build a website a simple api

I have an html page that a host locally on my desktop using iis and run on [login to view URL] (I attached the file). It a very simple recaptcha box. I want some sort of server that acts like a stack to receive my tokens. So every time I solve a recaptcha, the token will be sent to my server/website and will be added on the stack (this was the first request). Second request is that I could request a token from the website by sending an http request to the server/site, the site will pop the last added token from the stack and send it back in the response. The way we will test this is that I will solve a recaptcha from my local html page and then check the site if it received the token (site has to support real time interface so I dont refresh it, it will just show the tokens one after the other). After the token adds to the site stack, I will send an http request from a simple python script to retrieve the last token that was added. The site will be ONLY ONE real time page that receive and give tokens. Files you will need to update: -obviously my local html that I run so that you make it send the token to the server as soon as it solves. Note: I dont have server yet to host anything and I dont care about the name of the site. its simply a middle man between my local page and a script that retrieves a token from the server. Please give me any suggestion to which server/site to use Maybe I didn't describe everything to your full understanding so please ask questions. My budget to this is $75.
