Use this when you already suspect two specific carriers (by USDOT number) are the same operation under different paper and want it confirmed, without receiving any information about a carrier you didn't name. Returns only linked true/false and, when true, the shared cluster_id — never a member list. Billed whenever both USDOT numbers resolve, whether or not they turn out to be linked; supplying the same number twice is free.
