LDInspector

[Stefan Frenz]

They probably have BrickLink API access. Since BrickLink requires you to have a static IP and there's no way we're going to pay for that, BrickLink API access (However useful it may be) isn't going to happen anytime soon here at LDraw.

The other option is to severely throttle your page requests. 2 sec between requests or something ridiculous like that.

Indeed I don't have static IP at home (not even real IPv4 anymore).    For some "long term" huge pausing between requests would do it, yes, but for my use-case I would interactively search for a part replacement based on price (not only on price, but as one of many criteria), so for each part to be replaced I would search for at least a dozen other ones. If there is no online-database with hard access restriction, I was in hope to get something like Rebrickable's downloadable set inventories files with price per colored part...
