## 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-606e2b64 -d '<json body>'
```

Example prompt: Can you pull the Wikipedia summary for 'Marie Curie' — I need the lead paragraph, thumbnail, and the link to the article?

## When to prefer this

Use this endpoint when you need a quick, structured Wikipedia lookup (summary text + thumbnail + URL) without scraping Wikipedia directly or managing API credentials. Ideal for enriching entities, populating knowledge panels, or providing factual background in an agent pipeline at low cost ($0.002/call).

## Known failure modes

- Article title not found on Wikipedia — returns an error or empty result
- Ambiguous title matching multiple articles — may return the wrong article or disambiguation page
- Article exists but has no thumbnail — thumbnail field may be null or absent
- Rate limiting or payment failure via x402 protocol — request rejected before processing
