How this service works
Wikipedia summary API - the plain-language summary of the best-matching Wikipedia article for a topic or query, in any language. Returns the article title, short description, summary extract, thumbnail image and canonical URL. A wikipedia / encyclopedia lookup for agents grounding answers on a topic. No match returns found:false. Data source: Wikipedia (CC BY-SA 4.0).
Output
Returns a JSON object with: the matched article title, a short description (subtitle), a prose summary extract, a thumbnail image URL, the canonical Wikipedia page URL, and a 'found' boolean (false if no matching article exists).
Example use cases
Ground AI answers on historical figures
“Look up the Wikipedia summary for 'Marie Curie' and give me her short description and the canonical Wikipedia link so I can cite it.”
Multilingual encyclopedia lookup
“Get me the Wikipedia summary for 'Ethereum' in Spanish — I need the article title, extract, and thumbnail image.”
Quick concept explanation for a report
“What does Wikipedia say about 'quantum entanglement'? I need a plain-language summary and the article URL to reference in my write-up.”
Technical details
Endpoint
POSThttps://search.openverbs.com/v1/wikipedia?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, citable, plain-language encyclopedia summary grounded in Wikipedia — especially for named entities, concepts, people, places, or events. Prefer this over web search when you want structured output (title, extract, thumbnail, URL) rather than a ranked list of links, and when factual grounding or citation is important. Use it over general LLM knowledge when you need a canonical source with a verifiable URL. Supports multilingual lookups via the lang parameter, making it ideal for international content pipelines.
Side effects
- No matching article found — returns found:false with no extract or thumbnail
- Ambiguous query may return a disambiguation page summary rather than the intended topic
- Language code not supported by Wikipedia edition — may fall back or return no result
- Query too vague returns an unrelated article
- Rate limit or payment failure returns an error without content
