## 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-search-api-9eef4e2c
```

Example prompt: Search Wikipedia for 'stablecoin' and give me the top 3 results in English — I want titles, descriptions, and excerpts.

## When to prefer this

Choose this endpoint when you need structured Wikipedia search results (titles, descriptions, excerpts) in clean JSON format with predictable pricing at $0.001 per call, especially in agentic workflows that need factual background or entity lookups without scraping Wikimedia directly. Prefer over raw Wikimedia API when you need clean, ready-for-LLM output and want a simple, metered REST interface.

## Known failure modes

- Missing required query parameter 'q' returns a 400 error
- Invalid language code returns no results or an error
- Limit outside the 1–20 range may be rejected or clamped
- Obscure queries may return zero matching articles
- Payment failure (x402) if USDC balance is insufficient

## Output
