Project Samarth - Intelligent Q&A System for Indian Agriculture

🌾 PRODUCTION READY: Live data.gov.in API integration, premium frontend, cloud deployment, and enterprise-grade monitoring.

Live Demo API Status GitHub Actions

🚀 Quick Start

🌐 Live Demo (Recommended)

🐳 Docker Compose

docker-compose up --build

💻 Local Development

# Backend
python run_server.py

# Frontend (new terminal)
cd frontend/nextjs
npm install && npm run dev

💡 Sample Questions

🔥 Live Data (Real-time API)

  • "What are the current crop prices in Maharashtra?"
  • "Show me latest market rates for Punjab"
  • "Compare recent commodity prices across states"
  • "Live mandi prices for wheat"

📊 Historical Data (2001-2014)

  • "Compare the average annual rainfall in Maharashtra and Punjab"
  • "Which state has the highest rice production?"
  • "Analyze the production trend of cotton from 2010 to 2014"
  • "Correlation between rainfall and crop production"

💡 Tip: Use keywords like current, latest, recent, live for real-time data, or specify years for historical analysis.
