Example prompt: Can you pull up a structured summary for Alan Turing — short description, lead paragraph, thumbnail, and source URL?

## When to prefer this

Use this endpoint when an agent needs quick, grounded, structured background on a person, place, or concept — especially when a concise lead paragraph and thumbnail are needed alongside a description. Prefer over raw web search when structured, encyclopedia-style output is required without hallucination risk.

## Known failure modes

- Topic title not found in knowledge base — returns empty or error response
- Ambiguous title matching multiple topics — may return unexpected article
- Network or payment authorization failure — no result returned
- Topic exists but has no thumbnail — thumbnail field may be null or missing

## How this service works

Pull a structured summary for any known topic — short description, lead paragraph, thumbnail, and source URL — from a continuously updated, community-maintained knowledge base. Accepts titles with spaces or underscores. Built for research agents and chatbots that need quick, grounded background on a person, place, or concept.

## Output

A structured object containing a short description of the topic, a lead paragraph of background information, a thumbnail image URL, and a link to the source article in the knowledge base.
