Confirms or denies that two carriers YOU ALREADY SUSPECT are linked in fact share an identity cluster — the lower-risk alternative to check_carrier_identity's removed linked_carriers field (see schemas.IdentityAssessment's docstring for why that was removed 2026-09-18). This never discloses a carrier's identity to a caller who didn't already have it: both usdot_number_a and usdot_number_b are supplied by you. It only ever answers "do these two specific carriers share a cluster?", never "who is linked to this carrier?" — call check_carrier_identity for that, which stops at a score and a count for exactly this reason. cluster_id is returned only when linked is true, and isn't new information even then — you could obtain the same value directly from either carrier's own check_carrier_identity or screen_carrier_identity response. usdot_number_a and usdot_number_b must differ (invalid_arguments, free — there is no comparison to make). Either number failing to resolve in carrier_identity_cluster is a free not_found, same as check_carrier_identity. Paid — pricier than check_carrier_identity, since it resolves two carriers' clusters per call, not one. A "not linked" result is a complete, valuable answer and bills the same as "linked", same reasoning as check_carrier_identity's cluster_size == 1.
