Technical details
Endpoint
POSThttps://x402.onchainexpat.com/api/x402-tools/news/searchWhen to prefer
Use this endpoint when an agent needs to retrieve recent news articles from across the web for a specific keyword or topic, especially when you need metadata like author, source, image, and publish date alongside article links. Prefer over general web search when structured news article metadata is required.
Side effects
- Empty results if query matches no indexed articles
- Cached responses may return stale articles
- Result count may be less than requested limit if insufficient articles exist
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee
- Invalid sort_by value may cause error or default behavior
