## 🔧 Integration Examples

### Python
```python
import openai

client = openai.OpenAI(
base_url="https://cepheus-x.vercel.app/v1/",
api_key="sk-efghijkl5678mnopabcd1234efghijkl5678mnop"
)

response = client.chat.completions.create(
model="gpt-4o",
messages=[{
"role": "user",
"content": "Hello from Cepheus!"
}]
)

print(response.choices[0].message.content)
```

### JavaScript/TypeScript
```javascript
import OpenAI from 'openai';

const openai = new OpenAI({
baseURL: 'https://cepheus-x.vercel.app/v1/',
apiKey: 'sk-efghijkl5678mnopabcd1234efghijkl5678mnop',
dangerouslyAllowBrowser: true,
});

async function main() {
const response = await openai.chat.completions.create({
model: 'gpt-4o',
messages: [
{
role: 'user',
content: 'Hello from Cepheus!',
},
],
});

console.log(response.choices[0].message.content);
}
```

### cURL
```bash
curl https://cepheus-x.vercel.app/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer sk-efghijkl5678mnopabcd1234efghijkl5678mnop" \
-d '{
"model": "gpt-4o",
"messages": [
{
"role": "user",
"content": "Hello from Cepheus!"
}
]
}'
```

## 🛡️ Enterprise Features

### Hallucination Prevention
```python
def check_for_hallucination(response, facts):
hallucination_detected = False
explanation = ""

for fact in facts:
if fact["check_type"] == "should_contain" and fact["key"] not in response:
hallucination_detected = True
explanation += f"Response is missing key information: {fact['key']}\n"

return hallucination_detected, explanation
```
