Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # Wan 3.0 Text to Video Create video scenes with Wan 3.0, with optional audio and output up to thirty seconds for longer visual sequences. ## Available Models * **alibaba/wan-3.0/text-to-video** - Generate video scenes from text prompts. ## Duration Options * **2-30 seconds** - Set `duration` as an integer. Default: **5 seconds**. ## Key Features * Generate video scenes from text prompts. * Choose from `480p`, `720p`, `1080p` output resolutions. * Control audio generation with `audio`; it defaults to `true`. ## Advanced Parameters Set `model` and optional `callback_url` at the request root. Place the parameters below inside `input`. Send only the input fields supported by this workflow. Unsupported `input` fields are rejected before credits are deducted. Input URLs must use HTTP(S), include a hostname, and contain no embedded credentials. ### Prompt * `prompt`: Required. Describe the scene and desired motion. * The prompt must not be blank when supplied. Maximum length: **20,000 characters**. ### Resolution * `resolution`: `480p`, `720p`, `1080p`. Default: `720p`. ### Aspect Ratio * `aspect_ratio`: `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16`. Default: `adaptive`. ### Audio * `audio`: Set to `true` to enable generated audio, or `false` to disable it. Default: `true`. ### Seed * `seed` is optional. Supply an integer from `0` to `2147483647`. ### Safety Checker * `enable_safety_checker` is optional. Set it to `true` or `false` to control safety checking. Default: `true`. ## Pricing Pricing depends on the selected model and applicable output settings. Check the Vidgo dashboard for the current rate.
