## 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 agent-data-tools-wikipedia-article-lookup-18a7faa6
```

Example prompt: Can you pull the Wikipedia article extract for 'Marie Curie' in English — I need the summary text, thumbnail image URL, and the proper attribution line?

## When to prefer this

Use this endpoint when you need fast, structured Wikipedia content (summary, description, thumbnail, attribution) for a known article title without scraping raw HTML. It is ideal for AI agents that need encyclopedic background information on a topic, person, place, or concept in a clean, licence-attributed format. Prefer it over generic web-scraping endpoints when you specifically want Wikipedia content, and over the full Wikipedia API when you only need the extract and metadata rather than full article markup.

## Known failure modes

- Article title not found — returns an error or empty result if the title doesn't match any Wikipedia article
- Language code not supported — non-existent or unsupported lang codes may yield no result
- Disambiguation pages — a title may resolve to a disambiguation page rather than a specific article
- Network/worker timeout — upstream Wikimedia API may be slow or unavailable
- Missing thumbnail — not all articles have an associated image, so thumbnail field may be absent

## How this service works

Short summary of a Wikipedia article in any language edition: title, one-paragraph extract, description, thumbnail and page URL. Use to ground an agent's answer in a quick, citable fact sheet.

## Output

Returns a JSON object with the article title, a plain-text extract (summary paragraph), a short description, the canonical Wikipedia URL, a thumbnail image URL, an attribution string, and the CC BY-SA 4.0 licence notice.
