website scraping each second without getting too many requests and account being banned

Job ID: 33515992

Budget: $10 – $30 USD

I have a website that I should check its calendar for an appointment each second to know the last update and available date to select as an appointment date and time. I cannot refresh the website every second due to getting the Too Many Requests errors. Also refreshing too much lead to account blocking.
My code is already written by Python and Selenium to select the time and date automatically. But alerting about the last update and first available appointment is my problem. I need someone to solve this issue, read the data each second and save it in a variable as an input to my bot.
