## How It Works
1. User enters text in the web interface
2. Frontend sends POST request to `/api/moderate`
3. Server calls the Profanity Filter API
4. API returns filtered text and flagged words
5. Frontend displays results with status
### The API Call
```javascript
const response = await fetch('https://api.apiverve.com/v1/profanityfilter', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'x-api-key': API_KEY
},
body: JSON.stringify({
text: 'Text to moderate',
mask: '*'
})
});
```
