# Get a voice preview

> Get a playable temporary URL for your unsaved cloned or designed voice preview. Use voices_save_preview to keep it before it expires.

Get a playable temporary URL for your unsaved cloned or designed voice preview. Use voices\_save\_preview to keep it before it expires.

```http theme={null}
POST https://api.voicecheap.ai/v1/actions/voices_preview_get
```

## Authentication and permissions

<ParamField header="x-api-key" type="string" required>
  Send a VoiceCheap API key in this header. Authorization: Bearer with the same API key is also supported. OAuth access tokens are accepted only by
  MCP, not by this REST endpoint.
</ParamField>

Required permissions: `voices:read`.

An active paid subscription is required. Permissions do not change team roles, resource ownership, media credits, or plan limits.

## Parameters

<ParamField body="previewId" type="string" required>
  Text value.

  Format: "uuid". Pattern: `^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12})$`.
</ParamField>

<Accordion title="Complete input schema">
  The JSON Schema below preserves the exact field names, nested types, defaults, bounds, and accepted values exposed by discovery. Additional cross-field rules are listed in the operation notes.

  ```json theme={null}
  {
    "type": "object",
    "properties": {
      "previewId": {
        "type": "string",
        "format": "uuid",
        "pattern": "^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12})$"
      }
    },
    "required": ["previewId"],
    "additionalProperties": false
  }
  ```
</Accordion>

## Request examples

Replace example resource identifiers and media keys with values returned for your account. Keep the request identifier stable when retrying the same mutation.

<RequestExample>
  ```bash cURL theme={null}
  curl --request POST 'https://api.voicecheap.ai/v1/actions/voices_preview_get' \
    --header "x-api-key: $VOICECHEAP_API_KEY" \
    --header 'Content-Type: application/json' \
    --data '{"previewId":"44444444-4444-4444-8444-444444444444"}'
  ```

  ```javascript JavaScript theme={null}
  const input = {
    previewId: '44444444-4444-4444-8444-444444444444',
  };
  const response = await fetch('https://api.voicecheap.ai/v1/actions/voices_preview_get', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.VOICECHEAP_API_KEY,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify(input),
  });
  const body = await response.json();
  if (!response.ok) throw new Error(body.code + ': ' + body.message);
  console.log(body);
  ```

  ```python Python theme={null}
  import os
  import requests

  response = requests.post(
      "https://api.voicecheap.ai/v1/actions/voices_preview_get",
      headers={"x-api-key": os.environ["VOICECHEAP_API_KEY"]},
      json={"previewId": "44444444-4444-4444-8444-444444444444"},
      timeout=120,
  )
  body = response.json()
  if not response.ok:
      raise RuntimeError(f"{body.get('code')}: {body.get('message')}")
  print(body)
  ```
</RequestExample>

## Response

A successful first execution returns HTTP 200 with the operation result under data. A replay may return saved request state instead. The example shows one supported response, not every optional field.

One active owned voice preview, with a refreshed temporary playback URL and its expiry.

<ResponseExample>
  ```json HTTP 200 theme={null}
  {
    "data": {
      "id": "44444444-4444-4444-8444-444444444444",
      "kind": "clone",
      "name": "Studio narrator",
      "previewUrl": "https://files.example.com/narrator-preview.mp3",
      "expiresAt": 1792238400000,
      "durationSeconds": 10
    }
  }
  ```
</ResponseExample>

## Result fields

| Field | Description |
| - | - |
| `data.id` | Candidate UUID for voices\_save\_preview. |
| `data.kind` | clone or design. |
| `data.name` | Candidate display name. |
| `data.previewUrl` | Fresh temporary playable audio URL. |
| `data.expiresAt` | Candidate expiry as a Unix timestamp in milliseconds. |
| `data.durationSeconds` | Preview audio duration in seconds. |

## Operation notes

* previewId is the candidate UUID returned in voicePreviews by voices\_preview\_clone, voices\_design, or voices\_list.
* Only ready, unsaved, unexpired previews are visible. A saved candidate moves to voices\_list as clone:\<previewId>. Expired, saved, missing, and unowned candidates return VOICE\_PREVIEW\_NOT\_FOUND here.
* The URL is temporary and can expire before expiresAt. Save the chosen candidate with voices\_save\_preview before the preview itself expires.
* Speech history and custom voices belong to the authenticated account. Team billing does not grant access to another member’s speech or voices.

## Usage

Each successful invocation consumes one monthly API/MCP call. Media credits and the operation's own generation allowances also apply.
