Troubleshooting

"No API key found"

• Check the API key has no extra spaces
• Verify it starts with sk-proj-

"Error fetching website"

• Check your internet connection
• Try a different city URL
• Some websites may temporarily block requests

No good recommendations

• Try adjusting your budget or requirements
• Check if the website loaded properly (look at content length)
• Try a different city with more properties

Possible Improvements

• Make it interactive (ask for user input)
• Support multiple property websites
• Add price tracking over time
• Include property images in analysis
• Create a simple web interface
