For a lot of use cases I find .http files very convenient. Here is a documentation from Microsoft: https://learn.microsoft.com/en-us/aspnet/core/test/http-files?view=aspnetcore-8.0

There is some standard around the .http extension so they work in many IDEs and they can be implemented into CI pipelines. The Microsoft documentation should be enough, though, to get you started.

Just a tiny bit of context: we are getting fusion reactors to work in fifty years since 1950.

Is “leaving it in my pocket at the end of the day” a euphemism for “I stole it”?
