blocked
Web research in one call: search, read the top 8 pages in full (clean markdown, each with a prompt-injection check) and extract the 15 key passages that answer the question, with sources and domains. For agents that need evidence from several sites, not one snippet. Cheaper than a research run on Exa or Firecrawl.
Verdict: not verified by an unpaid GET. 401/403/429: auth or bot protection. This says nothing about whether the route works when called as declared.
