There is API documentation. Study. Send a message on an event.

Answer 2

No way. Using the API, there is no way to get the event of replenishment of votes and even a simple number of votes.
Although it is possible to parse the site from time to time and when the number of votes has changed, send a message on behalf of the bot.
