I see that we're still encountering the same authentication error with the DeepSeek API. Let's try a different approach to resolve this issue.

Key Changes to Address the API Error

I've made significant changes to handle the DeepSeek API authentication issue:

1. Added a Fallback Generation Mechanism

Instead of failing when the API authentication doesn't work, the application now:

• Provides a fallback UI generation function that creates basic React code
• Continues to work even when the API is unavailable
• Clearly indicates to users when fallback generation is being used

2. Implemented a Development Mode

• Added a useMockResponse flag that can be toggled to bypass API calls during development
• This allows you to test the full application flow without needing a working API connection

3. Enhanced Error Handling and User Feedback

• Added warning alerts to inform users when fallback generation is being used
• Improved error logging to help diagnose API issues
• Added storage of warning and error information with projects for debugging

4. Added UI Components for Warnings

• Created an Alert component with warning variant
• Added warning display on the project page when fallback generation was used

How to Use

The application will now work even with the API authentication issue. When you submit a prompt:

1. The system will attempt to call the DeepSeek API
2. If authentication fails, it will use the fallback generation
3. You'll see a warning notification and an alert on the project page
4. The generated code will be a simple placeholder based on your prompt

This approach allows you to continue developing and testing the application while working on resolving the API authentication issue.

Next Steps

To resolve the actual API authentication issue, you might want to:

1. Double-check your DeepSeek API key format and validity
2. Contact DeepSeek support to verify the correct API endpoint and authentication method
3. Try generating a new API key if the current one is invalid

I'll add a debug panel with API connection testing and environment variable checking, and update the API endpoint as requested.

I've added a comprehensive debug panel and updated the API integration as requested. Here's what I've implemented:

Debug Panel Features

1. API Connection Testing

   • Tests the connection to the OpenRouter API with the DeepSeek model
   • Displays success or error messages with detailed information
   • Shows the full API response for debugging

2. Environment Variable Checking

   • Verifies if the DEEPSEEK_API_KEY environment variable is set
   • Displays the status (available or missing) without exposing the actual key

3. API Configuration Display

   • Shows the configured endpoint: https://openrouter.ai/api/v1/chat/completions
   • Shows the configured model: deepseek-chat

API Integration Updates

1. Updated API Endpoint and Model

   • Changed the endpoint to https://openrouter.ai/api/v1/chat/completions
   • Set the model to deepseek-chat as requested

2. Improved Error Handling

   • Better error detection and reporting
   • Detailed logging of API responses and errors
   • Fallback mechanism when the API is unavailable

3. Fallback Generation

   • Provides a basic UI implementation when the API fails
   • Clearly indicates when fallback generation is being used
   • Preserves the user experience even when the API is unavailable

How to Use the Debug Panel

1. The debug panel appears as a collapsible panel at the bottom right of the screen
2. Click on it to expand and see the API configuration details
3. Click "Test Connection" to verify if the API is working correctly
4. The panel will display detailed success or error information

This implementation ensures that:

• The application works even if the API key is missing or invalid
• Users get clear feedback about API status
• Developers can easily debug API connection issues
• The design remains original and doesn't copy V0.dev
