How it works

Your server calls POST /v1/live-video/sessions with this model id. We check your key and credits, hold the cost of the session, and return a short-lived credential for the host.
Your browser or app streams from the host directly with that credential — the video never passes through our servers and the host API key never reaches the browser.
Your server sends a heartbeat while it runs and ends the session when the user leaves. You pay per second the session was live, up to 600 s per session.
