How this service works
Use this when you need a fast cited answer, not deep research: one live web search, relevance-ranked sources, snippet-level digest with 3-6 cited key points in seconds. No API key, no signup — x402 per-call payment only. For full-page depth use the $0.05 Research Brief on the same origin.
Output
A snippet-level digest containing 3-6 cited key points derived from one live web search, with relevance-ranked sources and brief excerpts supporting each finding, returned in seconds.
Example use cases
Breaking news fact-check with sources
“What's happened with the SpaceX Starship program in the last 7 days? Give me up to 6 cited key points from live web results.”
Market trend snapshot for investor
“Give me a quick cited summary of recent Bitcoin ETF inflows — pull from the last 30 days and give me 4 key findings with sources.”
Competitive intelligence on a product launch
“What are the key highlights about Apple's Vision Pro sales performance? I want 5 cited points from recent web sources, nothing older than 90 days.”

Choose this endpoint when you need a fast, cited answer with live web data and don't require deep full-page analysis. It's ideal for quick fact-checks, current events summaries, or any query where 3-6 key points with sources are sufficient. Prefer the $0.05 Research Brief sibling on the same origin when you need full-page depth and more thorough source reading. This endpoint is best for speed and cost-efficiency at $0.01 per call with no API key or signup required.
Side effects
- Topic string under 10 characters or over 200 characters returns a validation error
- Payment not provided or x402 handshake fails — endpoint returns 402 Payment Required
- Live web search returns no relevant results for obscure or very niche topics
- recency_days set to 7 for very recent events that haven't been indexed yet — may return sparse results
- max_findings out of range (below 3 or above 6) returns a validation error
