Scraping is LEGAL, all search engines scrape to some degree for example, there is a fair use component, so you can't "scrape" 100% of a site and stick it on your domain, but you can still scrape more than zero. In general it is leaning more acceptable than less.
Yeah I understand that part, my question is about showing the scraped data to your users.
https://www.yummly.com/ used to have a paid API for recipe search and currently still lets users search their index. Did they have to go and get permission from each site that they index or is it fair use?
It looks a shade more detailed than google's recipe cards, they link back to the original source for the instructions, I would bet they didn't get permission, and that they count as a fair-use search engine. The law isn't (can't be) perfectly prescriptive here, there's some line that you have to sue about to know if it has been crossed.
