How this service works
A Wikipedia page summary by title or search words, in any language: title, short description, summary, page URL, thumbnail and Wikidata ID. For organisations, people and places, Wikidata facts: official website, inception, country, headquarters, date of birth and coordinates. Text is CC BY-SA 4.0 with attribution. Not found returns search suggestions.
Output
Returns a JSON object with the article title, a prose summary, a thumbnail image URL, the Wikipedia article URL, the Wikidata entity ID, license and attribution info, and structured Wikidata facts including country, headquarters, inception date, official website, and coordinates where available.
Example use cases
Company background research
“Pull up the Wikipedia entry for 'Stripe' — I want a quick summary, when it was founded, where it's headquartered, and a link to its website.”
Historical event fact lookup
“What does Wikipedia say about the 'Apollo 11' moon landing? Give me a summary and any key structured facts available.”
Multilingual Wikipedia lookup
“Look up 'Beethoven' on the French Wikipedia and give me a summary of his life and any structured facts like his birth date and nationality.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/wiki?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured summary of a well-known entity (company, person, place, event) backed by Wikipedia and Wikidata. It is ideal for enriching agent context with factual background, founding dates, headquarters, and official URLs without scraping HTML. Prefer it over raw web search when a reliable, encyclopedic, citation-ready answer is sufficient.
Side effects
- Article not found: 'found' field returns false with no summary or facts
- Ambiguous search query returns wrong article
- Wikidata facts partially null if entity lacks structured data
- Unsupported or invalid language code returns error or falls back to English
- Rate limit or upstream Wikipedia API outage returns error
