How this service works
Search English Wikipedia: top articles for a query with title, link, a cleaned snippet, word count and last edit.
Output
A JSON object containing the query string, a source label ('Wikipedia'), total hit count, and a results array where each item includes article title, URL, a cleaned text snippet, word count, and last-edit timestamp. Also includes an 'asOf' timestamp and optional degraded/disclaimer fields.
Example use cases
Background research on a historical event
“Search Wikipedia for 'Battle of Stalingrad' and return the top 5 results with titles, links, snippets, and when they were last edited.”
Quick fact-check on a scientific concept
“Can you look up 'CRISPR gene editing' on Wikipedia and show me the top 3 articles with their descriptions and how many words each one has?”
Exploring a person or organization
“Search Wikipedia for 'Marie Curie' and give me the most relevant articles — I want the titles, URLs, and a short snippet for each one.”

Endpoint
GEThttps://open-search.x402tookit.com/search-encyclopedia?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need encyclopedic, factual background information about well-known topics, people, places, or concepts from English Wikipedia, with metadata like word count and freshness. Prefer it over the sibling multi-source endpoint when you specifically want Wikipedia results only, not a blend of Hacker News, Crossref, or Wikidata. Prefer it over general web search when you need reliable, structured encyclopedia-style content rather than arbitrary web pages.
Side effects
- Query longer than 200 characters returns a validation error
- No Wikipedia articles found for obscure or misspelled query returns empty results array
- Limit parameter outside 1–10 range may be rejected or clamped
- Service degraded flag set if Wikipedia upstream is slow or partially unavailable
- Network timeout if Wikipedia API is unresponsive
