How Google TTS billing works with kRouter

Google 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. 60 models are routable as google-tts/<model>.

Through kRouter, Google 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 Google TTS is a one-line model change in your client rather than a rewrite.

Google TTS FAQ

Is Google TTS free through kRouter?

Google TTS is pay-per-token: you bring your own API key and are billed by Google TTS at their rates. kRouter adds nothing on top and is free and MIT-licensed.

How do I use Google TTS with Claude Code or Cursor?

Connect Google TTS in the kRouter dashboard, then point your tool at kRouter's local endpoint (http://localhost:20128/v1) with a kRouter API key. Any OpenAI-compatible client works, and models are addressed as google-tts/<model>.

Which Google TTS models can kRouter route to?

60 models, including Afrikaans, Arabic, Bulgarian. Every one is addressed as google-tts/<model> from any client.

What happens when Google 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.
