-# OpenAI (for some examples) -export OPENAI_API_KEY="your-openai-api-key" - -# Google (for some examples) -export GOOGLE_API_KEY="your-google-api-key" -``` - -### Using .env File - -Create a `.env` file in the project root: - -```bash -OPENROUTER_API_KEY=your-openrouter-api-key -OPENAI_API_KEY=your-openai-api-key -GOOGLE_API_KEY=your-google-api-key -``` - -### Ollama Setup (for ollama_demo) - -If you want to run the Ollama demo, you need to have Ollama installed and running: - -```bash -# Install Ollama (macOS) -curl -fsSL https://ollama.ai/install.sh | sh - -# Start Ollama -ollama serve - -# Pull a model (in another terminal) -ollama pull gemma3:27b -``` - -## Example Structure - -All examples follow the JSON-led pattern: - -1. **Python File** (`example.py`): Contains the action functions and main execution logic -2. **JSON File** (`example.json`): Defines the graph structure and configuration - -### Python File Structure - -```python -# Action functions -def greet_action(name: str, context=None) -> str: - return f"Hello {name}!" - -def calculate_action(operation: str, a: float, b: float, context=None) -> str: -

-### Debug Mode - -To see detailed output from examples, you can run them individually: - -```bash -# Direct Python execution -python3 examples/basic/simple_demo.py - -# Using uv scripts with verbose output -uv run examples --verbose - -# Using bash script with verbose output -./run_examples.sh -v -``` - -### Skipped Examples - -Some examples are automatically skipped by the run scripts: - -- `eval_api_demo`: Requires special evaluation setup -- `json_llm_demo`: Deprecated, use `json_api_demo` instead - -## Contributing - -When adding new examples: - -1. Create both `.py` and `.json` files -2. Follow the established naming convention -3. Include proper error handling -4. Add the example to this README -5.
