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 2.7 Video Text to Video Create 5, 10, or 15-second videos with Wan 2.7 using written scenes and optional audio input at up to 1080p. ## Available Models * **alibaba/wan-2.7/text-to-video** - Generate video scenes from text prompts. ## Duration Options * **5, 10, 15 seconds** - Set `duration` as an integer. Optional. Default: **5 seconds**. ## Key Features * Generate video scenes from text prompts. * Choose from `720p`, `1080p` output resolutions. ## Advanced Parameters Set `model` and optional `callback_url` at the request root. Place all workflow parameters, including output options, 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. `duration` and `seed` also accept integer strings such as `"5"`; decimal numbers such as `5.0` and decimal strings such as `"5.0"` are rejected. Null or empty values use the default duration or omit the seed. Supported boolean fields also accept `0`/`1` and case-insensitive strings `true`/`false`, `1`/`0`, `yes`/`no`, `y`/`n`, and `on`/`off`; null omits the field. Surrounding whitespace is trimmed, and resolution values are case-insensitive. ### Prompt * `prompt`: Required. Describe the scene and desired motion. Maximum: **5,000 Unicode characters**. * Leading and trailing whitespace is trimmed. A nonblank prompt is required. ### Audio URL * `audio_url`: Optional. Provide the input audio URL. Use a publicly accessible HTTP(S) URL. ### Aspect Ratio * `aspect_ratio`: Optional. Accepted values: `16:9`, `9:16`, `1:1`, `4:3`, `3:4`. Default: `16:9`. ### Resolution * `resolution`: Optional. Accepted values: `720p`, `1080p`. Default: `720p`. ### Seed * `seed`: Optional. Set the generation seed. Integer from `0` to `2147483647`. ### Safety Checker * `enable_safety_checker`: Optional. Control safety checking. Use `true` or `false`. ## Pricing Usage equals output seconds multiplied by the selected resolution rate. See [Pricing](https://vidgo.ai/apis/api-pricing) for current rates. Credits are deducted on submission and refunded if the task fails. ## OpenAPI ````yaml api-manual/video-series/alibaba-wan-2-7-text-to-video.json POST /api/generate/submit openapi: 3.0.0 info: title: Vidgo API - Wan 2.7 Video Text to Video description: Wan 2.7 Video Text to Video through the Vidgo unified submit API. version: 1.0.0 servers: - url: https://api.vidgo.ai security: - BearerAuth: [] paths: /api/generate/submit: post: tags: - Video Series summary: Wan 2.7 Video Text to Video description: >- Send only the fields shown for this workflow.
