Smartcar vs OpenVan: common questions

Which is more reliable, Smartcar or OpenVan?

Only OpenVan is on our probe schedule so far (—% uptime over 90 days). The other is catalogued but not yet live-checked, so we can't compare measured reliability head-to-head — check the uncovered API's own status page for now.

Do Smartcar and OpenVan need an API key?

OpenVan needs no key, while Smartcar requires a free API key. If you want to start calling without signup, reach for OpenVan first.

Can I call Smartcar and OpenVan from the browser?

Only OpenVan is browser-friendly — it returns CORS headers over HTTPS. Smartcar needs a server-side call or proxy, so factor that into which one fits a front-end project.

Are Smartcar and OpenVan free for commercial use?

Smartcar has unclear commercial terms, and OpenVan has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
