Look up multiple carriers by DOT number in a single request (max 50). Returns the core carrier profile for each match. Have MC numbers instead of DOT numbers? Use Bulk Lookup by MC.
This endpoint requires an API key. See Authentication.
Bulk lookup returns the core carrier profile only — safety, insurance, risk score, and related companies are not included. For those, fetch each carrier individually via GET /v1/carriers/{dot_number}.
