Endpoint
POSThttps://x402.onchainexpat.com/api/x402-tools/wiki/summaryWhen to prefer
Use this endpoint when an agent needs a quick, factual, encyclopedic summary of a well-known topic, person, place, or concept. It is ideal when you want structured Wikipedia content without scraping the full page, and when a concise introduction-level overview is sufficient rather than a full article.
Side effects
- Article not found — ambiguous or misspelled topic title returns an error or empty result
- Disambiguation page — topic resolves to multiple articles with no single clear match
- Wikipedia API unavailable — upstream service error returns a failure response
- Payment failure — insufficient USDC balance prevents the call from completing
