# Task
Using https://[REDACTED:TENANT].tavus.io/api-reference, complete the following task:

Using Tavus, build me a script that generates an AI avatar video:

1. List available avatars/replicas and voices (or use a stock/default avatar if available)
2. Create a video with the avatar speaking: "Hello! This is a ***** video from the [REDACTED:ORG] API leaderboard."
3. Poll for completion if the API is async (check status until the video is ready)
4. Print the result as JSON with fields: video_id, status, video_url (the URL where the video can be viewed or downloaded)

Note: Most video avatar APIs are async — you may need to poll the status endpoint until the video is ready. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
