I don't think so. I was surprised to learn on their Discord that they rely heavily on paid results from Google's API and other search APIs. Not sure what they do with it but it's pretty amazing how they improve the results.

Right, that's scraping results, not from an API that doesn't exist. What exists is Custom Search from Google and that's an API to search results on your own website.
I was looking into that, looks like they have an API but it's limited to 10k requests per day, and TOS says you can't blend the results with other sources.
