How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
Returns a JSON object containing the canonical Wikipedia article URL, the article title, and a plain-text extract (introductory summary paragraph) for the requested topic.
Example use cases
Quick concept briefing for a report
“I'm writing about proof-of-work consensus — can you grab the Wikipedia summary for 'Proof of work' so I have a solid one-paragraph definition to start from?”
Entity enrichment in a research pipeline
“I have a list of company names from a dataset — can you fetch the Wikipedia summary for 'Anthropic' so I can understand what kind of company it is before I process the rest?”
Chatbot factual grounding
“My assistant needs a reliable background blurb on the Eiffel Tower — can you get the Wikipedia extract for it so the response is factually grounded?”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/wiki/summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, factual encyclopedic summary of a well-known topic without setting up an API key or subscription. Ideal for agents doing one-off or low-volume lookups where per-call micropayment pricing is more economical than a monthly plan. Prefer over raw Wikipedia API calls when you want a clean, normalized response with no setup overhead.
Side effects
- Topic not found on Wikipedia — may return empty extract or 404-equivalent
- Ambiguous topic resolves to wrong Wikipedia article
- Wikipedia API temporarily unavailable — timeout or upstream error
- Payment failure via x402 — call not executed if micropayment is rejected
