## Response

The request returns the task with `status: "initializing"`. Poll [GET /api/asset\_generator/\{id}/](/api-reference/ai-generation/get-ai-generation-) until `status` is `done` or `failed`, or pass a `webhook_url` to be notified. A finished task lists its files in `assets` and the credits it charged in `credits_used`.
