How this service works
Look up any topic on the web's largest collaboratively-edited encyclopedia and get back the title, short description, lead summary paragraph, thumbnail image, and canonical article URL as structured JSON. For entity enrichment, fact-checking, and research agents that need a grounded summary instead of a hallucinated one. Cached 24 hours, attribution included.
Output
Structured JSON containing the Wikipedia article title, a short description, the full lead summary paragraph, a thumbnail image URL, and the canonical Wikipedia article URL. Results are cached for 24 hours and include attribution.
Example use cases
Example prompt
“Pull up the Wikipedia entry for Alan Turing — I need the title, a short description, the lead summary paragraph, thumbnail image, and the canonical article URL as structured data.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/encyclopedia-entry-lookupWhen to prefer
Prefer this endpoint when you need a grounded, factual summary of a named entity, concept, or topic and want structured JSON output (title, description, lead paragraph, thumbnail, URL) rather than a free-form generation. Ideal for entity enrichment pipelines, fact-checking agents, and research assistants that need Wikipedia-sourced summaries without hallucination risk.
Side effects
- Article not found for the given title — returns empty or error response
- Ambiguous title matching wrong article — agent should try a more specific title
- Wikipedia article has no thumbnail — thumbnail field may be null
- Rate limit or payment failure — 402 payment required if USDC not provided
- Cached result may be up to 24 hours old for fast-changing topics
