# How to Start the Server

## The Problem

The "Not Found" error means the server is **not running**. You need to start it first.

## Solution: Start the Server

### Step 1: Open a PowerShell Terminal

Make sure you're in the project directory:
```powershell
cd C:\Users\tarun\IITMTdsPrj2
```

### Step 2: Set Environment Variables

```powershell
$env:QUIZ_SECRET = "EasyQuiz"
$env:OPENAI_API_KEY = "eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6IjI0ZjIwMDU3NTNAZHMuc3R1ZHkuaWl0bS5hYy5pbiJ9.eji7L5I62M9YHoeEKE8ao6eTw8dFjgDIMP9C3lOUXc4"
```

### Step 3: Start the Server

```powershell
python -m app.main
```

You should see:
```
INFO:     Started server process [...]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
```

**Keep this terminal open!** The server runs in this window.

### Step 4: Test in Another Terminal

Open a **NEW PowerShell window** and run:

```powershell
# Set variables again (in the new window)
$env:QUIZ_SECRET = "EasyQuiz"

# Test the API
$body = @{
    email = "24f2005753@ds.study.iitm.ac.in"
    secret = "EasyQuiz"
    url = "https://tds-llm-analysis.s-anand.net/demo"
} | ConvertTo-Json

Invoke-RestMethod -Uri "http://127.0.0.1:8000/demo" -Method POST -ContentType "application/json" -Body $body
```

## Quick Test Script

I've created a test script. After starting the server, run:

```powershell
.\test_server.ps1
```

This will test all endpoints and show you what's working.

## Troubleshooting

### "Module not found" error
```powershell
pip install -r requirements.txt
```

### "Port already in use" error
Another process is using port 8000. Either:
- Stop the other process
- Change the port: `$env:PORT = "8001"` then restart

### Server starts but endpoints don't work
- Make sure you're using the correct URL: `http://127.0.0.1:8000` or `http://localhost:8000`
- Check for errors in the server terminal
- Restart the server after code changes

## Summary

1. ✅ Start server: `python -m app.main` (keep terminal open)
2. ✅ Open new terminal for testing
3. ✅ Set variables in new terminal
4. ✅ Test API endpoints
