Environment / auth

THREE_WS_BASE
Base URL of the three.ws API that serves the audio/animation endpoints. Override only when self-hosting or targeting a preview deployment.
THREE_WS_API_KEY
secret
Optional three.ws API key (bearer token). Raises the metered TTS/ASR/Audio2Face rate limits and unlocks your own private/unlisted motion-capture clips. Leave unset to use the public surface anonymously.
THREE_WS_TIMEOUT_MS
Per-request timeout in milliseconds for the live audio/animation calls (synthesis and recognition are real upstream model calls).
