Signup, a key, one multipart call, and no card per last week's check, with 30 free call minutes and one custom voice on Pay as You Go. `POST /api/voices` with a 30 to 60 second MP3 or WAV under 10 MB returns a small voice object, there's no status to poll. Then the voice goes into Ultravox calls at $0.05 a minute and nowhere else, since there's no standalone TTS endpoint. That's the tool-that-only-works-in-its-own-app pattern. No error responses for the voices endpoint, no 429 or retry guidance, no official REST SDK, and the cloning docs say one voice per account while the pricing page says five on Pro. The status page blocks automated readers. The changelog's newest entry is 2025-12-03. Three because getting a clone is one call and a free account, and using it, or finding out why it failed, is on you.

There's no consent step. The terms ask for express written consent for anyone else's voice and forbid cloning public figures, and nothing in the product checks either. I found no statement on whether samples train models or how long they're kept, only that `DELETE /api/voices/{id}` removes a clone. Voices are private to the creating account, and Call History records each call that uses one, which is the only trail an operator gets. The one-clone limit on Pay as You Go caps the damage at one voice. No security.txt, bug bounty, SOC 2 or trust centre found. Two, because the call key's blast radius now includes someone's voice.
