I'm not sure it matters, but you're using a very old libssh2 version.

3 is LIBSSH2_FX_PERMISSION_DENIED which is the actual SFTP code that is sent
from the server in the response and -31 is the return code from libssh2 which
is named LIBSSH2_ERROR_SFTP_PROTOCOL.

So, the server rejects the command curl sends it.

I don't know, it will take a little debugging to see what is sent in this case
compared to the login and do mkdir that you mentioned (I trust you truly use
SFTP when you do that manual mkdir that compare with and not plain SSH).
