Hello, thank you so much for your recommendations!
For the domain name, I was waiting to see if the project would really take off. I'm going to purchase a shorter and better domain name today. 
As for creating a full script API similar to Linkvertise, I'll get started right away and aim to complete its development today. I’ll reach out to you once I’ve finished all these updates.

Hello! 
Just a quick update:
I’ve managed to create a script that works as you requested. To give you more details, the API will make a request every 500ms
to automatically shorten your links on the site.
For now, I’ve limited the API requests to 100 per hour, allowing you to run your tests
while I can monitor how much my server can handle. 
The script functions just like the example you mentioned. You only need to install the script obtained from this page: https://shortlink.gd-shops.com/dashboard/short-link
within the <head> tag of your site, and everything will happen automatically!

For domain names, I’m currently preparing a list of disposable domain names
that won’t have any issues with censorship or DMCA, as they are temporary.
