- URL: `https://api.kugelaudio.com/v1/voices/{voice_id}/generate-sample`

Generate a sample WAV for a voice you own.

Requires at least one reference audio to be uploaded first. The
sample is generated through the TTS engine under an admission lease
(rate limit + concurrency + size cap) but is never charged — no
usage row is written, matching v1 — and stored via the admin seam.

## Path parameters

- `voice_id` string, required

## Response `200`

Successful Response

- GeneratedSampleInfo: Stored sample location returned after free sample synthesis.
  - `sample_s3_path` string, required
  - `sample_url` string, nullable

## Changes

  - added the optional property `sample_url` to the response with the `200` status
  - added the required property `sample_s3_path` to the response with the `200` status
