# Architecture Overview

Our platform is engineered for high throughput, predictable latencies, and distributed fault tolerance.

> **Info: Zero Downtime Deployments**
> All endpoints operate across multiple geographically distributed availability zones.

## Implementation Steps

**Generate Credentials**

Obtain your API Key from the portal settings and configure it in your environment variables.

**Configure Webhooks**

Register a secure HTTPS callback URL to receive real-time event notifications.

**Test Endpoints in Sandbox**

Validate schema payloads against the sandbox environment before going live.

## Code Examples

**JavaScript**

```javascript
const res = await fetch('https://api.example.com/v1/items', {
  headers: { Authorization: 'Bearer YOUR_TOKEN' }
});
const items = await res.json();
```

**Python**

```python
import requests

res = requests.get('https://api.example.com/v1/items', headers={
    'Authorization': 'Bearer YOUR_TOKEN'
})
items = res.json()
```

**cURL**

```bash
curl -H "Authorization: Bearer YOUR_TOKEN" https://api.example.com/v1/items
```
