## 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`):

zero fetch --capability the-stall-wikipedia-intelligence-x402-d49e7881
```

Example prompt: Search Wikipedia for 'transformer neural network' and give me the top 3 articles in English.

## When to prefer this

Use this endpoint when an agent needs factual, encyclopedic background information about a person, concept, technology, event, or entity and Wikipedia is a suitable source. Prefer it over web search endpoints when structured article-level information is needed rather than live news or real-time data. It is especially useful for grounding responses with well-sourced reference content without needing API keys.

## Known failure modes

- No matching Wikipedia article found for the given query
- Invalid language code returns an error or falls back to English
- Exact=true with a misspelled or non-existent page title returns no results
- Limit exceeds maximum of 8, causing a validation error
- Payment failure or insufficient USDC balance prevents the call

## How this service works

Wikipedia article lookup and search. Given a search query, returns the top matching Wikipedia articles with title, plain-text extract (~800 chars), description, thumbnail URL, page URL, and last-modified date. Use for rapid factual lookup, entity enrichment, concept explanation, or pre-flight research on any topic. No API key required.

## Output

Returns one or more Wikipedia articles matching the query, including titles and article content/summaries. In exact mode, returns a single article for the given page title directly. In search mode, returns up to 8 ranked matching articles.
