How to run REST APIs using a shell script?

Question

How to or what's the best way to run (not call with curl) a REST API service using purely shell commands or scripts?

I would typically run APIs with Python using FastAPI, however, I was wondering if it is possible to do it in a less-Pythonic and more-Linux way.

I'd suggest a "more Linux way" is to use python. Use the best tool for the job. — glenn jackman

Do you mean you want to setup a web server by using purely shell commands or scripts? — Gino Mempin

On SO, see Minimal web server using netcat. You could also see the related Q&A's over at Unix & Linux, such as this Simple command line HTTP server and this Simple server that triggers script and responds. I would say though that since you're comparing it with FastAPI, ... you might not get the same set of functionalities/features with purely shell commands/scripts. — Gino Mempin

thnx @GinoMempin that's exactly what I was looking for. I wanted to setup a web server (API) that, on being called, triggers another script and then sends an API response with the output of that other script. With Python I guess I would have to do it through calling a sub process, and so I wanted to it more with pure shell. — average.everyman

Sampo is most likely what you're looking for.

Written in bash, it is a shell script API server you can run directly in your terminal or via container on Kubernetes.

It exposes endpoints which could trigger different actions, running a script among others.
