Reports API

A small FastAPI service that exposes a paginated /reports endpoint backed by a deterministic in-memory dataset.

Layout

app/
├── __init__.py
├── data.py        # Seed dataset (120 rows, deterministic)
├── models.py      # Pydantic models — internal vs public
├── reports.py     # Filter / sort / pagination query layer
└── main.py        # FastAPI HTTP layer

Requirements

• Python 3.10+
• pip

Setup

git clone https://github.com/IITMBSMLOps/SpecDrivenDevelopmentBase.git
cd SpecDrivenDevelopmentBase

python3 -m venv .venv
source .venv/bin/activate          # Windows: .venv\Scripts\activate

pip install -e .

Run the API

uvicorn app.main:app --reload --port 8000

Then hit it from another terminal:

curl "http://localhost:8000/health"
curl "http://localhost:8000/reports?limit=3" | python -m json.tool
