Paginated search with text, filters, and optional geo/radius support.

When using geo search (lat/lon), each result includes a distance_miles field with the distance from the search point.

Geo resolution is state-level. Every carrier in a state shares the same geocoded point — the centroid of that state. As a result:

A radius smaller than the diameter of a state will return very few or zero results.
Practical floor: ~200 miles to reliably hit carriers in neighboring states’ centroids.
Use state=XX for tighter location filtering at the state level, or city=... for city-level filtering by name (string match on the carrier’s physical address city).

This is a limitation of the daily ETL’s geocoding step, not a query bug. Real per-carrier geocoding is on the roadmap.

Query Parameters

string

Text search (matches legal name and DBA name)

string

Filter by MC number. To resolve many MC numbers at once, use Bulk Lookup by MC instead of looping this endpoint.

string

Filter by city

string

Filter by state (2-letter code)

string

default:"ACTIVE"

Filter by carrier status. Use ALL to include inactive carriers

string

Filter by cargo type

string

Filter by entity type (e.g. CARRIER, BROKER, FREIGHT FORWARDER, SHIPPER)

string

Filter by company officer name (matches either of the two officer slots)

string

Filter by phone number

string

Filter by email address

integer

Minimum power units

integer

Maximum power units

number

Latitude for geo search (requires lon)

number

Longitude for geo search (requires lat)

integer

default:"50"

Search radius in miles (max: 200)

integer

Minimum months of active authority (filters by common authority date)

string

Sort field and direction. Options: name, name_asc, name_desc, dot, dot_asc, dot_desc, fleet_size, fleet_size_asc, fleet_size_desc, distance, distance_asc, distance_desc (distance options require geo search)

integer

default:"1"

Page number

integer

default:"25"

Results per page (max: 100)
