Goo-net Exchange Data Parser & API

Goo-net Exchange is the international export arm of Japan’s leading used-car portal, listing around 257,000 vehicles — and Carapis extracts its full listing data, including detailed chassis-code → trim/spec mapping, auction-sheet grades and export pricing, through one REST API. Operated by PROTO Corporation, Goo-net Exchange carries the richest spec data in the Japan-export cluster, mapping each car’s chassis code to a precise trim and equipment record.

What is Goo-net Exchange?

Goo-net Exchange is the English-language, export-facing version of Japan’s Goo-net used-car portal, run by PROTO Corporation. It lists roughly 257K cars and connects global buyers with Japanese exporters. Its standout feature is detailed chassis-code-based spec mapping: from a vehicle’s chassis code, Goo-net Exchange resolves the exact trim, grade and factory equipment — making its records unusually precise for the Japan-export market.

Market Position

Goo-net Exchange is a major Japan-export portal, listing ~257K cars (Goo-net Exchange). It sits in the Japan-export cluster alongside BE FORWARD, SBT Japan, TCV and Car From Japan, all funneling JDM stock to Africa, the Caribbean, SE Asia, the Middle East and Oceania. As the export arm of PROTO Corporation’s domestic Goo-net portal, it inherits Japan’s most detailed used-car spec database — chassis-code → trim mapping — which makes its data the richest for spec-accurate import decisions. Because export supply traces back to common Japanese auctions, its auction-sheet grades share the cluster’s standard structure.

Data Fields Available

Carapis extracts a complete structured record from each Goo-net Exchange listing:

• Vehicle identity — make, model, grade/trim, chassis code (the standout field: resolves exact trim/spec), model year, engine size, fuel type, transmission
• Condition — mileage, auction-sheet grade (standardized condition score), overall condition notes
• Pricing — listed price plus FOB export price
• Specification — factory options and equipment, derived from chassis-code mapping
• Listing context — exporter/seller, location, photo gallery

The chassis-code-to-trim mapping is what makes Goo-net Exchange uniquely valuable: it removes ambiguity about exactly which grade and equipment a JDM car carries — delivered as structured fields rather than free text.
