Workflow
All AI generation tasks follow the same asynchronous workflow:
Submit a Task
Call POST /api/v1/task/submit, specify the model and parameters, and receive a taskId immediately.
Wait for Results
Retrieve results by polling GET /api/v1/task/:taskId or by setting up a Webhook callback.
Get Output
Once the task succeeds, result.urls contains the generated image or video URLs.File URLs are valid for 7 days from the time of generation. Please download and save files promptly to avoid link expiration.
