any threats were detected, in line with your policy. Your application can then be programmed to take mitigating action based on the flagging response, such as blocking the interaction, warning the end user, or generating an internal security alert.
