## 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 socialfetch-youtube-hashtag-search-9355d95a
```

Example prompt: Can you search YouTube for videos tagged with #AIart and show me the results — include both regular videos and Shorts?

## When to prefer this

Use this endpoint when you need to discover YouTube videos associated with a specific hashtag, especially for trend monitoring, content research, or social listening on YouTube. Prefer this over generic YouTube search APIs when hashtag-based filtering is the primary axis. Use the 'shorts' type filter when you specifically want short-form content.

## Known failure modes

- Invalid or empty hashtag returns an error
- Expired or invalid pagination cursor returns an error or empty results
- Rate limiting or payment failure returns 402 or 429 status
- Hashtag with no YouTube results returns an empty list
- Overly long hashtag (exceeding 256 chars) is rejected with a validation error

## How this service works
