## Inputs

Pass reference media in the `references` array (0–12 items). Optional. Each item accepts exactly one of:

* `url` — a direct, publicly accessible file URL
* `asset_id` — the ID of an existing asset in your Hoox space (e.g. a previous generation)
* `avatar_id` — the ID of an avatar defined in your Hoox space

## Custom settings

These keys go inside the `model_settings` object of the request body.

| Key                  | Type    | Default | Affects cost | Description                                                                                                                                                                                                                                                                                                              |
| -------------------- | ------- | ------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `forceReferenceMode` | boolean | `false` | yes          | Use the attached media as subject/style references instead of the video's first frame. Reference mode turns on by itself from 3 references, or as soon as a video or an audio is attached; set this to get it with fewer — one reference is enough. Reference mode is billed at its own rate, so this changes the price. |

## Pricing

Default parameters (5s at `768p`): **\~4 credits / generation**.

For exact pricing with your own parameters, call [`/asset/pricing`](/api-reference/assets/pricing) with the `model` and any parameters that affect cost.
