# Preview Clone

`GET /api/voice-clones/{clone_id}/preview`

## Request

- Base URL: `https://api.dialogbrain.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.dialogbrain.com/api/voice-clones/{clone_id}/preview`
- Auth: none declared

Cached preview WAV. First call routes through tts_registry preview
with the cloned vendor_voice_id, stores the result at
voice-clones-previews/{vendor_voice_id}.wav, and serves a presigned
URL. Subsequent calls skip the vendor and serve from the cache.

Cache key uses `vendor_voice_id` (NOT the BIGSERIAL id) so a sequence
reuse edge case can't serve a stale blob for a different clone.

Cross-workspace requests return 404.

## Path parameters

- `clone_id` integer, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
