Simple Web Server

You can spin-up and host your own local web-server which will be accessible by anyone and which could allow you to either peek into something that happens inside EA instance atm or control some options remotely.

Code for creating and booting up the server is quite large, but could be just copy-pasted around if needed.

Steps

There are multiple steps to make everything work

you have to reference needed assemblies containing the actual web-server. This is done by using assemblyName type of references
add namespaces containing classes that you will use to boot up the server
setup the server itself and, most importantly, routes which control what exactly your server will be returning when some page is accessed
pick some free port, 52080 for HTTP and 52443 for HTTPS could be a good choice, but you can change them to whatever you want

Example

You can import the ready-made example from here: https://eu.eyeauras.net/share/S20250302232655ULHlLljgYANa

Create an aura with a script
Copy-paste, run it, there should be a line printed to console Starting web-server - this tells us that everything went fine
Access the page via CURL or browser

Note that Chrome and Edge DO NOT allow you to access HTTP websites anymore by default. Setting up sefl-signed certificate and HTTPS is just an extra step and I'll leave it to you and ChatGPT (I've tested it and it nailed it on the first attempt).

How it could be used?

The most obvious examply is controlling what happens in EA remotely OR feeding some informationg gathered by EA, such us results of image searchers, text searcher, etc somewhere, maybe to another instance of EA polling that data... Or some other script.

Another example could be controlling your injection-based bot that way - considering this is a full-blown web-server, you can build any kind of transport on top of it.
