Cat Digital Marketplace API
The Cat Digital Marketplace publishes a catalog of Caterpillar APIs spanning asset telematics, fleet management, fuel data, utilization, hours/odometer, and geofencing. Developers subscribe via the Cat Digital portal to receive API credentials and execute calls against the Cat Connect and VisionLink platforms. All catalog APIs are fronted by the Apigee gateway at services.cat.com, which returns a uniform {code, description} JSON error envelope.
