As answered by people managing ZIP Code API and TimeToCargo.
TimeToCargo's answer:
TimeToCargo is primarily designed for logistics companies that manage maritime container shipments across multiple carriers. It is also suitable for freight forwarders, exporters, importers, supply chain teams, and other businesses involved in sea freight.
TimeToCargo's answer:
TimeToCargo brings container tracking data from more than 100 shipping lines into one standardized interface. It helps logistics teams save time by consolidating container status, shipment events and dates, vessel details, ETA, ports, latest available location, event notes, and shipment routes into clear reports.
The service also supports automatic carrier detection, bulk container uploads, API integration, and webhook notifications.
TimeToCargo's answer:
TimeToCargo reduces the time spent checking different carrier websites and manually consolidating shipment information. Users can track containers by container number, bill of lading, or booking number, manage multiple shipments in one place, and transfer tracking updates to their internal systems through the API and webhooks. Flexible monthly and annual plans make the service suitable for both smaller teams and companies managing larger tracking volumes.
TimeToCargo's answer:
TimeToCargo was developed around a common logistics challenge: shipment information is often fragmented across multiple shipping-line websites and presented in different formats. The service aims to simplify this process by consolidating container tracking data into a single, standardized platform, helping logistics teams spend less time collecting information manually.
TimeToCargo's answer:
The TimeToCargo provides a tracking API and webhook functionality for integration with customer systems. Further details about the backend infrastructure and complete technology stack are not publicly disclosed.
