Since the API is hosted on Renderer, the loading time could take up to 2 minutes on the initial request.

Overview

The Car Price Predictor API is a backend service developed using FastAPI. It serves as the backend for the Car Price Predictor application, allowing users to submit data about their vehicles and receive price predictions.
