### 1️⃣ OpenAI Standard Format

**Node.js Environment (Safe)**

```typescript
const openAIRequest = XRequest('https://api.example-openai.com/v1/chat/completions', {
  headers: {
    Authorization: `Bearer ${process.env.OPENAI_API_KEY}`, // Node.js environment variable
  },
  params: {
    model: 'gpt-3.5-turbo',
    messages: [{ role: 'user', content: 'Hello' }],
    stream: true,
  },
});
```

**Frontend Environment (Using Proxy)**

```typescript
// ❌ Dangerous: Do not configure token directly in frontend
// const openAIRequest = XRequest('https://api.example-openai.com/v1/chat/completions', {
//   headers: {
//     'Authorization': 'Bearer sk-xxxxxxxx', // ❌ Will expose key
//   },
// });

// ✅ Safe: Through same-origin proxy
const openAIRequest = XRequest('/api/proxy/openai', {
  params: {
    model: 'gpt-3.5-turbo',
    messages: [{ role: 'user', content: 'Hello' }],
    stream: true,
  },
});
