​
Path Parameters

​
id
string
required
The task ID returned from the create video request. Treat id and task_id as the same async identity.
If a create response returns poll_url, call that exact URL. When it points to /v1/tasks/{id}, treat that as the canonical fixed status endpoint.If the task no longer exists or can no longer be resolved through the public async-task contract, LemonData returns async_task_not_found with the message Task not found or no longer available.

​
Response

​
id
string
Canonical async task identifier.
​
task_id
string
Async task identifier alias.
​
poll_url
string
Preferred polling URL when the create response supplies one.
​
billing_transaction_id
string
LemonData billing transaction ID when settlement already completed. This is the dashboard/accounting transaction identifier and is separate from the async id / task_id.
​
status
string
Task status: pending, processing, completed, failed.
​
progress
number
Progress percentage (0-100).
​
video_url
string
URL of the generated video (when completed).
​
video
object
Single video payload with url, duration, width, and height when available.
​
videos
array
Multiple video payloads when the upstream returns more than one output.
​
error
string
Error message (if failed).
​
created
integer
Creation timestamp.
​
updated
integer
Last update timestamp.
​
model
string
Model used for the task.
curl "https://api.lemondata.cc/v1/tasks/ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" \
  -H "Authorization: Bearer sk-your-api-key"

Polling Best Practices

  • Poll every 5-10 seconds
  • Implement exponential backoff for long tasks
  • Set a maximum timeout (e.g., 10 minutes)
  • Handle failed status gracefully
import time

def wait_for_video(task_id, max_wait=600, interval=5):
    """Wait for video with timeout."""
    start = time.time()

    while time.time() - start < max_wait:
        response = requests.get(
            f"https://api.lemondata.cc/v1/tasks/{task_id}",
            headers={"Authorization": "Bearer sk-your-api-key"}
        )
        data = response.json()

        if data["status"] == "completed":
            return data["video_url"]
        elif data["status"] == "failed":
            raise Exception(data.get("error", "Video generation failed"))

        time.sleep(interval)

    raise TimeoutError("Video generation timed out")
