Studios have an awesome feature: offering pricing tiers based on price.

But Stripe is not available in India, meaning I can't monetize my studio. If I embed Pickaxes on my site and accept payments, how do I limit the usage of all the tools?

Is there any option to allow users to bring their own key for unlimited usage? This would let me embed Pickaxes on my site, charge a fee, and users could use it as much as they want by adding their own key.
