Example use cases

Endpoint
GEThttps://api.x402node.dev/knowledge/wikipediaWhen to prefer
Use this endpoint when an agent needs to ground facts in encyclopedic sources, retrieve authoritative article summaries, or discover Wikipedia pages in a specific language. Prefer over general web search when you specifically need Wikipedia's structured, CC BY-SA licensed content with reliable article metadata like word count and page ID.
Side effects
- No results found for obscure or misspelled queries
- Invalid language code returns error or defaults to English
- Limit parameter out of range may be ignored or return error
- Network timeout for high-latency Wikipedia API calls
- Query too vague returns unrelated articles
