## 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 wikipedia-page-summary-api-4db5f833
```

Example prompt: Can you pull up the Wikipedia summary for Bitcoin — I need the title, short description, and a plain-text extract of the article.

## When to prefer this

Use this endpoint when you need a quick, structured overview of any well-known topic, person, place, or concept sourced from Wikipedia — especially when you need both a human-readable description and a plain-text extract in a single call. Prefer this over full web scraping when a concise Wikipedia-sourced summary is sufficient.

## Known failure modes

- Page not found (404) if the title doesn't match any Wikipedia article
- Disambiguation pages returned if the title is ambiguous
- Empty or missing thumbnail if the article has no image
- Capitalization or spacing issues in the page title causing lookup failure
- Rate limiting or payment failure (402) if credits are exhausted
