+# Structured Output – Union Events API
+
+## Installation
+
+```bash
+# Create a virtual environment (optional but recommended)
+python -m venv venv
+source venv/bin/activate   # On Windows use `venv\Scripts\activate`
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+The repository contains a single `main.py` script that demonstrates how to parse a raw log into a list of typed events using LangChain’s structured output and Pydantic v2. The only external dependency required is **langchain-openai** (or **langchain-ollama** if you prefer a local model). The `deepagents` package has been removed because it is not part of the allowed stack.
+
+## Usage
+
+```bash
+python main.py
+```
+
+You can also pass a custom log file path as a command‑line argument:
+
+```bash
+python main.py --log custom_log.txt
+```
+
+The script will output a table of parsed events and their JSON representations.
+

+
+**Note**: If you encounter any issues with the OpenAI API key, set the environment variable `OPENAI_API_KEY` before running the script.
