Submit the request with `VIDGO_API_KEY`. Save the returned `task_id` to track generation. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. With a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task reaches `finished` or `failed`. # Wan 2.5 Text to Video Create 5 or 10 second videos from text with synchronized audio and landscape or portrait output up to 1080p. ## Available Model * `alibaba/wan-2.5/text-to-video`: Generate a video scene from a text prompt. ## Request Parameters Set `model` and optional `callback_url` at the request root. Place the following generation parameters inside `input`. ### prompt * `prompt` (string, required): Describe the subject, scene, and motion. Use 1–1500 characters after trimming surrounding whitespace. ### aspect\_ratio * `aspect_ratio` (string, required): Frame dimensions in pixels (`width*height`): `832*480`, `480*832`, `1280*720`, `720*1280`, `1920*1080`, `1080*1920`. ### duration * `duration` (integer, optional): Video duration: 5 or 10 seconds. Default: 5. ### audio * `audio` (string, optional): Optional audio file URL to supply a recording for the video. ### negative\_prompt * `negative_prompt` (string, optional): Optional description of elements to exclude from the scene. ### seed * `seed` (integer, optional): Optional integer random seed for reusing generation settings. ## Retrieve the Video Query the task with `task_id`. Continue polling while `status` is `not_started` or `running`. At `finished`, read the video URL from `data.files[].file_url`. At `failed`, read `data.error_message` for the error details. ## OpenAPI ````yaml api-manual/video-series/alibaba-wan-2-5-text-to-video.json POST /api/generate/submit openapi: 3.0.0 info: title: Vidgo API - Wan 2.5 Text to Video description: >- Create 5 or 10 second video scenes from text with Wan 2.5, with audio input and prompt controls to shape the look of each clip. version: 1.0.0 servers: - url: https://api.vidgo.ai security: - BearerAuth: [] paths: /api/generate/submit: post: tags: - Video Series summary: Submit Wan 2.5 Text to Video Task description: >- Send only the fields shown for this workflow.
