List Realtime Options
Retrieve the complete catalog of supported realtime voice providers and their respective capabilities. Our engine aggregates multiple state-of-the-art Voice AI providers into a single interface. This endpoint acts as a “discovery” route, returning all the configuration data you need to build dynamic agent-creation forms in your own UI.
Authentication Required: You must include your API key in the x-api-key header to authenticate this request.

Understanding the Configuration Payload

A successful request returns a providers array. Currently, the API supports leading realtime engines including OpenAI, Gemini, Ultravox, and xAI Grok. Each provider object contains the following nested data:
  • models: The specific realtime models available (e.g., gpt-realtime, gemini-2.5-flash-native-audio).
  • languages: Found inside each model object, this is an extensive array of supported ISO language codes (like en, es, hi, ja) indicating what languages the model can natively understand and speak.
  • voices: The available voice identities you can apply to the agent.
