`client.agent.research(AgentResearchParamsbody, RequestOptionsoptions?): ResearchEvent | Stream<ResearchEvent>`

**post** `/research`

Execute AI-powered research queries that search the web, analyze sources, and synthesize comprehensive answers. This endpoint **always streams** responses using Server-Sent Events (SSE).

**Streaming Response:**

- All responses are streamed using Server-Sent Events (`text/event-stream`)
- Real-time progress updates as research progresses through phases

**Research Modes:**

- `fast` - Quick answers with minimal web searches
- `balanced` - Standard research with multiple iterations (default)

**Use Cases:**

- Answering complex questions with cited sources
- Synthesizing information from multiple web sources
- Research reports on specific topics
- Fact-checking and verification tasks

### Parameters

    - `"balanced"`

  - `nocache?: boolean`

    Skip cache and force fresh research

### Returns

- `ResearchEvent`

  - `data?: unknown`

    Event payload data

  - `event?: "phase" | "progress" | "complete" | "error"`

    The event type: phase, progress, complete, or error
