## Overview

This repository is a small FastAPI-backed agentic query service. A client submits a query to the `/generate/` endpoint; the API delegates it to a LangGraph workflow, which invokes an agent that queries the configured Groq chat model and returns the response. `app/workflows.py` also exposes a thin wrapper around the same workflow, but the API route calls the runner directly. The README describes agent CRUD endpoints, but the sampled application source implements only `/generate/` and `/`.

Main entry points: [`app/agent.py`](https://github.com/holamexico/end-to-end-agentic-ai-fastapi-docker-project/blob/main/app/agent.py) (Graph runner), [`app/main.py`](https://github.com/holamexico/end-to-end-agentic-ai-fastapi-docker-project/blob/main/app/main.py) (FastAPI routes), [`app/workflows.py`](https://github.com/holamexico/end-to-end-agentic-ai-fastapi-docker-project/blob/main/app/workflows.py) (Workflow wrapper)
