## Endpoint

```
GET https://api.capture.page/v1/image?token={API_KEY}&url={TARGET_URL}

Authentication uses an API key + secret hash. See

official SDK.

```javascript
// Node.js SDK
import { Capture } from 'capture-node';

const capture = new Capture('your-api-key', 'your-api-secret');
const url = capture.buildImageUrl('https://example.com', {
  width: 1920,
  height: 1080,
  scaleFactor: 2,
  full: true,
});
```
