  Google Gemini gives free limited tokens. But for comfortable usage of Gemini's models in VoxWrite, please keep your balance positive.

## API Key Format

Google Gemini API keys follow this format:
```
AIzaSyXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
```

Make sure to copy the entire key including the `AIza` prefix.

## Key Security

### Best Practices

- ✅ **Never share** your API key publicly
- ✅ **Store securely**: Keep it in a password manager
- ✅ **Use unique keys**: Create different keys for different apps
- ✅ **Monitor usage**: Check your Google Cloud Console regularly
- ✅ **Set quotas**: Configure usage limits in Google Cloud

### What to Do If Compromised

1. **Delete immediately**: Remove the compromised key in Google AI Studio
2. **Create new key**: Generate a fresh API key
3. **Update VoxWrite**: Add the new key to your settings
4. **Check billing**: Review your Google Cloud usage for any unusual activity

## Usage & Billing

- Google charges based on tokens used (input + output)
- Pricing varies by model
- Free tier available with limited requests per minute
- View detailed usage in Google Cloud Console

## Troubleshooting

### "Invalid API Key" Error

- Verify you copied the entire key (starts with `AIza`)
- Check for extra spaces or characters
- Ensure the key hasn't been deleted
- Verify the API is enabled in your Google Cloud project
- Try generating a new key

### "Quota Exceeded" Error

- Check your free tier limits
- Wait for the rate limit to reset (usually per minute)
- Consider enabling billing for higher limits
- Upgrade your quota in Google Cloud Console

### Connection Issues

- Check your internet connection
- Verify Google AI services status
- Ensure the Generative Language API is enabled in your project
- Check if you need to enable billing for your project
