How this service works
Public-web fact lookup (Wikipedia REST summary)
Output
Returns a Wikipedia REST summary object for the queried topic, including the article title, a short plain-text extract (typically 1-3 sentences), a longer description, and potentially a thumbnail image URL and page URL — giving the agent a concise, sourced factual snippet ready for use.
Example use cases
Quick biography lookup for research
“I'm writing a report — can you pull the Wikipedia summary for Marie Curie so I have a concise overview of her life and achievements?”
Entity background check for due diligence
“Before I take this meeting, can you look up BlackRock on Wikipedia and give me a quick summary of what the company does?”
Fact-check a concept for a presentation
“Can you grab the Wikipedia summary for the Treaty of Versailles? I want to make sure I have the basic facts right before my presentation.”

Endpoint
GEThttps://x402-lookup-seller.fly.dev/v1/lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.05 USDC), structured Wikipedia summary for a named entity, concept, or topic — especially within an x402-payment-enabled agent pipeline. Prefer it over generic search engines when you specifically want encyclopedic, sourced fact snippets rather than web search results or LLM-generated answers.

- Ambiguous topic names may resolve to the wrong Wikipedia article
- Very new or obscure topics may lack a Wikipedia page
- Rate limits or upstream Wikipedia API downtime may cause failures
