# Get Image Task 상태

> Query image generation task status and results

* Query async image generation task execution status and results
* Real-time status updates and progress tracking
* Get generated images when task completes
* Multi-language support (zh/en/ko/ja)

All image generation tasks are executed asynchronously. After submitting a task, you need to query the status and results via the query endpoint.

## Authorizations

<ParamField header="Authorization" type="string" required>
  All endpoints require Bearer Token authentication

  Get your API Key:

  Visit the [API Key Management Page](https://toapis.com/console/token) to get your API Key

  Add it to the request header:

  ```
  Authorization: Bearer YOUR_API_KEY
  ```
</ParamField>

## Path 파라미터

<ParamField path="task_id" type="string" required>
  Task ID returned by the image generation API
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl --request GET \
    --url 'https://toapis.com/v1/images/generations/task_01KA040M0HP1GJWBJYZMKX1XS1' \

      return response.json()

  def wait_for_image(task_id, max_attempts=60, interval=3):
      for _ in range(max_attempts):

## Task 상태 Reference

| 상태            | 설명                                     | Is Final | Recommended Action                 |
| ------------- | -------------------------------------- | -------- | ---------------------------------- |
| `submitted`   | Task submitted, waiting for processing | ❌        | Wait 2-3 seconds, then query again |
| `in_progress` | Task is processing                     | ❌        | Wait 3-5 seconds, then query again |
| `completed`   | Task completed successfully            | ✅        | Get image from url field           |
| `failed`      | Task processing failed                 | ✅        | Check error info                   |

## Polling Strategy

```
Initial wait: 2 seconds
Polling interval: 3 seconds
Max wait: 120 seconds
Typical time: 5-30 seconds
```

### Python Polling Example

```python theme={null}
import time
import requests

def poll_image_task(task_id, api_key, max_wait=120):
    """Poll image generation task until completion or timeout"""
    start_time = time.time()
    interval = 3  # 3 second interval

    while time.time() - start_time < max_wait:
        response = requests.get(
            f'https://toapis.com/v1/images/generations/{task_id}',
            headers={'Authorization': f'Bearer {api_key}'}
        )
        data = response.json()

        if data['status'] == 'completed':
            return data['url']
        elif data['status'] == 'failed':
            raise Exception(f"Generation failed: {data['error']['message']}")

        time.sleep(interval)

    raise TimeoutError("Task timeout")
```

## Resource Expiration

<Warning>
  Generated image URLs are valid for **24 hours**

  * Please download and save images within the validity period
  * `expires_at` field indicates image expiration time (Unix timestamp)
  * Expired images cannot be accessed; to regenerate, submit a new task
</Warning>

## 오류 Codes

| HTTP Code | 오류 Type                    | 설명                         |
| --------- | -------------------------- | -------------------------- |
| 400       | `invalid_request`          | Invalid request parameters |
| 401       | `unauthorized`             | 인증 failed, check API Key   |
| 402       | `insufficient_quota`       | Insufficient balance       |
| 404       | `task_not_found`           | Task not found             |
| 422       | `content_policy_violation` | Content policy violation   |
