deep_research
Read-onlyDeep 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": "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.
Parameters
| Name | Type | Description |
|---|---|---|
| topic* | string | The research question or topic |
| queries | array | Optional explicit query list — overrides the default multi-angle sweep. |
