Task-6 Learn APIs and FastAPI

Vemuri priya requested to merge Task-6 into main

Description

This Merge Request implements Task 6 – Learn APIs and FastAPI by exploring public API usage and developing a simple backend application using FastAPI. The implementation demonstrates API concepts such as handling requests, returning JSON responses, and creating custom API endpoints.

Features Implemented

1. Public API Integration

  • Integrated a public weather API using OpenWeather API.
  • Implemented functionality to fetch weather details for a given city.
  • Explored API request handling, JSON responses, and API usage limits.

2. FastAPI Application Development

  • Created a basic FastAPI application with multiple endpoints.

Greeting Endpoint

  • Implemented:
GET /greet/{name}
  • Returns a personalized greeting response in JSON format.

Village Management APIs

  • Implemented:
GET /villages
  • Returns the list of village names.
POST /add-village
  • Adds a new village to the in-memory list.

3. API Testing

  • Tested API endpoints using:

    • FastAPI Swagger UI
    • Postman
    • Browser-based requests

Technologies Used

  • Python
  • FastAPI
  • Uvicorn
  • OpenWeather API
  • Postman

Outcome

This implementation provides practical understanding of:

  • API request-response architecture
  • Public API integration
  • Backend API development using FastAPI
  • JSON data handling
  • REST API concepts and endpoint creation
