Hello @momala454, thanks for writing in!

The Openapi spec actually does have a definition for Price.recurring, and we have full types for this in other libraries but the problem our generator for stripe-php only generate classes for top-level resources and doesn't generate classes yet for the nested data structures inside.

This is definitely on our radar and an improvement we plan to make to the library, but I am reclassifying as a feature request and editing the issue name! We'll keep you posted.
