# xai-image-gen Generate images using xAI's Grok API (grok-imagine-image model). ## Description Production-ready CLI tool for generating images via xAI's image generation API. Supports multiple output formats, resolutions, and batch generation. Automatically outputs MEDIA: paths for OpenClaw auto-attachment. **Features:** - 🎨 Simple CLI interface: `xai-gen "<prompt>"` - 🖼️ Multiple output formats: URL download, base64 encoding - 🔢 Batch generation (multiple images per prompt) - ⚡ Fast, pure API implementation (Pi-safe) - 🛡️ Robust error handling with user-friendly messages - 📎 Auto-attaches generated images in OpenClaw - 🎯 Uses xAI's native resolution (no size parameter needed) ## Installation ```bash # Navigate to skills directory cd ~/.openclaw/workspace/skills # Clone or copy this skill # (or install via clawhub when published) # Install dependencies pip3 install requests # Ensure the script is executable chmod +x xai-image-gen/xai-gen ``` **Set your xAI API key:** ```bash export XAI_API_KEY="your-api-key-here" ``` Add to your shell profile (`~/.bashrc`, `~/.zshrc`) to persist: ```bash echo 'export XAI_API_KEY="your-api-key-here"' >> ~/.bashrc ``` ## Usage ### Basic Usage ```bash # Generate with simple prompt xai-gen "sunset over mountains" # Custom filename xai-gen "cyberpunk city" --filename city.png # Generate multiple images xai-gen "futuristic vehicle" --n 3 # Base64 output (no download) xai-gen "logo design" --format b64 # Verbose mode xai-gen "space station" --verbose ``` ### Options ``` positional arguments: prompt Text description of the image to generate options: -h, --help Show help message --model MODEL Model name (default: grok-imagine-image) --filename FILENAME Output filename (default: out.png) --format {url,png,b64} Response format: url (download), png (alias), b64 (base64) --n N Number of images to generate (default: 1) --verbose, -v Show detailed progress ``` ### Examples **Generate a meme:** ```bash xai-gen "dumbest trade meme: YOLO panic fail" --filename trade_meme.png ``` **Batch generation:** ```bash xai-gen "logo variations for tech startup" --n 5 # Outputs: out_1.png, out_2.png, out_3.png, out_4.png, out_5.png ``` **High-quality artwork:** ```bash xai-gen "photorealistic portrait of a cat astronaut" --filename cat_astronaut.png ``` ### Integration with OpenClaw The tool outputs `MEDIA: /path/to/image.png` which OpenClaw automatically detects and attaches to messages. Use in agent workflows: ```bash # In an agent skill or automation xai-gen "chart showing Q1 sales data" --filename sales_chart.png # → Image auto-attaches to response ``` ## API Details - **Endpoint:** `https://api.x.ai/v1/images/generations` - **Model:** `grok-imagine-image` - **Authentication:** Bearer token via `XAI_API_KEY` - **Rate Limits:** Subject to xAI API limits (check xAI docs) - **Timeout:** 60s for generation, 30s for download ## Error Handling The tool handles common errors gracefully: - ❌ Missing API key → Clear instructions - ❌ Network errors → Descriptive messages - ❌ API timeouts → Retry suggestions - ❌ Invalid parameters → Usage hints - ❌ File write errors → Permission checks ## Requirements - **Python:** 3.7+ - **Dependencies:** `requests` - **API Key:** xAI API key (get from https://console.x.ai) - **Network:** Internet connection required ## Platform Compatibility - ✅ Linux (tested on Raspberry Pi) - ✅ macOS - ✅ Windows (via WSL or native Python) - ✅ ARM64 / ARMv7 (Pi-safe, pure API calls) ## Troubleshooting **"XAI_API_KEY not found"** ```bash export XAI_API_KEY="xai-..." ``` **"requests library not found"** ```bash pip3 install requests ``` **Permission denied** ```bash chmod +x xai-gen ``` **API errors** - Check API key validity - Verify account has credits - Check xAI status page ## License MIT License - Free to use and modify ## Author Built for OpenClaw by subagent xAI Image Gen Skill Builder ## Version 1.0.0 - Initial release
