## 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 ambolt-wikipedia-summary-3352652b
```

Example prompt: Can you grab the Wikipedia summary for 'Copenhagen' in English and give me the intro paragraph along with the article URL?

## When to prefer this

Choose this endpoint when you need a fast, attributed, structured Wikipedia summary for a known entity or topic title — especially when you require CC BY-SA attribution metadata, the last-edited timestamp, or multilingual support. It is preferable to scraping Wikipedia directly (no HTML parsing needed) and over general web search when the user specifically wants encyclopedic, crowd-sourced factual content rather than current news or opinionated sources.

## Known failure modes

- Article not found: 'found' returns false if the title does not match any Wikipedia article
- Disambiguation page: 'disambiguation' flag is true when the title maps to a disambiguation page rather than a specific article, requiring a more specific title
- Invalid language code: request fails or falls back to English if the lang parameter does not match a valid Wikipedia language code
- Title too long: rejected if title exceeds 200 characters
- Network or upstream timeout: Wikipedia API unavailable

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

Returns a JSON object containing the article title, a plain-text extract (intro paragraph), a short description, the Wikipedia URL, the language code, the last-edited timestamp, a fetch timestamp, CC BY-SA 4.0 attribution text, a flag indicating whether the article is a disambiguation page, and a 'found' boolean indicating whether the article exists.
