I don't think you will be able to make use of it as real CGI; but to
read from stdin, you can use either ⍞ or FILE_IO functions.  Both seem
to work fine for me when used in a separate script file rather than in
interactive session.

Some of your options are thus:
ContentsOfPOST←⍞            ⍝ get single line of parsed character input
ContentsOfPOST←FIO∆fgets 0  ⍝ get single line of raw bytes

(Note: descriptor of stdin is zero.)

Or something like:
ContentsOfPOST←{⍵, FIO∆fread 0}⍣{⍺⊢FIO∆feof 0}''

to read up everything from stdin in one go (it might add unnecessary 0
at the end if length of input data is a multiple of fread's block size).

As a side note, you probably want to add -s at the end of your #! line.
