polly/<model-id>How AWS Polly billing works with kRouter
AWS Polly 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 apikey. 4 models are routable as polly/<model>.
Through kRouter, AWS Polly 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 AWS Polly is a one-line model change in your client rather than a rewrite.
Use AWS Secret Access Key as API key; set providerSpecificData.accessKeyId and optional region.

AWS Polly FAQ
Is AWS Polly free through kRouter?
AWS Polly is pay-per-token: you bring your own API key and are billed by AWS Polly at their rates. kRouter adds nothing on top and is free and MIT-licensed.
How do I use AWS Polly with Claude Code or Cursor?
Connect AWS Polly 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 polly/<model>.
Which AWS Polly models can kRouter route to?
4 models, including Standard, Neural, Long-form. Every one is addressed as polly/<model> from any client.
What happens when AWS Polly 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.
