Retrieve ocean freight rate quotes and compare schedules across carriers using a neutral rate management platform API

Steps

1. Identify a neutral ocean freight rate API provider (such as Freightos, Flexport, or a similar freight intelligence platform) and obtain API credentials through the platform's developer program.
2. Submit a rate query specifying origin port (UN/LOCODE), destination port, cargo weight, container type (20GP, 40GP, 40HC, 45HC), commodity (for surcharge eligibility), and requested shipment date.
3. Parse the rate response array; for each quote extract the base ocean freight rate, applicable surcharges (BAF, CAF, PSS, GRI), transit time, carrier name, and validity expiry date.
4. Sort quotes by total all-in cost including surcharges, then by transit time, and present the top options to the booking decision workflow; do not compare base rates alone as surcharges can represent 40-80% of total cost.
5. Before booking, re-validate the rate with the carrier directly or through the platform's booking API; spot rates may expire between quote and booking, especially in volatile markets.
6. Store rate quotes with their validity window and all-in breakdown for freight audit purposes; compare invoiced amounts against quoted rates to detect overbilling at the auditing stage.
