edge-tts/<model-id>How Edge TTS billing works with kRouter
Edge 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. 11 models are routable as edge-tts/<model>.
Through kRouter, Edge 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 Edge TTS is a one-line model change in your client rather than a rewrite.

Edge TTS FAQ
Is Edge TTS free through kRouter?
Edge TTS is pay-per-token: you bring your own API key and are billed by Edge TTS at their rates. kRouter adds nothing on top and is free and MIT-licensed.
How do I use Edge TTS with Claude Code or Cursor?
Connect Edge 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 edge-tts/<model>.
Which Edge TTS models can kRouter route to?
11 models, including Aria (en-US), Guy (en-US), Sonia (en-GB). Every one is addressed as edge-tts/<model> from any client.
What happens when Edge 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.
