# 🚀 Deploying to Hugging Face Spaces

## Quick Setup

1. **Create a new Space**:
   - Go to https://huggingface.co/new-space
   - Choose "Docker" as SDK
   - Set visibility to "Public"

2. **Upload Files**:
   Upload these files to your Space repository:
   ```
   app.py
   events.py
   requirements.txt
   Dockerfile
   .dockerignore
   templates/
   static/
   ```

3. **Set Environment Variables**:
   In your Space settings, add these secrets:
   
   **Required:**
   - `PAY_TO_ADDRESS`: Your wallet address for receiving payments
   - `X402_NETWORK`: `base-sepolia`
   
   **Optional (for revenue splitting):**
   - `CDP_API_KEY_ID`: Your CDP API key ID
   - `CDP_API_KEY_SECRET`: Your CDP API key secret  
   - `CDP_WALLET_SECRET`: Your CDP wallet secret
   - `DEV_WALLET`: Developer wallet address
   - `HF_WALLET`: Hugging Face wallet address
   - `AWS_WALLET`: AWS wallet address
   
   **Optional (for image generation):**
   - `AWS_ACCESS_KEY_ID`: Your AWS access key
   - `AWS_SECRET_ACCESS_KEY`: Your AWS secret key
   - `AWS_REGION`: `us-east-1`

4. **Build and Deploy**:
   - Push files to your Space repository
   - HF Spaces will automatically build using the Dockerfile
   - First build takes ~5-10 minutes (downloading models)
   - Subsequent builds are faster due to Docker layer caching

## Testing

1. Visit your Space URL
2. Connect MetaMask to Base Sepolia
3. Get testnet USDC from [Base Sepolia faucet](https://www.coinbase.com/faucets/base-ethereum-sepolia-faucet)
4. Test the three services:
   - Text Generation ($0.01)
   - Sentiment Analysis ($0.005) 
   - Image Generation ($0.02)

## Troubleshooting

- **Build fails**: Check logs for missing dependencies
- **Models loading slowly**: First startup takes time to download models
- **Payment fails**: Ensure MetaMask is on Base Sepolia with testnet USDC
- **Image generation fails**: Check AWS credentials and Bedrock model access

## Performance Notes

- **Memory**: ~4GB for all models
- **Startup**: ~30-60 seconds after build
- **Cold start**: ~10-20 seconds on first request
