Capstone: JSON ping web server

Requirements

Deliver a Python service using FastAPI and Uvicorn that:

Optional extras (only if assigned): GET / with a welcome JSON, POST /alive with a JSON body, health checks, or HTTPX integration tests.

Example core

Your implementation can look like this:

from fastapi import FastAPI

app = FastAPI()

@app.get("/ping")
def ping():
    return {"message": "pong"}

Start with:

uvicorn your_module:app --host 0.0.0.0 --port 8000

Replace your_module with your actual module path.

Checklist

• GET /ping returns Content-Type: application/json and body {"message":"pong"} (spacing may vary; keys/values must match).
• Virtual environment created and FastAPI / Uvicorn / dependencies installed per Virtual environments and packages.
• Dependencies listed in requirements.txt / pyproject.toml per template.
• README explains how to create venv, install, and run.
• Committed and pushed to main for final review (solution code only—not personal test_*.py files; see Testing with pytest).

Congratulations—you now have a minimal JSON API foundation without relying on terminal UI frameworks.
