Free limits
Numeric limits are not recorded in structured form for this provider.
In the provider's words
20 concurrent calls per workspace (Pay-As-You-Go default)
The catch
$10 trial credit with full platform access, granted once per email address. A payment method is required only to buy phone numbers or use the service beyond the free trial. A voice-agent builder (orchestration), not a raw model API. Voice agents cost ~$0.07-$0.31/min after the credit.
Free models: not listed yet.
Get started
This is a first-party API, not OpenAI-compatible, so there is no drop-in base URL. The endpoint, the key and a working example are in the official docs.
