## 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-summary-0f06c2a4
```

Example prompt: Can you pull the Wikipedia summary for Marie Curie — I want the title, short description, and the intro paragraph?

## When to prefer this

Use this endpoint when you need quick, structured factual background on a well-known person, place, company, or concept and want a ready-to-use summary without scraping a full web page. Prefer it over general web search when you specifically want Wikipedia's lead section with metadata like Wikidata ID, coordinates, and thumbnail. It supports multiple language editions, making it useful for multilingual pipelines. Choose alternatives if you need the full article body, revision history, or real-time information beyond what Wikipedia covers.

## Known failure modes

- No matching article found for the given topic — returns an empty or error response
- Ambiguous topic may resolve to an unexpected article (e.g. disambiguation pages)
- Language edition requested may not have an article for the topic — falls back or errors
- Rate limiting or service unavailability on the underlying Wikimedia API
- Topic string typos leading to no match

## How this service works

Lead summary of the Wikipedia article that best matches a topic, in any language edition: title, short description, summary paragraph, image, coordinates, Wikidata id and link. Use for quick factual background on a person, place, company or concept.

## Output

Returns a structured object containing the matched article's title, plain-language short description, lead summary paragraph, thumbnail image URL, geographic coordinates (if applicable), Wikidata entity ID, and a link to the full Wikipedia article. Content is drawn from the Wikipedia edition matching the requested language code.
