Endpoint
GEThttps://x402helper.xyz/89e509/news/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a synthesized, multi-source news brief on a specific topic rather than a single article or raw search results. It is well-suited for agents that need a quick, readable summary of recent coverage rather than raw links or headlines. Prefer it over generic web search when the goal is a coherent briefing rather than a list of URLs.
Side effects
- Missing required 'topic' parameter returns an error
- Invalid region locale may fall back to us-en default or error
- No articles found for a very narrow or obscure topic
- Timelimit filter 'd' (past day) may return few or no results for niche topics
- Upstream article fetch failures may reduce source count below requested max
