Frequently asked questions
- How do I generate speech through the API?
- POST to /v1/audio/speech with a model slug and your input text. You get back audio, billed per use from your credit balance.
- What can I build with the audio API?
- Voiceovers and narration, accessibility (text-to-speech for apps and documents), and spoken interfaces for voice agents and bots.
- Is there a subscription?
- No. Audio uses the same pay-per-use credit balance as every other model. You pay only for what you generate.
