What are the bots called that make purchases at speed as soon as the offer opens?

Question

Automation

There are different stores with a limited offer of some product. Let's say sneakers. They sell a new product line, say, once every N months. As soon as they open, bots swoop in and scoop up these sneakers in 3 minutes.
Or not necessarily shops, there are other types of services. For example, "only the first N people this week can apply for service M". You can submit an application only, for example, on Wednesday at 11:00 am
The essence is the same - to buy a product or book a service very quickly.

2) Is there any info on creating such bots?
