How this service works
Encyclopedia summary API: the lead summary of any English-language encyclopedia article — title, one-line description, extract paragraph, thumbnail, and canonical URL — as JSON. For entity enrichment, fact grounding, and knowledge agents. CC BY-SA content with attribution included.
Output
A JSON object containing the article title, a one-line description, an introductory extract paragraph, a thumbnail image URL, and the canonical encyclopedia URL for the queried entity. Content is CC BY-SA licensed with attribution included.
Example use cases
Example prompt
“Can you look up a quick encyclopedia summary for 'Marie Curie' — I need her one-line description, a short extract, and the canonical article URL?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/knowledge-lookupWhen to prefer
Use this endpoint when you need a structured, machine-readable encyclopedia summary for a named entity — person, place, concept, or event — especially for entity enrichment pipelines, knowledge graph population, or fact grounding. Prefer it over raw web search when you want clean JSON with a canonical description, extract, and thumbnail rather than unstructured HTML. The $0.003 per-call pricing makes it cost-effective for moderate-volume enrichment tasks.
Side effects
- Article title not found — returns an error or empty result if the title does not match any encyclopedia article
- Disambiguation required — a vague title (e.g. 'Mercury') may return the wrong article
- Non-English titles — endpoint covers English-language articles only, foreign-language titles may fail
- Payment failure — insufficient USDC balance or x402 payment handshake fails
- Network timeout — upstream Wikimedia API latency causes delayed or failed response
