Commercial use is NOT allowed on the free plan (the $5/mo Pro plan adds a commercial licence). Low-latency streaming voice over WebSocket/REST; own API (not OpenAI-shaped).
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.
