14 years ago, when low cost flights became popular in Europe with Ryanair, I moved to London with a friend for a year. To get the cheapest price, we had run a simple perl crawler in a cronjob to monitor the prices and it sent us a text over some free api. We didn't realize that time that this could have been a massive service and over the years many businesses basically executed on the same basic idea.
