RockAuto API

Walk the RockAuto parts catalog by vehicle and get part prices, brands and fitment notes as JSON.

RockAuto is a US online auto parts store with a catalog organized by vehicle. The API.SH RockAuto API walks that catalog one level at a time: makes, years, models, engines, part categories and part types. For one vehicle and part type it returns every listed part with brand, part number, quality group (Economy, Daily Driver, Premium and others), price, core charge, total, fitment notes, markets, purchase options, images and the part's info link.

API.SH vs the official RockAuto API

RockAuto does not offer a public API; search results show only its catalog, newsletters and an unofficial app. API.SH reads the public RockAuto catalog and returns it as JSON.

Skip maintaining a RockAuto price scraper from GitHub: API.SH walks the catalog for you with one key and a fixed price per call.
