Mandi Price & Weather App for Farmers

Daily mandi rates and local weather in Marathi, Hindi or English

2-3 weeks build

Overview

A FastAPI service pulls daily commodity prices from the official Agmarknet dataset on the data.gov.in API, cleans them and stores a history in PostgreSQL. The Flutter app lets a farmer pick a state, district and crop to see today's modal, minimum and maximum prices across nearby mandis, a 30-day trend chart and a five-day forecast from OpenWeatherMap, all in Marathi, Hindi or English.

What makes it stand up

  • 01Prices from the official data.gov.in Agmarknet API, not scraping
  • 02Modal, minimum and maximum price by mandi and crop
  • 0330-day price trend chart per commodity
  • 04Five-day weather forecast for the farmer's district
  • 05Full Marathi, Hindi and English UI with large touch targets
