Fitment API for Shops and Sellers
A developer-friendly API for fitment and reverse compatibility targets a clearer B2B willingness-to-pay signal than consumer subscriptions alone. Shops, marketplaces, and niche tools can justify recurring spend if the API saves support time, powers search, and improves buyer confidence.
これが重要な理由
If you run a small automotive business online, fitment questions create friction at every step. Customers hesitate to buy, support inboxes fill with repetitive compatibility checks, and your current tools often only handle basic vehicle-to-part lookup. You need a service that can answer both direct and reverse fitment questions programmatically, handle messy model names, and expose enough trust metadata that your team is comfortable putting the output in front of buyers. Without that, you either send people away to do their own research or absorb the operational cost of answering the same question over and over.
