deep_research

Read-only

Deep multi-angle research: several search queries, deduped sources, top pages fetched — returns a structured digest with citations.

When to use: Use for substantial research questions where one search isn't enough — it sweeps multiple query angles and returns sources + page excerpts to synthesize WITH CITATIONS. For a quick lookup use web_search or research_brief instead.

Example

The call

tool call
{
  "tool": "deep_research",
  "arguments": {
    "topic": "What changed in Python 3.14's free-threaded build?",
    "queries": [
      "python 3.14 free threading"
    ]
  }
}

Needs a search API key: web_search_provider='brave', 'serper' or 'tavily' with its key. DuckDuckGo's keyless results page now answers automated requests with a bot check, which the tool reports as an error

So it isn't run here, and no output is shown: nothing on this page is made up.
