What can you buy with Eclipse credits?

I'm curious, what exactly can one purchase using Eclipse credits? Are there specific products or services that are exclusively available for payment with these credits? Are there any limitations or restrictions on what can be bought with them? Additionally, how do these credits compare to other forms of digital currency or traditional payment methods in terms of their versatility and acceptance? I'm eager to learn more about the purchasing power and potential uses of Eclipse credits in today's digital landscape.
