About
plan.parts is a relay API platform that transmits data from automotive parts databases through a single unified interface. We do not own or license the source data β we provide programmatic access to it. You pay per request, only when you get data back. No subscriptions, no servers to rent, no parsers to write.
API

Equipment catalog for ATVs, motorcycles, watercraft and more. Full part trees with diagrams and article numbers.
Official OEM parts catalog for Volkswagen Group vehicles. VIN lookup, genuine part numbers, assembly diagrams, and supersession chains.
