Among the various rulings, Google is supposed to provide access at market rates... which they are. At least for what is published: $5 per thousand queries is market rate for a product like this - see Brave's Search API pricing https://api-dashboard.search.brave.com/app/plans?tab=ai.

Granted, that is scoped to 50 domains. But we don't know if the enterprise package, which allows full web search, isn't roughly market rate.
