  • 39,000+ vehicle configurations, every one verified real against automotive history
  • 20M labor times · 75M torque specs · 270K+ fluid specs · battery fitments · DTC library · NHTSA recalls
  • Consistent conventions: same auth, same vehicle addressing, same response envelope across endpoints

Common questions

Why should I trust an open database?

Because we publish our accuracy work instead of hiding it: the vehicle catalog is dual-AI-verified against automotive history, 1.2M+ bad rows have been purged with public changelogs, fluid specs carry measured accuracy, and expert review desks verify high-stakes values against OEM manuals. Every row tells you its own confidence.

What does the free tier include?

Full read access to every endpoint at 7 requests/day — enough to prototype the whole integration before paying.

Is there an SLA?

Business tier gets priority support; Enterprise gets a 99.9% SLA with service credits and a direct line.
