# Get task status

> Lightweight status check. Use this for polling — it does not load the task feed
and is the cheapest endpoint per request.




## OpenAPI

````yaml GET /api/v1/tasks/{task_id}
openapi: 3.1.0
info:
  title: Nanonets Agents Platform — Public API
  version: 1.0.0
  summary: >-
    Programmatically run AI agents, send follow-up messages, fetch results, and
    update agent prompts.
  description: >
    The Nanonets Agents Platform Public API lets you trigger agents, stream task
    progress,

    and integrate agent outputs into your own systems.


    ## Authentication


    All requests must include a workspace API key as a Bearer token:


    ```

    Authorization: Bearer YOUR_API_KEY

    ```


    Workspace API keys are minted from the web app under **Settings → API
    Keys**. Each key

    is scoped to a single workspace; requests against agents or tasks outside
    that workspace

    return `403`.


    ## Lifecycle


    A typical integration is three calls:


    1. `POST /v1/agents/{agent_id}/run` — start a task. Returns a `task_id`
    immediately.

    2. Poll `GET /v1/tasks/{task_id}` until `status` is a terminal value
    (`completed`,
       `failed`, or `stopped`), **or** wait until it reaches `waiting_for_input` to
       respond with `POST /v1/tasks/{task_id}/message`.
    3. `GET /v1/tasks/{task_id}/summary` for the final answer, or `/result` for
    the full
       reasoning trace.

    ## Errors


    Every error response is `{"error": "<human-readable message>"}`. The HTTP
    status

    indicates the class:


    | Status | Meaning |

    |--------|---------|

    | 400 | Malformed request (bad UUID, missing required field, file too large)
    |

    | 401 | Missing or invalid API key |

    | 403 | API key is valid but the agent/task belongs to a different workspace
    |

    | 404 | Agent or task not found |

    | 500 | Server error — safe to retry with backoff |
