## 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-attention-article-title-search-40094c7b
```

Example prompt: Search Wikipedia for 'Elon Musk' and show me up to 5 matching article titles with their one-line descriptions so I can pick the right one.

## When to prefer this

Use this endpoint when you need to resolve a keyword or phrase to a specific Wikipedia article title, especially when the topic is ambiguous and multiple articles might match. It is ideal as a first step before fetching full article content, view statistics, or edit history from sibling endpoints. Prefer this over a general web search when you specifically need canonical Wikipedia article identifiers.

## Known failure modes

- Empty results if query matches no Wikipedia titles
- Degraded flag set to true if Wikimedia API is partially unavailable
- Invalid language code returns error or falls back to English
- Limit outside 1–15 range may be clamped or rejected
- Network timeout if Wikimedia API is slow

## How this service works

Search Wikipedia article titles by words: exact titles, one-line descriptions and thumbnails, to disambiguate a topic.

## Output

Returns a list of up to 15 matching Wikipedia article objects, each containing the article title, a URL-safe title key, a one-line description, and the matched title variant. Also includes the original query, source URL, language, and timestamp metadata. May include a summary, verdict, reasons, and disclaimer fields depending on the service response.
