## 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-article-summary-api-x402-forgemesh-io-fea149ce -d '<json body>'
```

Example prompt: Can you pull the Wikipedia summary for Marie Curie — I need the title, short description, lead paragraph, and the canonical article URL?

## When to prefer this

Use this endpoint when you need quick, structured, factual summaries about named entities — people, places, concepts, organizations — from Wikipedia, especially for entity enrichment, fact grounding, or research agent pipelines. Prefer this over a general web search when you want clean, CC BY-SA 4.0 licensed structured data with a stable schema.

## Known failure modes

- Missing or misspelled title returns an unpaid 404 (page not found)
- Ambiguous title may resolve to the wrong article or disambiguation page
- Non-English Wikipedia articles are not supported
- Thumbnail may be absent for articles without images
- Cached response may be up to 24 hours stale

## How this service works

Knowledge summary API: the lead summary of any English Wikipedia article — title, short description, extract paragraph, thumbnail, and canonical URL — as structured JSON. Titles accept spaces or underscores; missing pages return an unpaid 404. Use for entity enrichment, fact grounding, and research agents. CC BY-SA 4.0 with attribution in every response. Cached 24 hours.

## Output

A structured JSON object containing the Wikipedia article's title, a short description, a plain-text extract (lead paragraph), a thumbnail image URL, and the canonical Wikipedia URL. If the title is not found, a 402/404 response is returned.
