| Key       | Value            |
|-----------|-----------------|
| `x-api-key` | your_api_key    |
| `Content-Type` | application/json |

{
    "expiresIn": "100",
    "requestID": "xxxxx"
}
```
### Response:
```json

```




## Browser Support

✅ Chrome (latest)  
✅ Firefox (latest)  
✅ Safari (latest)  
✅ Edge (latest)

---

## Requirements

- WebGL-enabled browser
- JavaScript enabled
- Minimum screen resolution: 800x600

---

## Best Practices

- Always initialize the SDK with a valid API key
- Implement error handling for load failures
- Clean up resources when removing the avatar
- Optimize container size for better performance
- Test across different browsers and devices

---

## Examples

### Basic Implementation

```javascript
    import {SceneCanvas, Character} from 'ultron-ai-sdk';        
        
    let sceneCanvas
    let character
    
    const init = async() => {
        sceneCanvas = new SceneCanvas('target-html-element')
        const initializationSetting= {
            avatarId: "AVATAR_ID/REQUEST_ID",
            config:{
                sessionId: "xxxxxxx-xxxx-xxxx-xxxx-xxxxxxx"
            },
            options:{
                alwaysListen: false // For Push to talk conversation
            }
        }
        await sceneCanvas.init(initializationSetting)
        character = sceneCanvas.character
                    
    }
    init()
```

---

### Chat with character using AI

```javascript
// once you have the "character" object from sceneCanvas after init() you can use it to chat

character.chat("your text query to AI")

//This will generate a response from AI as per Avatar backstory and character will speak the response


```

### Make the character say

```javascript

character.say("your text that character will speak")

// This will simply make the character speak the text you provide

```

### Switch camera

```javascript
//Switch camera to potrait (closer to face)

sceneCanvas.switchCameraToPotrait()

//Switch camera to normal position (full body view)

sceneCanvas.switchCameraToNormal()



```
