Api Endpoint

check_carrier_identity

Use this when a carrier looks suspicious — a name change, a new USDOT number tied to an old fleet, a business you suspect re-registered after a revocation — and you need the full evidence: every other USDOT number sharing a contact identifier with it, and whether any of them carries a revocation or suspension motive. Call the free screen_carrier_identity first if you only need the flag and a count. Billed whenever the USDOT number resolves, even with no links found.
