Kagi's search results (at least used to) include many Google search results mixed in with results from other sources. That used to be explained on Kagi's main webpage, but I don't see it there now. (And I don't know who pays whom for what in that type of arrangement.)

Kagi uses a third party API that scrapes Google results for their searches. Possibly SerpAPI? Either way, Google doesn't get paid because you can't pay for the kind of search access they want.
