# Wan2.7 Text-to-Video

> Video Generation

Submit an asynchronous task. The model and parameters in the request body should be filled according to this model documentation. The response will return a task ID.
Wan2.7-T2V supports generating smooth, high-quality videos from text.
Supports audio-driven generation: You can provide an audio file to synchronize character movements with the audio rhythm.
Text-to-video tasks take 1-5 minutes. The API uses asynchronous calls.

## Endpoint

`POST https://api.modelverse.cn/v1/tasks/submit`

## Request Body

## Responses

- **200** — Task submitted successfully.
- **400** — Invalid request parameters.
- **default** — Error response.
