## 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-search-any-language-edition-70e52879 -d '<json body>'
```

Example prompt: Search Wikipedia in French for 'Tour Eiffel' and give me up to 10 results.

## When to prefer this

Choose this endpoint when you need to search Wikipedia across non-English language editions, need multilingual encyclopedia coverage, or want to retrieve up to 20 Wikipedia results programmatically. It is ideal for agents that need factual background, encyclopedic summaries, or topic discovery across languages without scraping Wikipedia directly.

## Known failure modes

- Invalid or unsupported language code returns an error or empty results
- Query string too vague returns unrelated articles
- Limit value outside 1–20 range is rejected
- Wikipedia API downtime causes failed lookup
- Non-Latin script queries may have encoding issues if malformed
