Example status: Legacy

This example uses stale configuration, allows unauthenticated resource creation, and does not implement complete teardown. Its checked-in configuration also illustrates plain variables for credentials. Do not use it as a production starting point.

This is a historical example of connecting OpenAI's WebRTC Realtime API with Cloudflare Realtime SFU. The CALLS_* environment variable names are retained for compatibility with the implementation.

Please update the environment variables in wrangler.toml

OPENAI_API_KEY = "<openai api key>"
OPENAI_MODEL_ENDPOINT = "https://api.openai.com/v1/realtime?model=gpt-4o-realtime-preview-2024-10-01"
CALLS_BASE_URL = "https://rtc.live.cloudflare.com/v1/apps"
CALLS_APP_ID = "<calls app id>"
CALLS_APP_TOKEN = "<calls app token>"

Install dependencies if you run this for first time:
