@Irame can you please add a little more context here or bind it with the open issue?
I see sample test file:

type
  TMyWinApiFunc = function(): Integer; winapi;
  TMyWinApiProc = procedure(); winapi;
function MyWinApiFunc(): Integer; winapi;
procedure MyWinApiProc(); winapi;

and guessing that DelphiAST is failing when parsing winapi key word?

I don't know if this is required. Win API calls are normally stdcall.
