Google Scholar search - returns academic papers with titles, authors, publication venues, years, citation counts, links, and snippets. Use as_ylo/as_yhi to filter by publication year range. Use for academic research, literature reviews, or citation analysis. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.
