Questions
Straight answers.
TTS keys, pricing, and the basics.
01Is this a TTS reverse proxy?
In effect, yes. Your request hits our gateway, we route it upstream to a provider serving TTS, and the response comes back the way your client expects.
02Do I need my own provider account?
No. We run the upstream accounts. One SilvR key covers TTS and the rest of the catalog.
03Can I use TTS for free?
Yes. Every account starts on the free plan with a daily allowance you can spend on any model in the catalog, TTS included.
