## 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 suverse-wikipedia-article-summary-a1af714c -d '<json body>'
```

Example prompt: Can you pull the Wikipedia summary for 'Nikola Tesla' — I need the short description, extract, and canonical URL to include in my report?

## When to prefer this

Choose this endpoint when you need structured encyclopedic context for a specific named entity or topic — particularly when you already know the Wikipedia article title. It is preferable to a general web search when you need a clean, structured response (extract, thumbnail, URL) rather than raw web results, and when you want authoritative, citation-ready content. It complements the sibling random-Wikipedia endpoint when you need a targeted lookup rather than random discovery.

## Known failure modes

- Article title not found — Wikipedia returns a 404-style missing page response
- Disambiguation page returned when title is ambiguous (e.g. 'Mercury' could be planet, element, or god)
- Empty extract returned for stub or redirect articles
- Rate limiting or upstream Wikipedia API downtime causing 503 errors
- Payment failure or insufficient USDC balance causing x402 rejection

## How this service works
