Response Parameters

Parameter	Type	Description
`success`	boolean	Whether the request completed successfully.
`data.task_id`	string	Task ID used to query task status and results.
`data.model`	string	Model name used for the task.
`data.status`	string	Current status value returned by the API. Generation task endpoints use normalized values such as `pending`, `processing`, `completed`, `failed`, or `unknown`; management endpoints may return resource states such as `created`, `revoked`, or `active`.
`data.output.resultUrls`	array	Generated result URLs returned by the upstream provider payload.
`data.video_url`	string	Hosted video result URL.
`data.error_message`	string	Failure reason returned when the music task does not complete successfully.
`data.credits_used`	integer	Credits consumed by this request.
`data.credits_refunded`	integer	Credits refunded after failure or partial refund handling.
`data.created_at`	string	Creation timestamp for the returned resource or task record.
`data.updated_at`	string	Last update timestamp for the returned resource or task record.
`data.completed_at`	string	Completion timestamp for the task when available.
`request_id`	string	Request identifier for debugging and support.

Usage Flow

Create a generation task by calling `POST https://gateway.apimall.ai/api/v1/videos/generate`.
Persist `data.task_id` from the create response so you can resume polling later.
Poll `GET https://gateway.apimall.ai/api/v1/videos/{task_id}` until `data.status` reaches `completed` or `failed`.
Read the generated video URLs from the final task payload.

Integration Notes

Store your API key on the server side only.
Persist the returned `data.task_id` immediately so you can resume polling after restarts.
Use an `Idempotency-Key` header when retrying create requests from your backend.
Poll the task endpoint every few seconds with backoff until `data.status` reaches `completed` or `failed`.
Use `data.video_url` as the final hosted asset URL.
