A bot that performs actions on the site?

Question

Bots

Site https://www.farpost.ru/
On the site, the ad with the highest price is at the beginning.
I found out that there are bots that can automatically raise the price when the price is higher.
How do they do it if farpost doesn't have api ?
Are they just pinging the site with queries and following a certain ad?

Answer 1

If there is no public api, this does not mean that it does not exist at all) It would be strange for such a large site not to have api, even for a limited circle of people.
If there is no api for ordinary users, then there is only one way out - parsing.

Answer 2

I will support Artem , for example:
https://www.farpost.ru/tambov/auto/sell_spare_part...
and you get json with data, where there is a price, id, etc.
So just knock there from time to time and check the prices.
