Your code looks correct and well-structured. The API route properly handles the OpenAI request with good error handling. Let me add some debug logging to help verify the API key is being read correctly and provide better debugging information when you test:

I've enhanced the API route with detailed debug logging to help verify the API key configuration. Here's what to do now:

After Adding Your NEW API Key to Vercel:

1. Go to your Vercel project dashboard
2. Check Settings > Environment Variables for OPENAI_API_KEY
3. Click Redeploy (important - env vars only load on deploy)
4. Go to Deployments > Functions > Logs to see the debug output
5. Test the chat on your live site

What the Logs Will Show:

• Whether the API key exists
• The key length and prefix (safely truncated)
• The exact OpenAI response status
• Specific error messages if something fails

The debug logs will appear in your Vercel Functions logs and will help pinpoint exactly what's happening. Once confirmed working, I can remove the debug statements.
