How to track a live broadcast on VK and youtube?

Question

API

Tell me how you can track the beginning of the broadcast in VK and YouTube for a specific user. There are no problems with twitch, there the status is checked through the api, but I can’t find it right away on these two platforms. Required for use in bash scripts.
