## How to call it through Zero

## When to prefer this

Choose this endpoint when you need a quick, authoritative, source-linked summary of a well-known topic that has a Wikipedia page, especially when you need multilingual support across en/de/es/fr/it/ja/pt. It is ideal for enriching agent responses with factual background context without needing a full web search. Prefer alternatives if you need real-time information, niche topics without Wikipedia coverage, or languages outside the supported set.

## Known failure modes

- Wikipedia page not found for the given title — returns 404 or empty result
- Ambiguous title matching multiple Wikipedia disambiguation pages — may return wrong article or error
- Unsupported language code provided — only en, de, es, fr, it, ja, pt are accepted
- Title exceeds 200 character limit — request rejected by schema validation
- Wikimedia REST API rate limiting or temporary unavailability — upstream timeout or 503 error
- Cloudflare tunnel instability causing intermittent connection failures

## How this service works
