## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability basebuilder2-youtube-downloader-f1202d17 -d '<json body>'
```

Example prompt: Can you download this YouTube video for me — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and give me a direct download link for the mp4?

## When to prefer this

Use this endpoint when an agent needs to programmatically download or retrieve a YouTube video file given a URL, especially within a paid x402 micropayment-enabled workflow. Prefer this over manual browser downloads or other scraping tools when integrating into an automated pipeline that already handles USDC micropayments.

## Known failure modes

- Invalid or malformed YouTube URL returns an error
- Private or age-restricted videos may be inaccessible
- Video removed from YouTube returns not found error
- Rate limiting or service timeout for large video files
- Unsupported video format or quality tier requested
