## 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 anokha-web-tools-wikipedia-lookup-a4a287f3
```

Example prompt: Can you look up the Wikipedia summary for 'quantum entanglement' and give me the title, description, and a short extract?

## When to prefer this

Choose this endpoint when you need a quick, structured Wikipedia summary (URL, title, extract, description) without scraping the full page. It is ideal for agents that need encyclopedic background information on a topic with minimal latency and no API key setup, paid per-call via USDC on Base (x402). Prefer it over full web-to-Markdown conversion when only a Wikipedia snippet is needed.

## Known failure modes

- Query matches no Wikipedia article — empty or null response
- Ambiguous query returns wrong article (disambiguation page)
- Requested language not supported or article not available in that language
- Network timeout or upstream Wikipedia API failure
- Malformed query parameter causes validation error
