from langchain_community.tools import GooglePlacesTool
import os
if 'GOOGLE_API_KEY' not in os.environ:
    print("⚠️ Warning: Environment variable 'GOOGLE_API_KEY' not found.")
    print("   Please set up your Google Cloud API key first.")
try:
    places = GooglePlacesTool()
except Exception as e:
    print(f"❌ Failed to initialize GooglePlacesTool: {e}")
    exit()
search_query = "museums in New York City"
print(f"? Searching using GooglePlacesTool: '{search_query}'...")
result = places.run(search_query)
print("\n--- Search results ---")
print(result)
