}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 aproviders 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 (likeen,es,hi,ja) indicating what languages the model can natively understand and speak.voices: The available voice identities you can apply to the agent.
