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. A fresh temporary download URL for the owned speech MP3.{
"data": {
"downloadUrl": "https://files.example.com/launch-script-speech.mp3"
}
}
Result fields
| Field | Description |
|---|---|
data.downloadUrl | Temporary MP3 download URL for this history item. |
Operation notes
- This read never generates speech or consumes media-generation credits. Integration call limits still apply.
- The filename is derived from sourceFileName when present, otherwise voicecheap-tts-speech.mp3. URLs are temporary.
- Speech history and custom voices belong to the authenticated account. Team billing does not grant access to another member’s speech or voices.

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