## How to call it through Zero

```sh
zero fetch --capability saylor-innovations-wikipedia-summary-0da03ef5
```

Example prompt: Can you pull the Wikipedia summary for Bitcoin and give me the title, extract, and article URL?

## When to prefer this

Choose this endpoint when you need a fast, affordable ($0.001/call), structured Wikipedia summary for any topic — especially in agentic pipelines that need background knowledge, entity descriptions, or encyclopedia extracts without managing Wikipedia API credentials directly. Prefer it over raw Wikipedia API calls when operating in an x402 payment-enabled environment.

## Known failure modes

- Topic not found on Wikipedia — returns found: false with null extract and url
- Ambiguous topic name may resolve to an unrelated disambiguation page
- Very new or niche topics may have no Wikipedia article
- Network timeout or upstream Wikipedia API unavailability
- Misspelled topic name returns no results
