What the key is billed on
One tracking call per open session: the tracking page load (WebView) orcamera_start (SDK). Switching exercise inside that session (set_exercise on the iframe, startExercise again in the SDK) is not billed again. Closing the iframe or camera, changing the iframe URL, or stop() / start() starts a new call. Details: What counts as one tracking call.
