Takes free-form text (e.g., 'Series A startups in USA with 50–200 employees') and returns a list of matching companies. The endpoint interprets natural language queries and applies structured filters such as industries, funding stages, headcount ranges, and locations to identify relevant companies. 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.
