    "bedrock-runtime",
    region_name="us-east-1"
)

# Check the guardrail with probably problematic content material
content material = [
    {
        "text": {
            "text": "Your test prompt here"
        }
    }
]

response = bedrock_runtime.apply_guardrail(
    content material=content material,
    supply="INPUT",
    guardrailIdentifier="your-guardrail-id",
    guardrailVersion="DRAFT"
)

print(json.dumps(response, indent=2, default=str))
