The landing page’s live latency demo. Reach it as client.demo on a QumoClient.

createSession

Starts a demo session: a broadcast path of its own and a short-lived credential to publish and subscribe to it. It needs no account, and sends nothing of the caller’s. It throws an APIError with status 404 when the deployment has no demo configured, 429 when there have been too many sessions (from this address or in all), and 5xx when one could not be started. Types: DemoSession
