## Endpoint

```http theme={null}
POST https://routerbase.com/v1/videos/generations
```

This is an **async** endpoint. The POST returns immediately with
`{id, status: "pending"}`; poll `GET /v1/videos/generations/{id}`
until `status` is `success` (with `data: [{url}]`) or `failed`.

## Supported Tasks

* [`text-to-video`](/minimax-h3-api/text-to-video) — `minimax/minimax-h3-t2v`
* [`image-to-video`](/minimax-h3-api/image-to-video) — `minimax/minimax-h3-i2v`
* [`reference-to-video`](/minimax-h3-api/reference-to-video) — `minimax/minimax-h3-r2v`
