With Google's search engine making almost $200 billion a year in revenue, I'm not sure Kagi could afford what market rates would be here. They also spent billions developing the technology to crawl, index, and rank billions of pages, factoring that in, again I don't think a good price can be put on it.
What even is market rate? Kagi themselves admits there's no market, the one competitor quit providing the service.
Obviously Google doesn't want to become an index provider.
According to the article, the judge's memorandum said about index data access:
> Google must provide Web Search Index data (URLs, crawl metadata, spam scores) at marginal cost.
I'm guessing that the "marginal cost" of a search is small and it's not connected to the how much ad revenue that search is worth.
