Use this to check one applicant carrier against a roster of carriers you already
Use this to check one applicant carrier against a roster of carriers you already work with — e.g. catching one you previously cut for a revocation or suspension trying to re-enter under a new USDOT number. Returns whether it's linked to any roster member and which ones, never a carrier outside your own roster. Metered: a base price plus a per-roster-entry price, both shown in get_catalog; billed whenever the applicant resolves, whether or not it matches anything on your roster.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
