Technical details
Endpoint
GEThttps://openrouter.mpp.tempo.xyz/v1/audio/models?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what speech or transcription models are available on OpenRouter before making an audio generation or transcription call — especially when you need to compare pricing across models or find which voices are supported. Prefer this over general OpenRouter model listings when you specifically care about audio/speech capabilities rather than chat or video models.
Side effects
- Service temporarily unavailable (5xx) if OpenRouter backend is down
- Empty or incomplete model list if no audio models are currently configured
- Stale pricing data if catalog has not been recently refreshed
