Free limits
Numeric limits are not recorded in structured form for this provider.
In the provider's words
Pay As You Go: 15 concurrent TTS streams, 100 TTS requests/min, 450M chars/month cap; 100 concurrent STT streams; 20 concurrent agent calls (bounded by the $10 credit)
The catch
$10 starting credit on Pay As You Go. The models pricing page lists 15 concurrent TTS streams while the API reference still says 1 active TTS request per account — inconsistent. The models table shows Voice Cloning 'No' for Pay As You Go although the TTS card advertises instant cloning. Card and commercial terms not stated. /pricing now redirects to /pricing/agents.
Free models: not listed yet.
Get started
