Please note: Customers with accounts in the Legacy Cirium Developer Center will need to create new accounts. The APIs have been completely rewritten and include new pricing and billing. You will need to review and accept the new terms and conditions. If you have specific contractual questions, please Contact a Cirium Representative.

Working With Cirium

When you sign up for a new account, you'll automatically be assigned the Evaluation plan, which offers a limited number of API transactions free of charge. The Evaluation plan is intended for initial development using the APIs.

Before transitioning to a paid account, please read and agree to the Terms and Conditions.

Once you're ready to buy, enter your credit card information in the Account section of the Developer Center, and choose a paid plan.

The Commercial plan is intended to meet the needs of most API users. It offers access to most of the Flex APIs with volume-based pricing (you pay for what you use).

Important Note: Converting from the Evaluation Plan to the Commercial Plan will immediately disable your free trial access to any Premium APIs which are only available via the Contract Plan. If you need access to any Premium APIs, please contact us early to allow sufficient time to review contract terms and pricing with our Sales team.

If the the above plan does not meet your needs, please contact your Cirium sales representative or complete our Contact a Cirium Representative form to discuss custom contract and monthly billing options.
