# Assets overview

> API-scoped materials and voices

Open API **assets** are resources you create and reference by ID in task requests. There are two types:

| Asset        | ID field     | Purpose                                                                                                                                     |
| ------------ | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------- |
| **Material** | `materialId` | Video or audio used as input (mainly media translation). Usable only after the full [upload](/guides/assets/material-upload) flow completes |
| **Voice**    | `voiceId`    | System preset or cloned voice used in TTS                                                                                                   |

## API-only storage

Materials and voices created through the API are not shared with files or voices you manage on [vmeg.ai](https://www.vmeg.ai/home). Use `/openapi/v1/assets/**` only. API tasks are separate too; see [Products overview](/guides/products/overview).

List and delete operations return only assets tied to your **API Key**. Voice list endpoints use the same scope.

## Typical flow

```text theme={null}
Complete full material upload → registered materialId → media translation task
Voice clone task → voiceId → TTS task
List basic voices → voiceId → TTS task
```
