How this service works
Get a Wikipedia article summary by exact title. Returns extract (lead paragraph), description, thumbnail, originalimage, content URLs (desktop/mobile/edit), and wikibase_item. Use ?title=Albert_Einstein plus optional and lang=en. Built for AI agents doing literature review, biography lookup, and grounded RAG. Accepts payment on Base or Solana — either network works.
Output
Returns a JSON object containing the article extract (lead paragraph text), a short description, thumbnail image metadata, original image metadata, content URLs for desktop/mobile/edit views, and the wikibase_item identifier for the queried Wikipedia title.
Example use cases
Biography lookup for historical figure
“Hey, can you grab the Wikipedia summary for 'Nikola Tesla'? I need the lead paragraph and description to give my agent some grounded background before it writes a biography section.”
Concept background for RAG pipeline
“I'm building a RAG-powered Q&A bot and need grounded context on 'Quantum entanglement' — can you pull the Wikipedia extract, thumbnail, and content URLs for that topic so I can feed it into my pipeline?”
Entity metadata for knowledge base
“Can you look up 'World Health Organization' on Wikipedia and get me the description, wikibase item ID, and thumbnail? I want to enrich my knowledge base with verified metadata for this entity.”
Technical details
Endpoint
GEThttps://api.x402node.dev/knowledge/wikipedia-pageWhen to prefer
Use this endpoint when an AI agent needs grounded, encyclopedic context about a well-known entity, person, concept, or event by exact Wikipedia title — especially for RAG pipelines, biography lookups, or literature review tasks where a concise lead paragraph plus metadata is sufficient and real-time web scraping is not desired.
Side effects
- Article title not found on Wikipedia returns a 404 or empty result
- Ambiguous or redirected titles may return unexpected article content
- Non-English language codes may yield no result if article doesn't exist in that language
- Special characters or spaces in title not URL-encoded correctly may cause lookup failure
- Payment failure (insufficient USDC balance) results in 402 error before query is executed
