Bash / sh
Prerequisites
Almost none I’d say, just a unixoid operating system. Most inline-samples use bash all the time. It makes use of the popular curl command which one could say is the http client for that programming language.
Using a library
Kudos to Fritz Rehde who recently implemented a small bash-only library with minimal footprint.
Check the excellent documentation to get up and running quickly and doing stuff like below.
