@seniorquico sorry, the question what's for @rp_st Ok, if it's a really hand made sdk, I understand and yes, it's what I'm looking also for Actix-Web (framework in Rust) but for the MVP, I can continue with fastapi. If I remember, Entity framework and another in C# are working well so yes, maybe it's not very hard to do all abstractions but it looks like crazy to don't respect the RFC, finally with the information from @rp_st , I understand why they're not respecting it.
