Why the search API rules limit conversion rate and prohibit the automatic collection of links to a booking?

Yes, we prohibit sending automatic requests, especially just to get prices. Agencies pay revenue for each request to GDS (Global Distribution System). So, high amount of requests without bookings will cost a lot for them. They will address us to ask why there are no bookings with such big amount of requests being made. We and you get revenue from agencies, so we need to respect the rules.
