API Documentation

Introduction

The FreightAPIs API provides programmatic access to the National Motor Freight Classification database, Amazon drop point locations, and carrier location data for 9 major carriers — ABF Freight, Central Transport, CEVA Logistics, C.H. Robinson, Estes Express, GLS US, Saia LTL, SEKO Logistics, and TForce Freight. All endpoints share a single, consistent REST interface.

Authentication

Authenticate by passing your API key in the Authorization header as a Bearer token.

You can generate and manage API keys from your dashboard after signing up. Each key is displayed only once at creation time — store it securely.
