Hi @per.kristensen,
Welcome to the Auth0 Community!
Unfortunately, there are no plans to increase the number of API calls for either Production or Development Environments.
Most of the time, Rate-Limits can be circumvented by revising your current architecture and design. In this situation, I suggest reaching out to your Technical Account Manager (TAM) to discuss your options.
In the meantime, please see the following FAQ on How to tell if you are approaching the Rate-Limit.
Please let me know if you have any further questions.
Thank you.
