Api Endpoint

Text-to-speech (lite)

Convert text to speech with Kokoro-82M, a fraction of the price of /api/tts. Returns base64-encoded mp3 or pcm. The same request shape and the same ten voice names as /api/tts, mapped to Kokoro's own voices; the voice is synthetic-sounding where the /api/tts and /api/tts-hd tiers are not, which is the whole trade. Use this for high-volume narration, notifications and agent speech where the cost per call matters more than the timbre; use /api/tts or /api/tts-hd when it does not.
