WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
Rip the asm macros for the basic FORTH words out of this and then embed them in a C binary, statically linked with your favourite libs for whatever task. Although I haven't tried this yet, I'm planning on doing it with ncurses for my own Roguelike. From there, if you can convert the function calls and your parameters down to raw numbers, you can send instructions to ncurses or whatever other API you like, directly from a FORTH stack.
