### What happened?

What I'm tryin to achieve? Following the guide here to setup the ephemeral token minting for setting up the webrtc connection to azure openai. https://docs.litellm.ai/blog/realtime_webrtc_http_endpoints

My litellm version: v1.82.3-stable.patch.2 Doing a POST to: https://MY_LITELLM_DEPLOYMENT/v1/realtime/client_secrets

With payload and appropriate litellm key: `{ "model": "azure/gpt-realtime"}`

Gives error: ``` { "error": { "message": "/openai/realtime/client_secrets?api-version=2024-07-01-preview", "type": "None", "param": "None", "code": "500" } } ``` Trying with payload : {"model": "gpt/realtime"} gives a 404 resource not found. The litellm config for that model: { "api_base": "https://MY_AZURE_OPENAI_BASE.openai.azure.com", "api_version": "2025-08-28", // this model version is deployed at the azure foundry instance "model" : "azure/gpt-realtime", "api_key" : "THE_AZURE_OPENAI_KEY" }

What works? Directly hitting the azure foundry deployment: https://MY_AZURE_OPENAI_BASE.openai.azure.com/openai/v…
