## How It Works
1. User enters a username
2. Frontend sends GET request to `/api/check`
3. Server calls the Username Profanity API
4. API analyzes the username
5. Frontend displays safe/profane result
### The API Call
```javascript
const response = await fetch(`https://api.apiverve.com/v1/usernameprofanity?username=${username}`, {
method: 'GET',
headers: {
'x-api-key': API_KEY
}
});
```

}
```
