## 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 2s-io-82777bf9
```

Example prompt: Can you grab me the Wikipedia summary for 'Marie Curie' in English — I need the plain text extract, the lead image, and the last-modified date?

## When to prefer this

Use this endpoint when you need a quick, structured Wikipedia summary with rich metadata (word count, license, attribution, lead image) for any of 30 languages, especially when you need attribution-ready content under CC BY-SA 4.0. Prefer it over raw Wikipedia scraping or the full Wikipedia API when you want a clean, normalized response with a consistent schema.

## Known failure modes

- Article not found for the given title — Wikipedia returns 404 and the endpoint likely surfaces a not-found error
- Ambiguous or redirected title — may return a different article than intended if disambiguation is needed
- Unsupported language code — request fails if lang value is not in the 30-item enum
- Title too long (>300 chars) or empty — schema validation error
- Wikipedia upstream rate-limiting or downtime — upstream 5xx propagated
