Questions, answered

Why choose Auto.dev?

Auto.dev is used by automotive businesses of all sizes, from startups to enterprise companies. Our mission is to make automotive data accessible to every developer regardless of their budget or project size.

How does pricing work?

Start on the Free plan with 1,000 API calls included and no credit card required. Requests stop when you reach the limit, so you are never billed for something you did not choose. Growth and Scale are subscription plans billed monthly plus usage-based data rates. You can upgrade, downgrade or cancel anytime.

Can I try Growth or Scale before paying full price?

Yes: start Growth or Scale with a 7-day trial for a one-time $1. A payment method is required and is charged the $1 at checkout; your plan's subscription fee begins automatically at the end of the trial unless you cancel first. Any usage during the trial is billed at your plan's data rates. You can cancel anytime, including during the trial, to avoid the subscription charge. See our Terms for full details.

Can I cancel anytime?

Yes! Auto.dev is a subscription-based service and you can cancel anytime.

How many API requests can Auto.dev handle?

With continuous optimization, the infrastructure behind the Auto.dev APIs is built for scale, with blazing fast response times. You can use the Free plan to test the API and get a feel for the data.

How often is API data updated?

Auto.dev is integrated with multiple channels delivering real-time data, which is why the database used by the Auto.dev API is updated regularly, with dozens of updates per month.

What happens if I use all 1,000 included API calls?

On the Free plan your requests stop until the monthly reset. There is no card on file and no overage charge. Upgrade to Growth or Scale to keep going: they add endpoints, higher rate limits, and usage-based data rates beyond the calls included in your plan.
