## 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 sitesignal-wikipedia-summary-4b80bf72
```

Example prompt: Can you fetch me the Wikipedia summary for 'Marie Curie' in English — just the bounded intro excerpt with a source link back to the Wikipedia page?

## When to prefer this

Choose this endpoint when you need a fast, attribution-ready, bounded Wikipedia summary for a single well-known topic and want the result sourced directly from Wikimedia's REST API. It is ideal for enriching agent responses with encyclopedic background on people, companies, concepts, or events without scraping or parsing full HTML. Prefer it over general web search when you specifically want Wikipedia-sourced content with a verifiable link. It supports seven languages (en, de, es, fr, it, ja, pt), making it suitable for multilingual knowledge retrieval pipelines.

## Known failure modes

- Page title not found on Wikipedia returns a 404 or empty result
- Unsupported language code results in an error or fallback
- Ambiguous or redirected titles may return an unexpected article
- Wikimedia API rate limits or downtime propagate as upstream errors
- Very short or stub articles may return minimal summary content

## How this service works

Return a bounded source-linked summary for one public Wikipedia page through Wikimedia's REST API.

## Output

A bounded, source-linked plain-text summary of the requested Wikipedia article, including the page title, a concise introductory excerpt drawn from the Wikimedia REST API, and a reference URL back to the original Wikipedia page. The response is scoped to the summary section and does not return the full article body.
