How this service works
Encyclopedic grounding in one call: Wikipedia search plus the full summary of the best match — extract, short description, canonical URL, thumbnail — in any of 300+ language editions. Official Wikimedia REST APIs, CC BY-SA attribution included. The cheapest way for an agent to ground an entity before reasoning about it.
Output
A JSON object containing the query, language edition, a list of matching article titles with keys and URLs, the top match's full plain-text extract, short description, thumbnail URL, canonical Wikipedia URL, last-modified timestamp, and a CC BY-SA attribution string ready to include when republishing.
Example use cases
Entity grounding before reasoning
“Before you answer my question about the European Central Bank, look it up on English Wikipedia and give me the summary extract and canonical URL so we have solid context to work from.”
Multilingual Wikipedia lookup for localization
“Find the Wikipedia article for 'Kyoto Protocol' in the French edition and return the extract, description, and article URL — I need it in French for a report I'm writing.”
Quick person or organization fact-check
“Can you search Wikipedia for 'Ada Lovelace', return the top match's full summary, thumbnail, and short description, and tell me when the article was last updated?”
Technical details
Endpoint
POSThttps://agentbit.app/v1/knowledge/wikiWhen to prefer
Choose this endpoint when an agent needs fast, cheap encyclopedic grounding for a named entity — a person, place, concept, or technology — before reasoning about it, especially when you want multilingual coverage or need the canonical URL, thumbnail, and attribution in a single round-trip. It is cheaper and more structured than a general web search for entity lookups, and more reliable than scraping Wikipedia directly. Prefer it over generic search endpoints when the subject is well-known enough to have a Wikipedia article and you need structured metadata (description, thumbnail, last-modified) rather than open-web results.
Side effects
- No Wikipedia article found for the query — returns an empty matches array and no top_summary
- Query string too short or too long (outside 2-300 characters) — validation error
- Unsupported or malformed language code — may fall back to English or return an error
- Limit value outside 1-10 range — validation error
- Wikimedia API upstream timeout — HTTP 502 or 504 response
- Rate limit exceeded — HTTP 429 response
