## 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-lookup-ade6fdf9
```

Example prompt: Can you pull up the Wikipedia summary for 'Quantum entanglement' — I need the title, one-line description, and the lead paragraph?

## When to prefer this

Use this endpoint when you need a concise, structured encyclopedia summary of any topic without scraping Wikipedia directly. Ideal for quick fact-lookup, knowledge enrichment, chatbot grounding, or populating structured data with human-readable descriptions. Prefer it over full web search when you specifically want the authoritative Wikipedia lead section in a specific language.

## Known failure modes

- Article not found for the given title returns a 404 or empty result
- Ambiguous or misspelled title may return an unrelated article
- Requested language edition may not have an article for the topic
- Title with special characters may need URL encoding
- Very new or obscure topics may lack a Wikipedia entry

## How this service works

Encyclopedia summary of a topic: title, one-line description, the lead paragraph as plain text, thumbnail and article link, in any language edition.

## Output

A JSON object containing the article's title, a one-line description (e.g. 'Binary-to-text encoding scheme'), the lead paragraph as plain text (extract), a thumbnail image URL if available, and the full Wikipedia article URL — all for the requested language edition.
