I've managed to get a proof of concept together that works with strawpoll.

The methodology to do so is as such:

Get / from http://strawpoll.me
Wait for all headers to be recieved
Digest headers, looking for the set cookie headers
Store the cookies

Once you have the cookies
Make a post to /api/v2/polls on strawpoll.me
Send Cookie header with request
Wait for all headers to be recieved
If you recieve HTTP/1.1 201 Created response
parse body to get link id

if not, you did something wrong


And the proof of concept: /strawpoll
Code:
alias strawpoll {
  sockopen strawpoll-start strawpoll.me 80
}
alias -l err {
  echo -a 04[StrawPoll]: $1-
}
alias -l out {
  echo -a 03[StrawPoll]: $1-
}

on *:SOCKOPEN:strawpoll-start:{
  if ($sockerr) {
    err SockOpen Error
  }
  else {
    out SockOpen
    var %s = sockwrite $sockname
    %s GET / HTTP/1.1 $+ $crlf
    %s Host: strawpoll.me $+ $crlf
    %s $crlf
  }
}

on *:SOCKWRITE:strawpoll-start:{
  if ($sockerr) {
    err SockWrite Error
  }
  else {
    out SockWrite
  }
}
on *:SOCKREAD:strawpoll-start:{
  if ($sockerr) {
    err SockRead Error
  }
  else {
    var %tmp
    sockread %tmp
    if ($regex(%tmp, /^Set-Cookie: ([^ ;]+)/i)) {
      strawpoll2 $regml(1)
      sockclose $sockname
    }
  }
}

on *:SOCKCLOSE:strawpoll-start:{
  if ($sockerr) {
    err SockClose Error
  }
  else {
    out SockClose
  }
}

alias strawpoll2 {
  sockopen strawpoll-post strawpoll.me 80
  sockmark strawpoll-post $1-
}

on *:SOCKOPEN:strawpoll-post:{
  if ($sockerr) {
    err POST -> SockOpen Error
  }
  else {
    out POST -> SockOpen

    var %p {"options": ["aa1", "bb2", "cc3", "dd4"], "title": "mytest from mIRC", "permissive": true, "multi": true}

}

alias -l sockwrite {
  echo -a 13[SockWrite]: $1 $replace($2-,$cr,\r,$lf,\n)
  !sockwrite -a $1-
}



If requested enough, I could write a script to manage options, title, etc and perform the post
