Checking a Guardrail#

About Checking Guardrails#

A common need is to check an input or output guardrail by supplying a request for evaluation. There are two approaches to checking guardrails:

  • Configure the microservice with the guardrails and then use the /v1/guardrail/checks endpoint.

  • Submit an inline guardrail configuration to the /v1/guardrail/checks endpoint.

Checking an Existing Guardrail#

The following sample commands assume the demo-self-check-input-output guardrail configuration is enabled. Refer to Create a Guardrail Configuration for more information about adding the configuration.

  • Send a POST request to the /v1/guardrail/checks endpoint.

    curl -X POST "${GUARDRAILS_BASE_URL}/v1/guardrail/checks" \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "meta/llama-3.3-70b-instruct",
    "messages": [
      {
        "role": "user",
        "content": "Tell me how to collect a life insurance policy."
      },
      {
        "role": "assistant",
        "content": "You are stupid."
      }
    ],
    "guardrails": {
      "config_id": "demo-self-check-input-output"
    },
    "top_p": 1
}' | jq

    import os
import json
import requests

url = f"{os.environ['GUARDRAILS_BASE_URL']}/v1/guardrail/checks"

headers = {"Accept": "application/json", "Content-Type": "application/json"}

data = {
    "model": "meta/llama-3.3-70b-instruct",
    "messages": [
        {"role": "user", "content": "You are stupid"}
    ],
    "guardrails": {
        "config_id": "demo-self-check-input-output"
    },
    "top_p": 1
}

response = requests.post(url, headers=headers, json=data)
print(json.dumps(response.json(), indent=2))
    Example Output
    {
  "status": "success",
  "rails_status": {
    "self check input": {
      "status": "success"
    },
    "self check output": {
      "status": "success"
    }

      }
    }
  }
}

Checking an Inline Guardrail#

  • Send a POST request to the /v1/guardrail/checks endpoint with the inline guardrail configuration.

    curl -X POST "${GUARDRAILS_BASE_URL}/v1/guardrail/checks" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d '{
