title: Interaction between parser and telegram bot
body: <p>I wrote a parser that collects air quality data from the resource <a href="https://www.iqair.com" rel="nofollow noreferrer">https://www.iqair.com</a>
  and I want to configure its interaction with the telegram bot.
  I do not want a request to the site to be sent for each request of the telegram bot user. How can you send a request every 30 minutes, save it somewhere, and, at the request of the user, pass it on to him? So that it all works on the server, at the same time</p>
