If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following:
wget --no-verbose --no-parent --recursive --level=1\ --no-directories --user=login --password=pass ftp://ftp.myftpsite.com/

--no-parent : Do not ever ascend to the parent directory when retrieving recursively. 

--level=depth : Specify recursion maximum depth level depth. The default maximum depth is five layers. 

--no-directories : Do not create a hierarchy of directories when retrieving recursively.
