coqui/<model-id>How Coqui TTS billing works with kRouter
Coqui TTS is pay-per-token. You bring your own API key and kRouter routes to it, so you keep your own rate limits and billing relationship. kRouter authenticates it via free. 1 model are routable as coqui/<model>.
Through kRouter, Coqui TTS serves text-to-speech, exposed on /v1/audio/speech. Requests reach it through the same local OpenAI-compatible endpoint as every other provider, so switching to or from Coqui TTS is a one-line model change in your client rather than a rewrite.

Which Coqui TTS models can kRouter route to?
1 model, including Tacotron2 DDC (LJSpeech). Every one is addressed as coqui/<model> from any client.
What happens when Coqui TTS is rate limited?
kRouter detects the limit, parks that account until its real reset time, and fails over to your next connected account or provider — so the request still completes instead of erroring.
