import os
import requests
endpoint = "https://api.zenguard.ai/v1/detect/keywords"
headers = {
"x-api-key": os.getenv("ZEN_API_KEY"),
"Content-Type": "application/json",
}
data = {
"messages": ["You know, batman is my favorite hero."]
}
response = requests.post(endpoint, json=data, headers=headers)

print("Keywords detected.")

"is_detected": true,
"block": [],
"warn": [
"Batman"
],
"redact": [
"hero -> mango"
],
"sanitized_message": "You know, Batman is my favorite mango."
