Parallel Deep Research - Cited Reports With the Task API
========================================================

The Task API runs deep, multi-step research and returns an answer with a
"basis": the citations and confidence behind the findings. That is the
difference between an answer and an answer you can verify.

The agent calls create_task() to launch the research, then get_task_result()
to retrieve the report plus its sources.

Processors trade depth for time:
- "base"  - fast, good for most questions (seconds to a few minutes)
- "pro"   - deeper, and required for the "auto" output schema
- "ultra" - maximum depth (can run many minutes)

Prerequisites:
- pip install parallel-web
- export PARALLEL_API_KEY=<your-api-key>

## Run the Example

<Steps>
  <Snippet file="create-venv-step.mdx" />

  <Step title="Install dependencies">
    ```bash theme={null}
    uv pip install -U agno openai parallel-web
    ```
  </Step>

  <Step title="Export your API keys">
    <CodeGroup>
      ```bash Mac/Linux theme={null}
      export OPENAI_API_KEY="your_openai_api_key_here"
      export PARALLEL_API_KEY="your_parallel_api_key_here"
      ```

      ```bash Windows theme={null}
      $Env:OPENAI_API_KEY="your_openai_api_key_here"
      $Env:PARALLEL_API_KEY="your_parallel_api_key_here"
      ```
    </CodeGroup>
  </Step>

  <Step title="Run the example">
    Save the code above as `deep_research.py`, then run:

    ```bash theme={null}
    python deep_research.py
    ```
  </Step>
