## Overview

This is a browser-based news aggregator. A user opens the frontend, which automatically requests top headlines; users can also choose a suggested topic or enter a keyword. The FastAPI backend queries NewsAPI and returns JSON, and the frontend renders article cards or displays an error. The README also documents responsive desktop/mobile presentation and environment-based API-key configuration. Source excerpts show the frontend requests and backend API calls; the README supports the user-facing capabilities and workflow, but does not expose the HTML-to-script wiring.

Main entry points: [`frontend/script.js`](https://github.com/gungunrathore2525-lang/news-aggregator/blob/main/frontend/script.js) (Search and fetch), [`backend/main.py`](https://github.com/gungunrathore2525-lang/news-aggregator/blob/main/backend/main.py) (FastAPI routes), [`frontend/index.html`](https://github.com/gungunrathore2525-lang/news-aggregator/blob/main/frontend/index.html) (News page), [`frontend/style.css`](https://github.com/gungunrathore2525-lang/news-aggregator/blob/main/frontend/style.css) (Responsive styles)
