Path Parameters

​
id
string
required
The task ID returned from the initial image generation request.
If the create response included poll_url, prefer calling that exact URL for polling. Some image tasks may surface a poll_url under /v1/tasks/{id} instead of the image-specific status path.You can also poll public image task IDs such as ldtask_... at /v1/images/{id}. This compatibility alias uses the same authorization, ownership checks, billing headers, terminal snapshots, and response shape as /v1/images/generations/{id}.If the task no longer exists or is no longer available in the public task record, TokenLab returns async_task_not_found with the message Task not found or no longer available.

​
Response

​
created
integer
Unix timestamp of creation.
​
task_id
string
The task identifier.
​
status
string
Task status: pending, processing, completed, or failed.
​
data
array
Array of generated images (populated when status is completed).Each object contains:
  • url (string): URL of the generated image
  • revised_prompt (string): The prompt used for generation
​
error
string
Error message (only present when status is failed).

Polling Best Practices

Recommended polling interval: 3-5 seconds. Most image generation tasks complete within 30-120 seconds depending on the model and routed provider path.
import requests
import time

def poll_image_task(task_id, api_key, max_wait=300, interval=3):
    """Poll for image generation result with timeout."""
    url = f"https://api.tokenlab.sh/v1/tasks/{task_id}"
    headers = {"Authorization": f"Bearer {api_key}"}

    start_time = time.time()
    while time.time() - start_time < max_wait:
        response = requests.get(url, headers=headers)
        data = response.json()

        if data["status"] == "completed":
            return data["data"][0]["url"]
        elif data["status"] == "failed":
            raise Exception(data.get("error", "Generation failed"))

        time.sleep(interval)

    raise TimeoutError(f"Task {task_id} did not complete within {max_wait}s")

# Usage
image_url = poll_image_task("ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", "sk-your-api-key")
print(f"Generated image: {image_url}")
