eBay Browse API (vehicles) vs Vehicle Databases for AI agents
eBay Browse API (vehicles) is eBay's Buy API for searching and reading eBay listings by keyword and category; the docs read today cover vehicle parts fitment but do not show a vehicle-specific listings guide. Vehicle Databases is a set of 25+ vehicle data APIs (VIN decode, market value, history, sales and auction history, recalls); its Used Car API looks up past listings by VIN rather than searching cars for sale.
The short answer
- eBay Browse API (vehicles): Approved eBay partners who want eBay listings, including Motors, in their own app.
- Vehicle Databases: Checking the past listing and sale history and value of a specific VIN.
Side by side
| eBay Browse API (vehicles) | Vehicle Databases | |
|---|---|---|
| Searches | eBay listings by keyword and category, with compatibility checks for parts against cars, trucks and motorcycles. | Data for one vehicle by VIN (and year/make/model for market value); no search of current inventory by location or make. |
| Returns | A subset of item details per search match, with full details from getItem. | For the Used Car API: previous listings, asking prices, mileage, listing dates, seller details and photos where available, plus market values. |
| Before the first call | An eBay developer account and app keys; production use of Buy APIs requires applying through the eBay Partner Network, a business-model review and signed contracts with eBay. | A free sign-up, which gives an API key and starter credits. |
| Free | Not stated on its pages | 15 free credits and an API key on sign-up. |
| Acting on a result | Not stated on its pages | Sales history records include seller type and seller details (such as dealer name), but these are past listings, not live offers. |
| Coverage | eBay marketplaces; vehicle compatibility attributes documented for the US marketplace. | United States. |
| MCP server | No official server listed | No official server listed |
