Real examples: Not just theoretical stuff, but actual code samples.
Error handling: We all make mistakes, so knowing how to fix them matters.
Up-to-date content: Crypto is evolving, and so should your docs.
FCS API checks all these boxes, providing crypto API documentation that is easy to follow, with examples and clear error handling.

A Developer's Perspective on FCS API
