## How to call it through Zero

```sh
zero fetch --capability wikipedia-article-summary-lookup-fe5fea86
```

Example prompt: Can you pull up the Wikipedia summary for Guadeloupe in French — I need the title, description, lead paragraph, and thumbnail if it has one?

## When to prefer this

Choose this endpoint when you need a fast, structured Wikipedia summary for a known topic in a specific language without scraping Wikipedia directly. It is ideal for enriching entity data, providing quick reference overviews, or pulling multilingual Wikipedia content into an agent workflow. Prefer it over raw web scraping when you want clean, structured output (title, description, extract, URL, thumbnail, coordinates) with minimal overhead and no HTML parsing required.

## Known failure modes

- Title not found in the requested language edition — falls back to best matching title which may not be exact
- Language code not supported or misspelled returns an error
- Ambiguous titles may resolve to disambiguation pages rather than the intended article
- No thumbnail or coordinates returned for subjects that don't have them on Wikipedia
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

The plain-language summary of a Wikipedia article in any language edition: title, short description, lead extract, canonical URL, thumbnail and coordinates when the subject has them. Falls back to the best matching title. Query: ?title=Guadeloupe&lang=fr

## Output

A JSON object containing the article title, a short description, the lead extract (plain-language intro paragraph), the canonical Wikipedia URL, a thumbnail image URL when available, and geographic coordinates when the subject is a location. Falls back to the best title match if the exact title is not found.
